Adjustable Air Amplifier

Highly effective air mover that easily adjusts to your application!


Adjustable Air Amplifier - have the same advantages as EXAIR's Super Air Amplifiers with the extra benefit of being infinitely adjustable. Ideal for work areas with constantly changing conditions.

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. 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. 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.

What is The Adjustable Air Amplifier?

The air gap is infinitely adjustable which regulates the consumption and outlet flow from a "breeze" to a "blast". They are available in aluminum or in stainless steel for food service, higher temperatures (400ºF/204ºC), and corrosive applications. High Temperature Stainless Steel Air Amplifiers for temperatures up to 700ºF (374ºC) are also available. Please contact us.

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. In most case, a .002" to .004" (0.05mm to 0.10mm) air gap is ideal.

Advantages:

Compare to Fans:

  • 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 Super 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.

Here are some sample of applications:

Model 6042 2" (51mm) Adjustable Air Amplifier with swivel fittings cool inductively heated axles prior to installing the hubs.

 

A Concentrated blast of hot air is produced when an in-line heater is added to a Model 6031 1-1/4" (32mm) Stainless Steel Adjustable Air Amplifier.
