HomeAir Amplifiers “move air”!   Air Amplifiers entrain air utilizing a small amount of compressed air producing “amplifies air flow” for blow off, cleaning and cooling.   In addition to a significant reduction in energy use, air amplifiers reduce exhaust noise levels significantly.

Nex FlowTM Air Amplifiers can also be used to vent fumes and dust.   They are light weight and portable for easy installation and use, Fixed standard versions are available in rugged cast zinc/aluminum.   Adjustable air amplifiers are available in anodized aluminum or stainless steel.

A common application for air amplifiers is to cool large parts using the “wind chill effect”.  The high velocity, amplified air flow cuts through the boundary layer produced by the heat radiated from a hot part and takes away the heat to cool the part significantly faster than what can be done with a blower.

Venting fumes is popular with air amplifiers because the move a large volume of air and are portable, light weight, and easily installed.

And of course air amplifiers are ideal for blow off applications, especially when the annular output is to an advantage.  For example, the 1-1/4” air amplifier is a perfect fit to blow off water from soda cans on a conveyor line.  As the can move along, even at high speed, the air flow patter scoops out the liquid at the top of cans, leaving them dry to be able to ink jet the date stamp into the can.

When using compressed air for blow off, the shape of the part, and speed of the part determines which type of amplifier needs to be used – whether it is a regular air amplifier or a nozzle, jet or air knife.

A great feature of air amplifiers and air amplifier technology is that they have no moving parts and if the air is kept clean, can basically last a lifetime.   The profile on the air amplifier (whether a standard unit or an air knife version, or jet or nozzle) achieve this air amplification (which is really a conversion of pressure into useful flow instead of losing it in the form of pressure drop and noise) is generally a “coanda” profile which over time may get deposits forming on it.  These deposits need to be cleaned off occasionally to keep the profile effective.  Also, the compressed air should be filtered properly to remove moisture, oil and dirt.  Our recommendation is to filter moisture to at least 10, or better yet, 5 micron and filter oil if any in the air lines to 0.3 micron.  With proper filtration and cleaning of the coanda surface, air amplifiers can work indefinitely.

When using air amplifiers for cooling, you can cool to near ambient temperature only which is adequate for most applications.  If the cooing requirement is such that you need to lower the temperature below ambient, you can add a hose or pipe to an annular air amplifier and drawing in cooler air from outside of the area.   However care must be made that the back pressure created by adding the attachment does not reduce the air amplification too much as these units are sensitive to back pressure.   In this case the attached hose or pipe should be kept large in diameter and minimize the length and bends.

A big advantage of compressed air amplifiers of any type is that they can be turned on and off almost instantly.  When they do not need to blow, clean, cool, or vent they can be easily shut off using sensors and turned on again when needed.  On off operation can save a great deal of energy.

Safety is a big feature with air amplification technology because no electricity is used.

The concept of air amplification is sometimes abused.  When you convert pressure to flow, you do get amplified output air flow.  But claims from different manufacturers range from reasonable to the ridiculous.   Recognize that when the flow is amplified, it is done so by drawing in “still” air from its surroundings.  As that still air starts to move, overall velocity will slow down.  The more you draw in (or amplify more), the less the velocity.  So when claims are made that seem rather high in air amplification, make sure it is reasonable.   For example, if an annular air amplifier from one source amplifies 15 times at its exit and from another the claim is 25 times, but the units look very much alike – who is correct?  The fact is that the unit which claims 25 times would have a significantly lower velocity.  You would get large volume but little force, negating any effective blow off and cooling due to low velocity.  Or, it could just be an unrealistic claim.  If it looks or sounds unrealistic, it probably is.   If one air knife company claims 25 times amplification and another 50 times, again get an explanation and clarification.   Ask yourself, “does It meet the rules of physics”.
