View More
Super Air Amplifiers pull in large volumes of surrounding air using a small amount of compressed air to produce high volume, high velocity outlet flows through a fixed air gap. Utilizing the Coanda effect, a basic principle of fluidics, Air Amplifiers become a simple, low cost way to circulate air, move smoke, fumes and light materials. They are also effective as a blower to cool, clean and dry parts or processes and in workstation dust collection applications. Quiet, efficient Super Air Amplifiers will create output flows up to 25 times their consumption rate. Both the vacuum and discharge ends of the Air Amplifier can be ducted, making them ideal for drawing fresh air from another location, or moving smoke and fumes away.

How Air Amplifiers Work

How the Air Amplifier Works

Compressed air flows through the air inlet (1) into an annular chamber (2). It is then throttled through a small ring nozzle (3) at high velocity. This primary airstream adheres to the Coanda profile (4), which directs it toward the outlet. A low pressure area is created at the center (5), inducing a high volume flow of surrounding air into the primary airstream. The combined flow of primary and surrounding air exhausts from the Air Amplifier in a high volume, high velocity flow.

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 Determine Super 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.
