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, EXAIR's 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.

The High Temperature Air Amplifier is available in five standard outlet diameter of 3/4", 1-1/4", 2", 4" and 8" (19, 32, 51, 102 and 203mm) and produce air volume at outlet up to 3.000 SCFM (84.900 SLPM).

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.
