Air Nozzles and Jets Overview

Engineered Air Nozzles and Jets reduce noise levels and air costs.

Save energy and improve safety by upgrading your blowoff, cooling, and drying operation to the award winning Super Air Nozzles!

What Are Air Nozzles and Jets?

A simple solution to excessive air consumption and noise levels on compressed air blowoff operations. EXAIR Air Nozzles and Jets produce outlet flows up to 25 times compressed air consumption using a small amount of compressed air as the power source.

Air savings, compared to open copper tubes or pipes commonly used for blowoff can be as high as 80%. Less compressed air means less noise. The typical noise level reduction is 10 dBA. All EXAIR Air Nozzles and Jets meet WorkSafe Australia and OSHA maximum dead-ended pressure and sound level exposure requirements and carry the CE mark.

An open 1/4″ (6mm) copper tube, by contrast, ejects pure compressed air at up to 40 standard cubic feet per minute (1,133 SLPM), the entire output of a 10 horsepower compressor. Annual energy cost can exceed $1,000 per year. Noise levels in excess of 100 dBA are commonly produced. When supply pressure exceeds 30 PSIG (2 BAR), an open pipe, tube or drilled holes violates OSHA static pressure requirements.

How Air Nozzles Work

Air Nozzles use the Coanda effect to amplify compressed airflow up to 25 times or more. As illustrated above, compressed air (black arrows) is ejected through a series of nozzles on the outer perimeter. As the air travels along the outer wall of the nozzle, surrounding air (blue arrows) is entrained into the stream. The airstream that results is a high volume, high velocity blast of air at minimal air consumption. The air is always ejected so it can vent safely, well below OSHA dead end pressure requirements, should the nozzle end be blocked.

How Air Jets Work

airjet
Air Jets utilise the Coanda effect (wall attachment of a high velocity fluid) to produce air motion in their surroundings. As illustrated above, a small amount of compressed air (black arrows) is throttled through an internal ring nozzle above sonic velocity. A vacuum is produced, pulling large volumes of surrounding, or “free” air, through the jet (blue arrows). Both the outlet and inlet can be ducted for remote positioning. If the end is blocked, flow simply reverses at well below OSHA dead end pressure requirements.

Safe and Efficient Use Of Compressed Air

The inefficient use of compressed air for blowoff applications may create problems due to the energy costs, noise level and potential danger to personnel who are exposed to high pressure air. Open air pipes, copper tubes and drilled pipes are a few of the common abusers. They consume tremendous amounts of energy and often produce noise levels over 100 dBA.

Open Air Pipe or Copper Tube

Turbulent compressed air blasts straight out of the pipe or tube. It not only wastes huge amounts of compressed air but also violates OSHA noise and dead end pressure requirements.

Reduce Energy Costs

The best way to cut energy costs is through proper maintenance and use of the compressed air system. Leaks and dirty filters require maintenance on a regular basis. Energy savings can also be realised when replacing outdated compressor motors and controls with high efficiency models that often pay for themselves in a short period of time.

The most important factor to dramatically boost efficiency is proper use. Using engineered products like EXAIR’s Super Air Nozzles can cut operating costs since they use only a fraction of the compressed air of typical blowoffs. In addition, all of the Air Nozzles and Jets shown on this website can be cycled on and off with an instantaneous response. EXAIR’s EFC Electronic Flow Control is a control that limits compressed air use by turning on the air only when a part is present.

Saving Money and Compressed Air

The table above shows the air consumption for typical homemade blowoffs. For air consumption and other data on EXAIR’s Air Nozzles and Jets, please see Specifications

Consider the following example where a Model 1102 Mini Super Air Nozzles replaces an 1/8” (3.2mm) open pipe. The compressed air savings is easy to calculate and proves to be dramatic. Payout for Air Nozzles and Jets, including filter and installation cost is measured in weeks – not years, as is the case for other cost reduction equipment. Based on a 40-hour work week, 52 weeks a year.

Example:

  1. Existing blowoff is 1/8” (3.2mm) open pipe at 80 PSIG (5.5 BAR) supply.
    Air consumption, from the table above, is 70 SCFM (1,981 SLPM).
  2. Use a 1/8 Model 1102 Mini Super Air Nozzle also at 80 PSIG (5.5 BAR) supply.
    Air consumption, from the table under Specifications , is 10 SCFM (283 SLPM).
  3. Compressed air saved = 70 – 10 = 60 SCFM (1,981 – 283 = 1,698 SLPM).
  4. For this example, the blowoff is continuous. If the duty cycle was 20%, then air saved would be 60 x .2 = 12 SCFM (1,698 x .2 = 350 SLPM).
  5. Most large plants know their cost per 1,000 standard cubic feet of compressed air (10,000 standard litres). If you don’t know your actual cost per 1,000 SCF, $0.25 is a reasonable average to use. (Cost per 10,000 standard litres is approximately $0.089.)
  6. Dollars saved per hour = SCFM saved x 60 minutes x cost/1,000 SCF (SLPM saved x 60 minutes x $0.089/10,000)
    = 60 x 60 x $0.25/1,000 (= 1,698 x 60 x $0.089/10,000)
    = $0.90 per hour
    = $36.00 per week
    = $1,872.00 per year savings for One nozzle!

Reduce Noise Levels

High noise levels are a common problem for many plants. Compressed air noise often exceeds WorkSafe and OSHA noise level exposure requirements, resulting in hearing loss to those working in close proximity. Noisy blowoffs at 80 PSIG (5.5 BAR) that produce noise levels of 100 dBA can be reduced to only 74 dBA when using a Super Air Nozzle. At that pressure, it is still possible to obtain hard-hitting force without the high noise.

Eliminate Harmful Dead Ended Pressures

Air can be dangerous when the outlet pressure of a hole, hose or copper tube is higher than 30 PSIG (2 BAR). In the event the opening is blocked by a hand or other body part, air may enter the bloodstream through the skin, resulting in a serious injury. All of the Air Nozzles and Jets manufactured by EXAIR have been designed for safety. All are safe to be supplied with higher pressure compressed air and meet OSHA standard 29 CFR 1910.242(b).
