High Temperature Air Amplifier

Ideal for moving hot air to surfaces requiring uniform heating in ovens and furnaces.


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. Using a small amount of compressed air as their power source, High Temperature Air Amplifiers pull in large volumes of surrounding air to produce high volume, high velocity outlet flows through a fixed air gap. Quiet, efficient Air Amplifiers will create output flows up to 25 times their consumption rate.

Advantages:

Compare to Fans:

  • Works in temperatures up to 700°F (371°C)
  • No Moving Parts and no electricity required
  • Ends are easily ducted
  • Instant On/Off
  • Variable force and flow
  • No RF interference

Compared to Venturies and Ejectors:

  • More air with lower compressed air consumption
  • Higher flow amplification
  • No internal obstructions
  • Meets OSHA pressure and noise requirements
  • Quiet

Applications:

  • Vent welding smoke
  • Cool hot parts
  • Dry wet parts
  • Clean machined parts
  • Distribute heat in ovens/molds
  • Ventilate confined areas
  • Dust collection
  • Exhaust tank fumes

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.

Sample of application:

A Model 121021 1-1/4" (32mm) High Temperature Air Amplifier directs hot air to a rotational mold cavity for uniform wall thickness of the plastic part
