High Temperature Air Amplifier

High Temperature Air Amplifiers are rated to withstand temperatures up to 700°F (374°C) and are designed for air circulation in hot environments such as ovens, furnaces, and large molds. By leveraging the Coanda effect—a fundamental principle of fluidics—these Air Amplifiers offer an affordable and straightforward solution to circulate air, move smoke, fumes, and lightweight materials. Powered by a small amount of compressed air, they draw in large volumes of surrounding air to produce high-volume, high-velocity outlet flows through a fixed air gap. These devices are not only quiet and efficient but also capable of generating output flows up to 25 times their consumption rate.

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.
