Adjustable Air Amplifier

Highly effective air mover that easily adjusts to your application!

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

What Is The Adjustable Air Amplifier?

Utilising 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. The air gap is infinitely adjustable, which regulates the consumption and outlet flow from a “breeze” to a “blast”. They are available in aluminium or in stainless steel for food service, higher temperatures (204°C/400°F), and corrosive applications.
High Temperature Stainless Steel Air Amplifiers for temperatures up to 374°C (700°F) are available.

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 cases, a .002″ to .004″ (.05mm to .10mm) air gap is ideal.

How To Determine Adjustable Air Amplifier Total Output Flow And Air Consumption

chart
Total Airflow

From the performance curves (above), determine total output flow for any Adjustable Air Amplifier at any pressure.

Example

A Model 6031 at 4.1 BAR (60 PSIG) supply air pressure has a total output flow of 4,672 SLPM (165 SCFM).

Air Consumption

Divide total output flow by the amplification ratio (shown in the table above) to determine air consumption for any Adjustable Air Amplifier at any air pressure.

In the example above, the Model 6031 at 4.1 BAR (60 PSIG) supply air pressure has a total output flow of 4,672 SLPM (165 SCFM). Dividing this total flow by its amplification ratio of 16 gives an air consumption of 292 SLPM (10.3 SCFM).

Applications

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

Advantages

Compared to Fans :
  • Compact, lightweight, portable
  • No electricity
  • No moving parts – no maintenance
  • Ends are easily ducted
  • Instant on/off
  • Variable force and flow
  • No RF interference

Compared to Venturis and Ejectors:
  • More air volume with lower compressed air consumption
  • Higher flow amplification
  • No internal obstructions
  • Meets OSHA pressure and noise requirements
  • Quiet

A series of Adjustable Air Amplifiers dry and cool a large machined casting as it exits a high-temperature wash.

Metal parts are tried using a series of Model 6042 2” (51mm) Adjustable Air Amplifiers.

Adjustable Air Amplifiers and High-Velocity Air Jets dry an engine block prior to assembly.

Adjustable Air Amplifiers are ducted to draw clean air for drying.

EFC Electronic Flow Control
Turn off the compressed air when it isn’t needed

EXAIR’s EFC™ is a user-friendly electronic flow control for compressed air that is designed to minimise compressed air use on blowoff, drying, cooling, conveying and static elimination operations. The EFC combines a photoelectric sensor with a timing control that limits compressed air use by turning it off when no part is present. The timing control permits easy tuning to the application requirements while providing flexibility in sensing distance.

Filters, Regulators, Valves & More

With proper filtration of dirt, moisture and oil from the compressed air supply, EXAIR compressed air products will operate for years with no maintenance required. Use a 5 micron or smaller filter separator on the compressed air supply. To prevent problems associated with oil, use a 0.03 micron or smaller oil removal filter on the compressed air supply.  Pressure regulators permit easy selection of the operating pressure, providing infinite control of flow, force and air consumption.
