EXAIR Super Air Amplifiers™ under 8" (203mm) are supplied with a .003" (0.08mm) slotted air gap which is ideal for most applications. The Model 120028 8" (203mm) Super Air Amplifier is supplied with a .009" (0.23mm) air gap. Flow and force can be increased by replacing the shim with a thicker .006" (0.15mm) or .009" (0.23mm) shim. Super Air Amplifier Shim Sets include (1) .006" (0.15mm) and (1) .009" (0.23mm) stainless steel shim (except Model 120028, which also includes (1) .015" (0.39mm) stainless steel shim).

Special Air Amplifiers
EXAIR will manufacture special Air Amplifiers suited to your specific application requirements. The Model 121021 High Temperature Air Amplifier was developed for moving hot air to surfaces requiring uniform heating while in a furnace or oven. Modeled 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 700°F (374°C) 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.
Another stainless steel version for flange mounting was developed as a fan back-up for exhausting flue gases from a furnace. In the event of a power failure, this special Air Amplifier can quickly evacuate the fumes that could be harmful to workers close by.
A PTFE plug was used with a stainless steel Adjustable Air Amplifier to help pull a sticky material through a process and prevent the material from depositing on the Air Amplifier.
EXAIR's Intelligent Compressed Air® products can be manufactured to your special requirements.
If you have special requirements, please contact an Application Engineer to discuss it.
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 60 PSIG (4.1 BAR) supply air pressure has a total output flow of 120 SCFM (3,398 SLPM). Air Consumption: Divide total output flow by the amplification ratio to determine air consumption for any Super Air Amplifier at any air pressure. In the example above, the Model 120021 at 60 PSIG (4.1 BAR) supply air pressure has a total output flow of 120 SCFM (3,398 SLPM). Dividing this total output flow by its amplification ratio of 18 gives an air consumption of 6.7 SCFM (189 SLPM). |
