SCFM = Standard Cubic Feet per Minute. This is 1 cubic foot of free air at standard atmospheric temperature and pressure (the standard conditions are usually 20°C/68°F and 1 BAR/14.7 PSIA).
CFM = Cubic Feet per Minute. Sometimes this is incorrectly used interchangeably with SCFM meaning free air. Unless the temperature and pressure are specified with CFM, the actual volume of gas flow can’t be determined.
SLPM = Standard Litres per Minute. Litres per Minute is a way to express the volume of airflow in metric terms. 1 SCFM = 28.3 SLPM

Compared to blowers, EXAIR products:
Yes, cycling or pulsing will reduce overall air use for more cost-effective operation by using the compressed air for only the time that is required to perform a specific function. This is possible because the actuation of EXAIR products is virtually instantaneous.
For improved efficiency, EXAIR’s Electronic Flow Control (EFC) allows you to control the flow of air with any one of the 16 programmable modes.
Jane, please link “Electronic Flow Control (EFC)” to https://www.caasafety.com.au/products/efc-electronic-flow-control/
OSHA is not an approval agency. However, EXAIR products do meet OSHA noise and pressure requirements.
EXAIR products are engineered to maximise the efficiency of your compressed air resources and reduce compressed air consumption, thereby helping to reduce your production costs.
More importantly, EXAIR products provide additional worker safety. They are OSHA compliant for dead end pressure [29 CFR 1910.242(b)] and noise levels [29 CFR 1910.95(a)]
Yes, EXAIR products can be used with any compressed inert gas.
No, a blower can’t provide enough pressure to operate EXAIR products.
Extensive engineering has been done on all EXAIR products to reduce the noise levels. As you look through the EXAIR catalogue or view the various sections of our website, you’ll notice that sound levels have been given at a standard working distance of 914mm (3') for most products. The noise level can be higher in some blowoff applications as the part configuration might produce wind shear. No sound level is given in this case.
Yes, EXAIR is a manufacturer and they can alter their product to suit specific requirements, such as odd length Air Knives, pre-set Vortex Tubes, special ionisers, etc. They can also make a completely new design for a product. Please call us on 1300 787 688 or +61 8 8983 3999 to discuss your application.
In most cases, poor performance can be attributed to restrictive air lines, fittings, quick connects or insufficient air supply. The system pressure may be at 6.9 BAR (100 PSIG), but pressure at the product will be a lot lower if it’s being starved for air. The installation and maintenance guide that came with the product will give you the correct air line sizes.
A good way to test is by installing a pressure gauge at the inlet of the product and then check the static pressure (with the product off) against the dynamic pressure (with the product running). Any large pressure drop indicates improperly sized air lines, a restriction in the line or the compressor doesn’t have the capacity to supply the volume of compressed air needed.
If the dynamic air pressure is within the operating range of the product, then check the product for dirt and contamination. If the nozzle(s) plug up, the product will not operate properly.
If none of the above solves your problem, please call us on 1300 787 688 or +61 8 8983 3999.
There are many factors that need to be addressed in order to recommend an appropriate EXAIR cooling product; for example, initial temperature, final temperature desired, size of the part, etc. Please call us on 1300 787 688 or +61 8 8983 3999 to discuss your application.
They are rated for temperatures from 1.6°C to 149°C (35°F to 300°F). Maximum operating pressure is 20.7 BAR (300 PSIG).
To properly recommend an EXAIR product for blowoff, there are many parameters that need to be addressed, such as the part configuration, speed of travel, etc. Please call us on 1300 787 688 or +61 8 8983 3999 to discuss your application.
No, Air Amplifiers amplify volume, not pressure. They use a small amount of compressed air to produce high volume outlet flows with low outlet pressures (well below 1 PSIG).
It’s best to evaluate the compressed air system if low pressure is a problem. Undersized lines, restrictive fittings, clogged lines or a maxed-out air compressor may be the problem
No, for the Vortex Tube to operate properly, the cold outlet should not be subject to any restrictions that would produce back pressure in excess of 5 PSIG. The hot end exhaust can withstand pressure up to 30 PSIG, depending on the cold fraction.
An Air Amplifier or Air Knife would restrict the flow of a Vortex Tube to the point where the back pressure is excessive and severely limit the Vortex Tube’s cooling capacity.
It would be unrealistic to expect a temperature decrease in the total output flow of either an Air Amplifier or Air Knife with chilled compressed air if the goal were chilled airflow. Compressed Air is only a small fraction of the total airflow output from these devices. The net temperature of the airflow out of the Air Amplifier or Air Knife will be a mix of compressed and ambient air, with the ambient air being the greater part of the volume. Effectively, the airflow is going to be the same or very close to the ambient temperature surrounding an Air Amplifier or Air Knife.
Super Air Amplifier = 135°C (275°F)
Aluminium Adjustable Air Amplifier = 135°C (275°F)
Stainless Steel Adjustable Air Amplifier = 204°C (400°F)
High Temperature Air Amplifier = 374°C (700°F)
Super Air Amplifiers are only available in aluminium; Adjustable Air Amplifiers are available in aluminium and stainless steel. All sizes of Super Air Amplifiers have a 2-bolt flange (except the 8" [203mm] Super Air Amplifier) moulded into the body for mounting; Adjustable Air Amplifiers need to be mounted externally or with hard piping.
The main difference is in the operation of the devices: Super Air Amplifiers incorporate a patented shim to set the air gap, allowing them to consume 40% less air than Adjustable Air Amplifiers. This patented shim design also allows for higher air amplification ratios than the Adjustable Air Amplifier models.
To decrease the air consumption of Adjustable Air Amplifiers and have a set air gap, the Super Air Amplifier Shims can also be used on the Adjustable Air Amplifiers.
Super Air Amplifiers are available in aluminium.
Adjustable Air Amplifiers are available in aluminium, type 303 stainless steel and high temperature stainless steel (1-1/4" model only).
On the positive pressure side of an Air Amplifier, a maximum of 4.6m (15') of duct is recommended; and, on the intake side, a maximum of 1.52m (5') of duct.
The diverging airflow increases as the airflow moves away from the Air Amplifier. The expanding size of the airflow diameter entrains more and more airflow, resulting in a much larger air volume.
Loosen the lock ring and back out or tighten the inner sleeve until you reach your desired gap opening. For a more accurate setting, the gap can be set with shim stock. Once you’ve set the gap opening to the desired dimension, tighten the lock ring to hold it in place. Then, if used, remove the shim stock from the gap.
The stock flow setting of the Adjustable Air Amplifiers is factory set with the use of a flow meter.
Yes, EXAIR Stay Set Hoses can be used with smaller sizes of EXAIR Air Amplifiers. Please call us on 1300 787 688 or +61 8 8983 3999 to discuss your specific requirements.
The Soft Grip Safety Air Gun is physically smaller and has a ¼” compressed air connection. The Heavy Duty Safety Air Gun is larger and has a 3/8” compressed air connection. Both styles can be outfitted with ¼”, 3/8” and ½” nozzles.
Yes, EXAIR Air Guns that are outfitted with an EXAIR Air Nozzle meet OSHA dead end pressure standard 29 CFR 1910.242(b) and noise level exposure standard 29 CFR 1910.95(a). They will safely produce full pressure at the nozzle to maximise force and velocity of the air.
Yes, all Super Blast Safety Air Guns have a spring-loaded valve that instantly shuts off if the operator drops the gun.
Aluminium pipe extensions are available in 6" (152mm), 12" (305mm), 18" (457mm), 24" (610mm), 36" (914mm), 48" (1,219mm), 60" (1,524mm) and 72" (1,829mm).
Yes – for Super Blast Safety Air Guns, aluminium extension pipes are available in 36" (914mm) and 72" (1,829mm).
Yes, the nozzles can be changed on the Safety Air Guns but you may need an adaptor for correct fit. Please call us on 1300 787 688 or +61 8 8983 3999 to discuss your specific requirements.
Yes, on Soft Grip Safety Air Guns with ¼” or 1/8” Super Air Nozzles attached, Stay Set Hoses can be used.
Chip Shields are made of durable polycarbonate.
In many cases, yes. However, most typical air guns have an internal restriction limiting the output pressure of the gun to less than 2.07 BAR (30 PSIG) so that they comply with OSHA dead end pressure requirements. These air guns will not work properly with EXAIR Super Air Nozzles. Because EXAIR Super Air Nozzles meet OSHA dead end pressure requirements, they eliminate the need for a pressure restriction in the air gun itself. EXAIR Safety Air Guns are designed for best performance with EXAIR Super Air Nozzles.
The Chip Shield part you’ll need depends on whether your Safety Air Gun has an extension or not.
If your Safety Air Gun has an existing extension, the Chip Shield would be:
Part Number | Description | Extension Diameter |
901220 | Chip Shield for Precision Safety Air Gun | 4.83mm – 7.11mm |
901221 | Chip Shield for 1/8” Extension | 9.14mm – 10.9mm |
901222 | Chip Shield for ¼” Extension | 12.4mm – 14.7mm |
901223 | Chip Shield for ¾” Extension | 18mm – 19.8mm |
If your Safety Air Gun doesn’t have an existing extension, you’ll need to know the thread size of the nozzle.
Part Number | Description |
901231 | Chip Shield Retrofit Kit for Safety Air Gun with 1/8” Nozzle |
901232 | Chip Shield Retrofit Kit for Safety Air Gun with ¼” Nozzle |
901233 | Chip Shield Retrofit Kit for Safety Air Gun with 3/8” Nozzle |
901234 | Chip Shield Retrofit Kit for Safety Air Gun with ½” Nozzle |
No, EXAIR Air Knives are designed to use compressed air. Blowers are large, expensive and noisy, and require significant mounting space with their 76mm (3") to 152mm (6") outlet connections. And, they do not produce enough pressure to operate an EXAIR Air Knife.
We always recommend using the lowest pressure possible for the application. A pressure regulator should be used on the compressed air supply – start low and increase pressure to the point where the application problem is solved. The maximum pressure of the Air Knife (Super or Standard) is 17.2 BAR (250 PSIG).
Before increasing the gap of the Air Knife (installing thicker shims), it’s important to know that the Air Knife is working properly. Low flow could be caused by undersized lines, restrictive fittings, a clogged filter, an undersized compressor or dirt clogging the slot of the Air Knife. Using a pipe tee, install a pressure gauge at one of the inlets of the Air Knife to ensure that the full line pressure is available to it. If full line pressure is available and you require additional flow, shut off the compressed air and disassemble the Air Knife. If there is dirt present, clean all of the component parts and reassemble without installing the thicker shim (or additional shims). If all parts appear to be clean, we suggest you install the next higher thickness shim as this can produce a dramatic change in air volume and velocity. Ensure each screw is snugly tightened (7.5 ft/lbs). Increase the shim thickness by .001" (.03mm) increments until your desired performance is achieved.
Before it is shipped, the flow characteristics of the Air Knife are tested. First, follow the disassembly procedure and inspect the Air Knife for dirt contamination. Cleaning guidelines can be found on the installation and maintenance sheet shipped with the Air Knife or the Adobe PDF version may be downloaded from the Literature & News menu on this website. Secondly, the Air Knife may not be receiving enough volume of compressed air. Don’t use restrictive fittings, undersized lines or filters that may not allow enough airflow into the plenum chamber of the Air Knife. Air Knives that are 18" (457mm) or longer must be supplied at two compressed air inlets at opposite ends of the Air Knife. Thirdly, the screws may have been over-tightened during mounting or reassembly. Screws should be tightened snugly (7.5 ft/lbs).
I see your Super Air Knives come in off-the-shelf lengths up to 108” (2743mm). What is the longest Air Knife available? Are there other lengths available that aren’t shown in the catalogue or on your website?
The longest single piece Super Air Knife that we offer is 108" (2743mm). If you require a longer length for your application, multiple Super Air Knives can be connected end-to-end with the Super Air Knife Coupling Bracket Kit. This will produce a laminar, uninterrupted flow of air across the entire length. If you require a specific length Super Air Knife, EXAIR will make it for you.
For the Aluminium Air Knives, the polyester shims are:
0.001" (0.03mm) – Amber;
0.002" (0.05mm) – Red (installed in the Air Knife when it is shipped);
0.003" (0.08mm) – Green;
0.004" (0.10mm) – Tan.
For the Stainless Steel Air Knives, the stainless steel shims are only supplied in .002" (0.05mm) thickness.
For the PVDF Super Air Knives, the PTFE shims are only supplied in .002" (0.05mm) thickness.
EXAIR's Super Air Knives are available in aluminium, 303 stainless steel, 316 stainless steel, and PVDF (Polyvinylidene Fluoride). Super Air Knives are also available in PVC upon request.
Standard and Full Flow Air Knives are available in aluminium and 303 stainless steel.
Aluminium Air Knife with plastic shim: 82°C (180°F)
Stainless Steel Air Knife with stainless steel shim: 427°C (800°F). If the temperature exceeds 427°C, this may result in intergranular corrosion that can eventually plug the air gap opening.
PVDF Air Knife with PTFE shim: 135°C (275°F)
A higher force and airflow from your Air Knife may be achieved by increasing the volume of air being put through it. This is easily done by increasing the supply air pressure and/or using a shim set. Increasing the shim thickness within the knife will result in the air volume and force generated on a target increasing. Please remember that this will directly affect the volume of air that is required to properly supply the Air Knife; so, proper plumbing procedures should be applied when connecting the Air Knife to the compressed air source.
No, for the Vortex Tube to operate properly, the cold outlet should not be subject to any restrictions that would produce back pressure in excess of 5 PSIG. The hot end exhaust can withstand pressure up to 30 PSIG, depending on the cold fraction.
An Air Amplifier or Air Knife would restrict the flow of a Vortex Tube to the point where the back pressure is excessive and severely limit the Vortex Tube’s cooling capacity.
It would be unrealistic to expect a temperature decrease in the total output flow of either an Air Amplifier or Air Knife with chilled compressed air if the goal were chilled airflow. Compressed Air is only a small fraction of the total airflow output from these devices. The net temperature of the airflow out of the Air Amplifier or Air Knife will be a mix of compressed and ambient air, with the ambient air being the greater part of the volume. Effectively, the airflow is going to be the same or very close to the ambient temperature surrounding an Air Amplifier or Air Knife.
No, an Air Knife is not position sensitive, so the airflow is effective in any direction.
No, due to the internal machining of an Air Knife, field modification is not possible. Cutting the Air Knife would expose the internal plenum with no practical means of resealing it. If you require a specific length Air Knife, EXAIR will make it for you.
Yes, EXAIR Stay Set Hoses can be used with the shorter lengths of Air Knives. Please call us on 1300 787 688 or +61 8 8983 3999 to discuss your specific requirements.
There are three mounting options:
EXAIR’s Universal Air Knife Mounting System can be used for all styles of Air Knives and Ion Air Knives.
Use existing mounting holes/cap screws:
(a) The Super Air Knife has 1/4-20 tapped holes on 2" centres along the length of the Air Knife which can be used for mounting.
(b) With the Super or the Standard Air Knife you may choose to replace the existing cap screws with longer 1/4-20 threaded fasteners for mounting.
(c) Along the length of the Full-Flow Air Knife there are 10-24 tapped holes on 1-1/2" centres knife that can be used for mounting. Or, the existing 10-24 cap screws may be replaced with longer threaded fasteners.
You can hard plumb the compressed air lines to both ends and use the piping to support the Super and Standard Air Knives. Plumbing to both ends is required for Air Knives 24" (610mm) and longer but is also perfectly acceptable for shorter lengths.
The Plumbing Kit helps ease the installation of the longer Air Knives. Any Air Knife that is 24" (610mm) or longer should be plumbed with compressed air supplied into two or three inlets, depending on the length. The Plumbing Kit will connect the necessary air inlets of the Air Knife with the properly sized hose and fittings. It simplifies the installation of the Air Knife as only one individual connection will need to be hooked up to your compressed air supply. You can choose to install the plumbing kit yourself or have EXAIR install it at the factory.
EXAIR offers one-piece lengths from 3” to 108” (76mm to 2743mm) for the Super Ion Air Knife and 3" to 48" (76mm to 1219mm) lengths for the Standard Ion Air Knife. Custom lengths are also available. Please call us on 1300 787 688 or +61 8 8983 3999 to discuss your specific requirements.
EXAIR has a large selection of compressed air nozzles to suit a wide variety of applications. There are quick-pick charts in the EXAIR catalogue showing standard force and high force nozzles. There is also a selection guide on our website. These charts list each nozzle with relevant data to help you compare the nozzles against one another including: connection size, force, and sound level. You can easily select the nozzles that most closely match your important application factors. If you’d like assistance, please call us on 1300 787 688 or +61 8 8983 3999 to discuss your specific requirements.
Super Air Nozzles are engineered to significantly reduce sound levels and compressed air costs whilst still providing excellent blowing force for your application.
Noise levels and dead end pressures are serious safety concerns presented by open air lines. EXAIR's Air Nozzles will provide significantly lower air consumption and noise levels whilst maintaining OSHA-mandated dead end pressure levels. They may not provide the same blowoff force as an open air line operating at the same supply pressure due to the considerable reduction in air consumption. Many applications do not need the high force of an open air line. If you need higher force for your application, we can provide a larger nozzle to produce the necessary force while still maintaining OSHA safety.
EXAIR Air Nozzles differ in flow, force, material and force.
Yes, EXAIR Stay Set Hoses are designed for use with EXAIR Safety Air Nozzles and Air Jets.
Super Air Nozzles are available in zinc aluminium alloy, PEEK and type 316 stainless steel.

Models 1100-PEEK, 1102-PEEK, 1104-PEEK, 1108-PEEK, 1109-PEEK and 1110-PEEK are made of plastic.
Yes, EXAIR Air Nozzles are engineered for safety. They meet OSHA dead end pressure standard 29 CFR 1910.242(b) and noise level exposure standard 29 CFR 1910.95(a).
The design of EXAIR Stay Set Hoses minimises deflection. They are engineered to maintain their position during operation.
EXAIR Stay Set Hoses are rated for temperatures up to 55°C (158°F).
EXAIR Stay Set Hoses are rated to a maximum pressure of 17.2 BAR (250 PSIG).
Yes, EXAIR Stay Set Hoses can be used with smaller sizes of EXAIR Air Amplifiers and Air Knives. Please call us on 1300 787 688 or +61 8 8983 3999 to discuss your specific requirements.
EXAIR has an extensive range of air conveyors:
For short runs and small transfer rates, the Light Duty Line Vac performs best.
The Line Vac is designed for longer runs and greater transfer rates than the Light Duty Line Vacs.
Heavy Duty Line Vac is EXAIR's most powerful and robust conveyor. It is made of hardened alloy that resists abrasion and prevents premature wear. The Heavy Duty Line Vac conveys more material in less time over longer horizontal and vertical distances.
Please call us on 1300 787 688 or +61 8 8983 3999 to discuss your specific requirements.
There are many factors that affect the conveying rate and some of these are: Line Vac size, inlet pressure, conveying distance, vertical lift, bends in the conveying line and the type of material being conveyed. Any one of these variables can have a remarkable effect on performance, so we suggest that the Line Vac is tested in the application to verify results. EXAIR’s Application Engineers and can help determine if the Line Vac will work based on the application requirements and assist in selecting the proper size Line Vac for the application.
Please call us on 1300 787 688 or +61 8 8983 3999 to discuss your specific requirements.
No, the Line Vac is not designed to convey liquids. The Line Vac will vacuum up some liquid, but not in a solid column. The liquid and air will mix to create an output flow of atomised liquid that will spray out the end of the conveying tube.
Generally, the Line Vac should be placed within 1 metre, or closer if possible, of the suction point. It’s always easier to blow material through a pipe or hose than it is to vacuum it through. Bear in mind that this is a guideline only. If it’s not possible to get the Line Vac that close, then place it as close as possible to the suction point.
There is the potential that the Line Vac can produce a static charge caused by the material being transported.
Yes, you can convey powder with a Line Vac. However, the discharge end of the Line Vac can potentially be very dusty, so you need to separate the bulk powder from the air moving the powder. This can be accomplished by having a filter or centrifugal separator on the containment vessel at the discharge end of the Line Vac.
No, quality conveying hose is readily available from your local hose suppliers. Spiral reinforced hose is recommended together with worm gear hose clamps to connect the hose to the Line Vac.
On 2" (51mm) and larger diameter Air Wipe models, it is recommended that a gap of 13mm (1/2") is maintained between the outside of the target material and the inside diameter of the Air Wipe. Smaller diameter models can have a lesser airflow gap. This gap allows the secondary volume of air to be pulled in around the target material to enable higher blowing force to remove the contaminants.
The airflow impacts the product surface at a 30° angle (60° included angle).
With or without the high temperature hose attached, the maximum temperature limit for the Super Air Wipe is 427°C (800°F). Please call us on 1300 787 688 or +61 8 8983 3999 to discuss your specific requirements.
For safety reasons, the maximum pressure rating of the Super Air Wipe and Standard Air Wipe is 17.2 BAR (250 PSIG). We always recommend using the lowest pressure possible for the application, which helps to conserve compressed air. It is important to use a pressure regulator on the compressed air supply as this will allow you to increase the pressure to the point where the application problem is solved.
Yes, the Super Air Wipe is also available in stainless steel. For other materials, please call us on 1300 787 688 or +61 8 8983 3999 to discuss your specific requirements.
The air exits the Standard Air Wipe and Super Air Wipe at a 60° included angle. The airflow impacts the target material at a 30° wiping angle.
The Super Air Wipe and Standard Air Wipe may be mounted in a variety of ways, the most common being to use the compressed air pipe to support them. There are NPT female threads on each half (NPT/BSP adaptors are included) into which the compressed air supply pipe can be threaded. Position the Air Wipe where you want and then strap the pipe into place. Alternatively, mount the Air Wipe using the 1/4-20 tapped holes on the base of the Air Wipe. There is about 10mm (3/8") depth of thread to use for a bracket to be bolted to the bottom of the Air Wipe.
No, an Air Wipe would restrict the flow of a Vortex Tube creating excessive back pressure and severely limit the cooling capacity of the Vortex Tube. For proper operation, the Vortex Tube cold outlet should not be subjected to any restrictions that would produce back pressure in excess of 5 PSIG.
External Mix Atomizing Spray Nozzle - 800 Centipoise
Internal Mix Atomizing Spray Nozzle - 300 Centipoise
Siphon Fed Atomizing Spray Nozzle - 200 Centipoise
The maximum temperature rating is 204°C (400°F).
The Atomizing Spray Nozzles are pre-set by the factory in the fully open position. Turn the stem clockwise to reduce or stop flow being careful not to over tighten the stem, which can damage the stem or liquid cap. Once completely closed, 3 to 4 turns counterclockwise will result in a fully open flow.
Siphon Fed Atomizing Nozzles can draw up to 36" (914mm) height. If drawing from a container, you would want the bottom of the container to be no lower than 36" (914mm) below the liquid inlet to the Atomizing Nozzle.
The Atomizing Nozzles were tested with ordinary tap water to obtain the published performance data. The style of Atomizing Nozzle that’s best for your application will be determined by the viscosity of your fluid. Please call us on 1300 787 688 or +61 8 8983 3999 to discuss your specific requirements.
Both the liquid cap and the air cap are stamped with part identification. Please call us on 1300 787 688 or +61 8 8983 3999 with the combination of the two identification numbers to help us identify your Spray Nozzle.
NEMA 12 are stainless steel internally and aluminium externally.
NEMA 4 are aluminium.
NEMA 4X are type 303 stainless steel and are also available in type 316 stainless steel.
To determine the correct model for your application, we first need to determine the total heat load to which the control panel is subjected. This total heat load is the combination of two factors - heat dissipated inside the enclosure and heat transferred from outside into the enclosure. We're happy to help you calculate your heat load. You can call us on 1300 787 688 or +61 8 8983 3999; or fill out our easy online form and we'll do the calculations for you. Please click here for our Cabinet Cooler Sizing Guide.
No, as the cold air produced by the Cabinet Cooler is introduced into the enclosure, it expands to atmospheric pressure and warms to the temperature of the enclosure. There is the potential for condensation only if humidity from ambient air is allowed into the panel. For this reason, it is imperative that all louvres and other openings are closed off. On initial start-up, the Cabinet Cooler will purge out the warm, moist air from inside the panel. As the cool air generated from the Cabinet Cooler enters the panel, it starts to pick up heat and the relative humidity drops. A continuously operating Cabinet Cooler will stabilise the relative humidity inside the panel at approximately 45%. We also recommend using a 5-micron filter separator to remove any condensate from the airline.
Yes, a Cabinet Cooler will operate at less than 100 PSIG, but the cooling capacity will decrease depending on the inlet pressure. We recommend operating Cabinet Cooler Systems with 100 PSIG of compressed air pressure at the required volume.
Yes, Cabinet Coolers are simply Vortex Tubes engineered for the specific purpose of cooling a cabinet. A Vortex Tube will perform the same as a Cabinet Cooler, but there are distinct advantages to using the Cabinet Cooler for cooling a panel:
Cabinet Coolers are available in models that are UL Listed to maintain the NEMA (IP) integrity of electrical panels. Vortex Tubes do not provide this level of protection.
Cabinet Coolers have built in sound attenuation.
Cabinet Coolers have a built-in vent to allow warm air to escape from the cabinet.
Cabinet Coolers are pre-set for maximum refrigeration and the setting cannot be changed. Vortex Tubes can be adjusted in the field, leaving them susceptible to mis-adjustment and inefficient operation.
NEMA 12, NEMA 4 and NEMA 4X Cabinet Cooler Systems are rated up to 51.6°C (125°F).
High Temperature Cabinet Cooler Systems are rated up to 93.3°C (200°F).
NEMA 12 Cabinet Cooler Systems have built in sound attenuation and do not normally require additional muffling. If you’d like more attenuation, the optional muffler for the NEMA 12 Cabinet Cooler Systems is part number 4902.
Yes, to be able to change the temperature setting, you will need liquid at the desired set temperature, a continuity meter, and a small flat head screwdriver. The product’s installation and maintenance guide describes the process for adjusting the thermostat.
"Temp Guns" read surface temperature of the material they are aimed at, instead of air temperature. To accurately calculate the internal heat load of the cabinet, we need to know the current external and internal air temperatures of the cabinet. EXAIR recommends using a simple air temperature thermometer.
Yes, UL Listed NEMA 12 models may be mounted in any orientation (horizontal, diagonal, etc…). Using our 90° side mount kit, you can save some space by positioning the Cabinet Cooler vertically. It is very important that NEMA 4 and NEMA 4X models are mounted in the vertical orientation to maintain their UL Listed NEMA integrity. Our 90° side mount kits make side mount installation simple, clean and effective.
The ETC may be adjusted from 27°C to 49°C (80°F to 120°F).
The maximum environmental temperature for the ETC is 65°C (150°F).
EXAIR Cabinet Cooler Systems are available with cooling capacities from 275 Btu/hr to 5,600 Btu/hr. For even higher heat load requirements, multiple systems or additional Cabinet Cooler units are occasionally specified. For more information, please contact us.
The air is distributed through the cabinet by the Cabinet Cooler System via the Cold Air Distribution Kit, which is needed because the Cabinet Cooler itself is self-exhausting. This means that all the air that is put into the cabinet by the Cabinet Cooler unit is exhausted through the body of the unit. So, to ensure you’re allowing the cold air to properly cool the cabinet and that only the warm air is exhausted, you’ll want to use the Cold Air Distribution Kit to carry the cold air away from the exhaust port.
If you purchased your Cabinet Cooler System after 2nd January 2008, there will be a small round silver label on the body of the Cabinet Cooler near the compressed air inlet that shows the air consumption in SCFM at 100 PSIG.
The "Temp Gun" will read the surface temperature of the material at which they are aimed, instead of air temperature. So that we may accurately calculate the internal heat load of the cabinet, we need to know the current external and internal air temperatures of the cabinet. A simple air temperature thermometer is recommended.
The chattering is caused by a slow change in temperature inside the enclosure. Included with the Model 9017 Thermostat is a Model 4519 Capacitor. This .002 microfarad capacitor should be wired across the leads of the thermoswitch to desensitise it and eliminate the chattering.
The ETC has the following benefits:
Maybe. Designed specifically to control EXAIR Cabinet Coolers, the temperature range of the ETC is limited to a range that is appropriate for the application. Provided that the temperature required for your application fell within the 27°C to 49°C (80°F to 120°F) range of the ETC, then it could be used in conjunction with an EXAIR Vortex Tube. Please call us on 1300 787 688 or +61 8 8983 3999 to discuss your specific requirements.
The maximum environmental temperature for the ETC is 65°C (150°F).
No, all EXAIR E-Vac's have a straight through design that allows dust and contaminants to flow through without causing damage.
The Reversible Drum Vac creates a vacuum in any closed-top 205-litre (44-gallon) drum and is designed to pick up liquids. It can also empty the drum by inducing a pressure into the drum. A sensitive pressure relief valve designed into the Reversible Drum Vac eliminates the risk of over-pressurisation of the drum.
The Reversible Drum Vac has no moving parts so any degradation in performance is probably due to contamination from the compressed air supply. If provided with proper air filtration, maintenance on the Reversible Drum Vac is not normally required. The Installation and Maintenance Guide that came with your unit describes how to disassemble and clean the unit. Also, if the element of your filter separator is clogged with dirt, large pressure drops are possible. Check the filter and replace the element if necessary. A troubleshooting guide is available for the Reversible Drum Vac.
Yes. Standard vacuum hoses are available in 3.05m (10') and 6.1m (20') lengths. Custom lengths of PVC hose are available by special order. Note: The Reversible Drum Vac is designed for use with a 3.05m (10') hose; the High Lift Reversible Drum Vac is designed for use with a 6.1m (20’) hose. Depending on the application, longer hose lengths may affect performance.
Yes, the Reversible Drum Vac may be suitable for use with chemicals other than coolant. Contact us for a list of the materials of construction for the various Reversible Drum Vac components, which will allow you to ascertain if the specific fluid or chemical you are using will be appropriate for use with the Reversible Drum Vac components.
The Reversible Drum Vac has the potential to produce a static charge caused by the material being transported.
At 5.5 BAR (80 PSIG) inlet pressure, the Reversible Drum Vac can produce approximately 2.74m (9') of vertical lift. At the same inlet pressure, the High Lift Reversible Drum Vac can produce approximately 4.57m (15') of vertical lift.
Yes, the Reversible Drum Vac will simply take more time to pressurise a larger vessel and pump the liquid out. Caution: Ensure your vessel is rated to more than 5 PSIG burst strength as the Reversible Drum Vac will produce up to 5 PSIG internal pressure.
Yes, a 5-gallon capacity Reversible Drum Vac System that includes the drum is available.
Effective on a wide range of fluids, from water and water-based coolants to motor oil, the pumping rate of the Reversible drum Vac is affected by the viscosity of the fluid. Water can be pumped at a rate of approximately 114 litres (37 gallons) per minute at 5.5 BAR (80 PSIG) inlet pressure. Hydraulic oil can be pumped at a rate of approximately 38 litres (10 gallons) per minute, and 15W40 motor oil can be pumped at a rate of approximately 26.5 litres (7 gallons) per minute.
As it has a PVC standpipe, the maximum temperature rating for the Reversible Drum Vac System is 60°C (140°F).
No, the Reversible Drum Vac is designed to vacuum liquids. For vacuuming dry materials, use either the Chip Vac, Heavy Duty Dry Vac, Heavy Duty HEPA Vac or EasySwitch Wet-Dry Vac.
No, the Reversible Drum Vacs are designed for and specified for use on steel drums only.
5 Gallon Drum:
Volume - 18.9 litres
Diameter - 381mm (15")
Height - 267mm (10.5")
There are two groups of EXAIR products that should not be used around flammable materials – the conveying products and the static eliminators. The Line Vac, Reversible Drum Vac, Chip Vac, Heavy Duty Dry Vac, Heavy Duty HEPA Vac, Vac-u-Gun and Chip Trapper conveying products all have the potential to produce a static charge caused by the material being transported. High voltage technology is used by all the static eliminating products to eliminate a static charge. There is the possibility that the high voltage emitter points could produce a spark.
The Chip Vac is used to vacuum up dry or wet chips from fixtures, floors and work surfaces of machining centers, lathes, saws, mills and other industrial equipment.
For Australian customers, the Chip Vac is available to suit 205-litre (44-gallon) drums as well as the 5-gallon Mini Chip Vac System. The 5-gallon size is the only model which automatically includes the drum.
Yes, the Chip Vac can be purchased with a longer hose. Standard vacuum hoses are available in 3.05m (10') and 6.1m (20') lengths. Custom lengths of PVC hose are available by special order. Note: The Chip Vac is designed to be used with a 3.05m (10') hose. Depending on the application, longer hose lengths may affect performance.
The Chip Vac performs best with one vacuum hose. There are other EXAIR products that may be better suited to your application.
There is the potential that the Chip Vac can produce a static charge caused by the material being transported.
The Chip Trapper's Filter Bag is made of polyester and is washable and re-usable. The bag is available in 1, 5, 25, 50, 100, and 200-micron ratings.
There are two 5-micron filter bags included with the Chip Trapper unit. The available filtration sizes are 1, 5, 25, 50, and 200-microns. The bags may be purchased separately or one of each size is included in the sample pack.
The Chip Trapper filter bags has a capacity of 0.0202 mᵌ (.713ftᵌ or 5.33 US gallons). The weight capacity is 6.8kg (15lbs)
It’s helpful to know how much air you’re currently using. You can either make an estimate or use our Digital Flowmeter to determine your system’s air consumption. The Digital Flowmeter is available from 1/2" - 8" (13mm – 203mm) pipe sizes. Once you know your current air consumption you can use this calculator to determine savings.
Yes, CAA and EXAIR are committed to more efficient use of compressed air and recommend limiting its use to only the duration required to perform a specific function. EXAIR products’ effects are virtually instantaneous so cycling increases efficiency and will reduce overall air use for more cost-effective operation. An EXAIR Electronic Flow Control (EFC) will enable you to control the flow of air with any one of the 16 programmable modes.
No, the EFC can’t handle the current draw of 2 solenoid valves.
The EFC will accept input voltage from 100-240VAC. The internal power supply converts input voltage to 24VDC output voltage to operate the sensor, solenoid valve and timer.
Providing an automatic control to turn the air flow on and off as required, the EFC is a very simple way to increase the compressed air efficiency of EXAIR's products. You won’t need to rely upon any manual valve, which can easily be forgotten, and its fast-acting valve will even save you air in between parts. To determine the return on investment for the EFC, use this calculator.
Select the EFC should according to the rated volume of flow (SCFM or SLPM). Simply choose the EFC that has sufficient flow capacity (SCFM or SLPM) to operate your compressed air product.
EXAIR has extensively engineered all their products to reduce the noise levels. Paging through the catalogue or looking at the various sections on our website, you’ll notice that the sound levels have been given at a standard working distance of 914mm (3') for most EXAIR products. The noise level of some blowoff applications can be higher due to the part configuration that might produce wind shear. In this case, no sound level is given.
An important tool in any compressed air optimisation program, EXAIR's Ultrasonic Leak Detector can find compressed air leaks in your system, which can then be repaired. By repairing leaks, you can increase your compressor output by up to 30%.
No, connecting both the Summing Remote Display and the Data Logger will have no effect on the accuracy of the Digital Flowmeter.
To better understand your requirements, the Digital Flowmeter should be installed at each major leg of your compressed air system. It is meant to be a permanent installation to provide feedback of compressed air consumption. We don’t recommend uninstalling the Digital Flowmeter but it can be done with the use of a pipe repair clamp.
No, the Summing Remote Display has no connections. The USB Data Logger should be connected directly to the Digital Flowmeter.
Installing the Digital Flowmeter at each major leg of your compressed air system will allow you to determine how much air you are using in applications and/or losing through leaks. This will allow you to install more efficient blowoff and end use compressed air components as well as quantify your savings. And, you can then be confident that your compressor has enough capacity for your various applications.
The standard cable length from EXAIR is 15.2m (50 linear ft.) and is the maximum recommended length for the cable.
Yes, we offer 3/4" to 4" (19mm to 102mm) Digital Flowmeters for type L copper pipe; and 25mm to 102mm aluminium pipe. Please specify the type of pipe you are using.
(1) Rate Mode: Duplicates the reading of the Digital Flowmeter to which it is connected.
(2) Daily Usage Mode: Displays the usage in thousands of standard cubic feet during the most recent 24-hour period.
(3) Cumulative Usage Mode: Displays the total air usage in thousands of standard cubic feet since the unit was energised. NB: If necessary, the decimal point can be moved to change the resolution. The meter will roll back to 0 after reaching 9,999.
On the side of the housing there is a small button used to toggle between the display modes.
You could mount the Digital Flowmeter to a section of pipe with couplings that would allow it to be relocated to any area you wish to test. You’ll need to keep in mind these restrictions:
Yes, the Digital Flowmeter provides Milliamp (4-20mA), Pulse, and Serial Communication (RS-485) outputs.
Below is a list showing the calibrated ranges for each Digital Flowmeter. The documented accuracy within these ranges is 5% of the reading, plus 1% of full scale for air temperatures between 4°C - 49°C (40°F - 120°F):
Part Number | Description | Flow Range |
9090 | 1/2 Schedule 40 Steel Pipe | 1-90 SCFM |

9099 | 5" Schedule 40 Steel Pipe | 20-2,500 SCFM |
X121608 | 6" Schedule 40 Steel Pipe | 30-3,000 SCFM |
The units will read flows up to 50% more than the maximum calibrated range; accuracy is 7% of the reading for air temperatures between 4°C - 49°C (40°F - 120°F).
Included with the Summing Remote Display is a 15.2m (50') long cable to attach to the Digital Flowmeter. For proper operation, the maximum length of cable that can be used is 18.3m (60').
We offer NIST traceable calibration and repair for damaged units for the Digital Sound Level Meters. Please call us on 1300 787 688 or +61 8 8983 3999 for details.
Static Eliminators combined with EXAIR engineered airflow products are ideal for hard-to-reach places or obstructed surfaces, products moving at high speeds, and surfaces with an extremely high charge. Air assisted ionisers include the Super Ion Air Knife, Standard Ion Air Knife, Super Ion Air Wipe, Ion Air Cannon, Ion Air Gun and the Ion Air Jet.
For situations where even the smallest amount of airflow can disturb the product, or space is extremely limited, Static Eliminators without air are available. These types of static eliminator must be mounted within 2 inches (51mm) from the charged surface. Ionisers without air include the Ionizing Bar and Ionizing Point.
Please call us on 1300 787 688 or +61 8 8983 3999 to discuss your specific requirements.
Due to the air turbulence created by the ducting and the recombination of the ions, EXAIR does not recommend ducting its ionisation products. Ducted EXAIR ionisers have been successful in applications where diminished performance was acceptable.
Use a soft bristle brush (a toothbrush works well) to clean the emitter points and channel to remove any particulate. Do not use anything that will bend or dull the emitter points; and, do not use any soaps or liquid cleaners that will leave conductive residue, which can destroy the effectiveness and lifespan. To eliminate potential performance problems, add a simple cleaning operation to your planned maintenance schedule. The cleaning frequency required will depend upon the environment in which the ioniser is installed. A dirty industrial application may require daily cleaning while a clean-room application may require only monthly cleaning. It’s important to evaluate the cleaning needs of each individual ioniser installation.
Never clean an ioniser with the power on!
Static Eliminators are not designed to demagnetise objects. Magnetic attraction and static attraction are two completely different phenomena that have nothing to do with each other. EXAIR Static Eliminators reduce static charges by providing positive and negative ions to the surface of a material to bring the total static charge back to neutral. Magnetic attraction is caused by lines of force created by the alignment of atoms in magnetised material.
There are two groups of EXAIR products that are not for use around flammable materials – the static eliminators and the conveying products.
The Line Vac, Drum Vac, Chip Vac and Heavy Duty Dry Vac conveying products all have the potential to produce a static spark caused by the material being transported.
The static eliminating products utilise high voltage technology to eliminate a static charge and the high voltage emitter points could possibly produce a spark.
To completely eliminate the charge, the ioniser floods the product's surface with positive and negative ions. A new charge may be generated if that part or material experiences friction where it rubs against another surface.
The model 7905 Static Meter will help you to pinpoint the location of the static trouble spots in your application. It will indicate surface voltage and polarity up to ±20 kV at a spacing of one inch (25mm) with an accuracy of 10% full scale.
EXAIR Super Ion Air Knives are available in one-piece lengths from 3” to 108” (76mm to 2743mm), and Standard Ion Air Knives in 3" to 48" (76mm to 1219mm) lengths. Custom lengths are also available. Please call us on 1300 787 688 or +61 8 8983 3999 to discuss your specific requirements.
Yes, an EXAIR Super Air Knife or Standard Air Knife can be retrofitted to your existing Ionizing Bar quite easily. Simply let us know the length of your Ionizing Bar and we can specify the parts you will need to be able to convert the Ionizing Bar to a Super ion Air Knife or a Standard ion Air Knife. Please call us on 1300 787 688 or +61 8 8983 3999 to discuss your specific requirements.
Generally, the most effective place to install an ioniser is going to be just before the area of the process where the static field is creating problems (tearing, jamming, discharge to personnel, etc.) In some cases, multiple ionisers on a single process may be necessary due to static regeneration in the process. For cleaning applications, the ionser should be positioned just before the packaging or finishing operations. A model 7905 Static Meter is also available to help you pinpoint the areas in a process where the static is being generated. The Static Meter will measure the polarity and magnitude of a given static field.
Gen4 Selectable Power Supply models 7960 & 7961: In 115 VAC mode consume 0.2 Amps; and, in 230 VAC mode consume 0.1 Amps.
In 1928, a French physics student, George Ranque, was experimenting with a vortex-type pump he had developed when he noticed warm air exhausting from one end and cold air from the other. He soon forgot about the pump he had developed and started a small firm to exploit the commercial potential for this strange device that produced hot and cold air with no moving parts. However, the business soon failed, and the Vortex tube slipped into obscurity until 1945 when a German physicist, Rudolph Hilsch, published a widely read scientific paper on the device.
Previously, the great nineteenth century physicist, James Clerk Maxwell, hypothesised that since heat involves the movement of molecules, we might someday be able to get hot and cold air from the same device with the help of a "friendly little demon" that would sort out and separate the hot and cold molecules of air.
Consequently, the Vortex Tube has been variously known as the "Ranque Vortex Tube", the "Hilsch Tube", the "Ranque-Hilsch Tube", and "Maxwell's Demon". By any name, in recent years it has gained acceptance as a simple, reliable and low-cost solution to a wide variety of industrial spot cooling problems.
Vortex Tubes are a product of EXAIR Corporation. They use compressed air as a power source to produce cold air from one end and hot air from the other – with no moving parts. Generally, the cold air is used for refrigeration or spot cooling applications. The hot air can be used for spot heating applications, but the temperatures and volumes are not very high, so there is usually a better way to get hot air.
No, for the Vortex Tube to operate properly, the cold outlet should not be subjected to any restrictions that would produce back pressure in excess of 0.3 BAR (5 PSIG). Depending on the cold fraction, the hot end exhaust can withstand pressure up to 2.07 BAR (30 PSIG). The performance of the Vortex Tube will deteriorate if backpressure exceeds 0.3 BAR (5 PSIG).
An Air Knife or Air Amplifier would restrict the flow of a Vortex Tube to the point where the back pressure is excessive causing the cooling capacity of the Vortex Tube to be severely limited.
It would be unrealistic to expect a temperature decrease in the total output flow of either an Air Amplifier or Air Knife with chilled compressed air. Compressed air makes up only a small fraction of the total airflow output from these devices. The net temperature out will be a mix of compressed and ambient air, with the ambient air comprising most of the volume. Therefore, the airflow is going to be the same or very close to the ambient temperature surrounding an Air Knife or Air Amplifier.
Vortex Tubes are rated in Btu/hr. based on 6.9 BAR (100 PSIG) inlet pressure at 20°C (68°F). Any deviation of pressure or temperature will affect the rating of the Vortex Tube. To calculate the effects of temperature and/or pressure deviations on the Vortex Tube's rating, contact us for application support.
As it is a phenomenon of physics, no one knows exactly why a Vortex Tube works. Here is a description of how the air moves:
Compressed air, normally 5.5 to 6.9 BAR (80 to 100 PSIG), is injected tangentially through a generator into the vortex spin chamber. At up to 1,000,000 RPM, this air stream revolves toward the hot end where some escapes through the control valve. The remaining air, still spinning, is forced back through the centre of this outer vortex. The inner stream gives off kinetic energy in the form of heat to the outer stream and exits the Vortex Tube as cold air. The outer stream exits the opposite end as hot air.
For further details, please call us on 1300 787 688 or +61 8 8983 3999.
From supply air temperature, a Vortex Tube will provide a temperature drop on the cold end and a temperature rise on the hot end. Elevated inlet temperatures will result in a corresponding rise in both the cold and the hot end temperatures.
Yes, Cabinet Coolers are simply Vortex Tubes that have been engineered for the specific purpose of cooling a cabinet. Although a Vortex Tube will perform the same as a Cabinet Cooler, there are distinct advantages to using the Cabinet Cooler to cool an enclosure:
Approximate temperature drops (and rises) from inlet air temperature produced by a Vortex Tube set at each cold fraction are shown in the Vortex Tube performance charts. Assuming there is no fluctuation of inlet pressure or temperature, a Vortex Tube will reliably maintain temperature within ±-0.5°C (±1°F)
There are a few reasons why this may be happening.
If you have any further questions, or if these tips failed to solve your problem, please call us on 1300 787 688 or +61 8 8983 3999.
The Vortex Tube’s performance will deteriorate with backpressure on the cold end exhaust. Low backpressure up to 0.138 BAR (2 PSIG) will not change the performance; 0.345 BAR (5 PSIG) will change the performance by about 2.8°C (5°F).
No, for the Vortex Tube to operate properly, the cold outlet should not be subjected to any restrictions that would produce back pressure in excess of 0.3 BAR (5 PSIG). A Super Air Wipe would restrict the flow of a Vortex Tube to the point where the back pressure is excessive causing the cooling capacity of the Vortex Tube to be severely limited.
The Vortex Tube is the essential component inside all the applied cold airflow generating EXAIR products. Vortex Tubes are available in 3 different sizes and produce a wide range of cooling capacities. All models shown in the EXAIR catalogue and on our website have an adjustable valve at the hot end that can change the proportions of hot and cold airflow to their respective ends. If required, on special order, this valve can be replaced with a preset orifice that will provide a predetermined temperature drop or rise. A series of inserts, called "generators", are available that offer a wide range of flow rates for each Vortex Tube size. These generators allow you to size the flow to the application.
Most of the applied products (Cabinet Cooler, Cold Gun and Mini Cooler) have a preset total flow capacity that is ideal for that product. The hot end valve has been replaced with a preset orifice that allows the Vortex Tube to deliver the highest cooling capacity available. The Adjustable Spot Cooler is the exception – the temperature is adjustable and flow rates can be altered by using the interchangeable generators. These applied cold air products include other features that make them easy to mount and keep the sound levels low.
The best way to find out is to remove the hex cold cap and O-ring that hold the generator into the unit. Read the alphanumeric code on the flat surface of the generator, which will identify many of the features of the Vortex Tube. If you have a stock Vortex Tube, this will be all you need. If you have a Vortex Tube with special features, we can help you to determine what you have.
When you've obtained the alphanumeric code, please call us on 1300 787 688 or +61 8 8983 3999.
Vortex Tubes are available in 3 sizes with a variety of cooling capacities. Many of the common applications incorporating Vortex Tubes are shown in the EXAIR Catalogue and on our website. If your specific application is not shown but is similar to one of those described, it is best to order one of the EXAIR Cooling Kits. The Cooling Kits include a Vortex Tube, cold air muffler, air line filter and all the generators to allow you to experiment with various flows and temperatures. It is best to discuss your requirements with us so we can help you select the size for your application. Please call us on 1300 787 688 or +61 8 8983 3999.
There are several ways to determine the cold fraction setting of your Vortex Tube. One would be to use the performance data chart in the EXAIR Catalogue and on our website that displays the temperature drop and rise of the Vortex Tube at various temperatures and supply pressures. Measure the temperature of the cold air exiting the Vortex Tube and compare it to the chart. Ensure that the air temperature is measured immediately out of the Vortex Tube as the air stream will warm as it mixes with ambient air.
Another method is to use an air flow meter to measure the volume of air both going into and out of the unit and comparing the hot and cold flow rates of the unit. Comparing the hot or cold flow rate to the total will give you the relative cold or hot fraction setting.
For their Vortex Tube and Line Vac products, EXAIR recommends a 25-micron (or finer) filter separator; and a 10-micron (or finer) filter separator for their other products. These remove dirt, rust and water condensate that may be present in the compressed air. If there is oil in the compressed air supply, the use of a coalescing oil removal filter is recommended.
EXAIR product kits contain appropriately sized filters and regulators.
Yes, provided the flow requirement does not exceed the capacity of the filter separator. If you are unsure about the capacity of your filter separator, please call us on 1300 787 688 or +61 8 8983 3999.
