Force and flow for the Adjustable Air Amplifier is changed by turning the exhaust end (with the knurled ring loose) to open or close the continuous air gap. When desired performance is obtained, the knurled ring can be tightened to lock the flow at that setting. Utilizing a basic principle of fluidics, the Coanda effect, Air Amplifiers become a simple, low cost way to circulate air, move smoke, fumes, and light materials. Available in aluminum or in stainless steel for food service, higher temperatures (400°F/204°C), and corrosive applications. Custom materials, mounting options (flanges) and sizes available.
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.
