Understanding EXAIR Air Amplifiers and Air Pressure Amplifiers

Adjustable Air Amplifier

I take many calls regarding Air Amplifiers but sometimes I get calls that confuse EXAIR Air Amplifiers with air pressure amplifiers. EXAIR’s Air Amplifiers and air pressure amplifiers are fundamentally different and have different purposes.

First, EXAIR’s Super Air Amplifiers and Adjustable Air Amplifiers increase air volume, not pressure. Air pressure amplifiers increase air pressure from typical system pressure of 80-130PSIG up to 5000 PSIG. Air pressure amplifiers are an excellent solution for applications that require higher air or nitrogen pressure such as increasing force for clamps or presses and pressure testing processes. They are also known as air boosters.

Air Amplifiers use the Coanda Effect to generate high flow with low consumption.

EXAIR Air Amplifiers are a low cost way to move air, smoke, fumes and light materials. These Air Amplifiers use the Coanda effect to create a low pressure area which draws in surrounding air to efficiently deliver a high volume of air on to a target. Using a small amount of compressed air as their source, Air Amplifiers are among the most efficient products within EXAIR’s entire product line. EXAIR Air Amplifiers will create output flows up to 25 times their consumption rate and deliver it at a high velocity. The entrainment of outside air amplifies the total volume of air output which also increases force, cooling ability and circulation.

EXAIRs Air Amplifiers have no moving parts, assuring maintenance-free operation. Fine tuning flow, vacuum and velocity are easily controlled by regulating the pressure. For gross adjustment of air flow and vacuum an internal shim is used to increase or decrease the internal “air gap” that the compressed air flows through. Both 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.

I hope this helps distinguish EXAIR Air Amplifiers versus air pressure amplifiers. If you have questions regarding EXAIR Intelligent Air Products please contact one of our Application Engineers as we are always ready to help.
