What are Air Amplifiers?

A simple, low cost way to move air, smoke, fumes, and light materials. Air Amplifiers utilize the coanda effect, a basic principle of fluidics, to create air motion in their surroundings. Using a small amount of compressed air as their power source, Air Amplifiers pull in large volumes of surrounding air to produce high volume, high velocity outlet flows. Quite, efficient Air Amplifier will create output flows up to 25 times their consumption rate.

Why Air Amplifiers?

Air Amplifiers have No Moving Parts, assuring maintenance-free operation. No electricity is required. Flow, vacuum and velocity are easy to control. Outlet flows are easily increased by opening the air gap. Supply air pressure can be regulated to decrease outlet flow.

Both the vacuum and discharge ends of the Air Amplifier can be ducted, making them ideal for drawing fresh air from another location, or moving smoke and fumes away.

Applications:

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

Advantages:

Compare to Fans:

• Compact, lightweight, portable
• No Moving Parts - no maintenance
• 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

How 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.

Featured Products:

• Super Air Amplifier, powerful, efficient and quiet air mover for Blowoff, Cooling and Ventilation.
• Adjustable Air Amplifier, highly effective air mover that easily adjusts to your application.
• High Temperature Air Amplifier, ideal for moving hot air to surfaces requiring uniform heating in ovens and furnaces.
• Stainless Steel Adjustable Air Amplifier, highly effective air mover made of Stainless Steel that easily adjusts to your application

Special Air Amplifiers

EXAIR will manufacture special Air Amplifiers suited to your specific application requirements. The Model 121021 High Temperature Air Amplifier was developed for moving hot air to surfaces requiring uniform heating while in a furnace or oven. Modeled after our Super Air Amplifier, the High Temperature Air Amplifier is the most efficient for pushing high volumes of hot air to points that typically remain cool. This special design is rated for environments up to 700°F (374°C) and its surface is protected from heat stress by a mil-spec. coating process (developed for the aircraft industry), allowing easy disassembly for changing shims or cleaning.

Another stainless steel version for flange mounting was developed as a fan back- up for exhausting flue gases from a furnace (shown middle right). In the event of a power failure, this special Air Amplifier can quickly evacuate the fumes that could be harmful to workers close by.

A PTFE plug was used with a stainless steel Adjustable Air Amplifier (shown bottom right) to help pull a sticky material through a process and prevent the material from depositing on the Air Amplifier. EXAIR's Intelligent Compressed Air® products can be manufactured to your special requirements.
