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).

Super Air Amplifier Systems

Super Air Amplifiers are available in four different model types:

  • Super Air Amplifier Only
  • Super Air Amplifier Kits - include a Super Air Amplifier, shim set, filter separator and pressure regulator (with coupler).
  • Deluxe Super Air Amplifier Kits - include a Super Air Amplifier, EFC, shim set, filter separator and pressure regulator (with coupler).
  • Super Air Amplifier Shim Sets - include (1) .006" (0.15mm) and (1) .009" (0.23mm) stainless steel shims (except 8" which include (1) .015"(0.39mm) stainless steel shim).

Awards - Super Air Amplifier

1999 Plant Engineering Product of the Year Finalist

EXAIR's Super Air Amplifiers were a finalist in the 1999 Plant Engineering Product of the Year Awards. The Super Air Amplifier family placed in the Compressed Air category.

Special Air Amplifiers

Special High Temperature Air Amplifier Model 121021

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.

Special Flanged Air Amplifier

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.

Special Adjustable Air Amplifier with PTFE plug

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 DetermineSuper Air Amplifier Total Output Flow and Air Consumption

Total Output Flow - Super Air Amplifier

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).

Total Output Flow with 0.003" (0.08mm) thick shim installed. Excludes downstream entrainment. Model 120028 tested with a 0.009" (0.23mm) shim.
