A Super Air Amplifier™ pulls 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 fluid dynamics, 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 It Works

How Air Amplifiers Work

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.
