Super Air Amplifier™
Powerful, efficient and quiet air mover for blowoff, cooling and ventilation
A combination of Model 120022 2″ (51mm) Super Air Amplifiers and Model 1122 2″ Super Air Nozzles blowoff transmissions after they are machined.
What is the Super Air Amplifier?
Super Air Amplifiers have the highest amplification ratios and are the most efficient of all Air Amplifiers. The patented* design uses a special shim to maintain a critical position of the component parts. As a result, a precise amount of compressed air is released at exact intervals toward the center of the Super Air Amplifier. These jets of air create a constant, high-velocity outlet flow across the entire cross-sectional area. Additional free air is pulled through the unit, resulting in higher amplification ratios. The balanced outlet airflow minimises wind shear to produce sound levels that are typically three times quieter than other Air Amplifiers.
Super Air Amplifiers are supplied with a .08mm (.003″) slotted air gap which is ideal for most applications. Flow and force can be increased by replacing the shim with a thicker 0.15mm (.006″) or 0.23mm (.009″) shim. Model 120028 is supplied with a 23mm (.009”) air gap. A .39mm (0.15”) shim is available for Model 120028.
†Patent #5402938
High Temperature Air Amplifier
The Model 121021 High Temperature Air Amplifier was developed for moving hot air to surfaces requiring uniform heating while in a furnace or oven. Modelled after our Super Air Amplifier, the High Temperature Air Amplifier is the most efficient for pushing high volumes of hot air to points that typically remain cool. This special design is rated for environments up to 374°C (700°F) and its surface is protected from heat stress by a mil spec. coating process (developed for the aircraft industry), allowing easy disassembly for changing shims or cleaning.

How To Determine Super Air Amplifier Total Output Flow And Air Consumption
Total Airflow:
From the performance curves (above), determine total output flow for any Super Air Amplifier at any pressure.
Example:
A Model 120021 at 4.1 BAR (60 PSIG) supply air pressure has a total output flow of 3,398 SLPM (120 SCFM).
Air Consumption:
Divide total output flow by the amplification ratio (shown in the table above) to determine air consumption for any Super Air Amplifier at any air pressure.
In the example above, the Model 120021 at 4.1 BAR (60 PSIG) supply air pressure has a total output flow of 3,398 SLPM (120 SCFM). Dividing this total flow by its amplification ratio of 18 gives an air consumption of 189 SLPM (6.7 SCFM).

EFC Electronic Flow Control
Turn off the compressed air when it isn’t needed
EXAIR’s EFC™ is a user-friendly electronic flow control for compressed air that is designed to minimise compressed air use on blowoff, drying, cooling, conveying and static elimination operations. The EFC combines a photoelectric sensor with a timing control that limits compressed air use by turning it off when no part is present. The timing control permits easy tuning to the application requirements while providing flexibility in sensing distance.

With proper filtration of dirt, moisture and oil from the compressed air supply, EXAIR compressed air products will operate for years with no maintenance required. Use a 5 micron or smaller filter separator on the compressed air supply. To prevent problems associated with oil, use a 0.03 micron or smaller oil removal filter on the compressed air supply. Pressure regulators permit easy selection of the operating pressure, providing infinite control of flow, force and air consumption.
