Air Amplifiers are amazing tools that pack a punch (if the punch is a ton of air flow). Imagine an amplification rate up to 25 times. You supply 29 SCFM and yield 730 SCFM coming out? It’s incredible. These little beauties work by flowing compressed air (80psig) through the inlet to the annular chamber. It is then throttled through a small ring nozzle at a high velocity. This Airstream employs the Coanda profile directing all this air to the outlet. Although you should never blow air at a person, a little bit of air input, would easily produce the results to the right!
Why would you use these? See below for starters:
Although we have many options to choose from, sometimes you may need something outside the box. Maybe it’s a different size? A different Material? A different fitting? Ask us we do have many ways to customize this product. Here are 3 examples of things we have done in the past.
The High Temp Air Amplifier (right) was developed for moving hot air to surface needing uniform heating while in a furnace or oven. This is designed for temps up to 700°F, and is now a standard offering in 1 1/4″.
Another example of a “Special” Air Amplifier is a stainless steel version with a flange mount (left). This was designed for exhausting flue gases from a furnace. If there were a power failure, this Special Air Amplifier will quickly evacuate harmful fumes, prior to affecting the workers.
A third “Special” was made when we were brought an application that required a sticky material to be pulled through the Air Amplifier, and it was unable to stick to the inside of the Amplifier. So we developed an Adjustable Air Amplifier with e PTFE Plug (Right), so the material would not stick.
If you have an application that requires a tool that is not quite in line with what we offer, don’t hesitate to reach out. I can’t promise you that we will be able to make it for you, but I can promise you that we will look at it and give it our best shot.

EXAIR’s product line contains many products that can be used for cooling. The focus of this blog will be Super Air Amplifiers. These often times get placed in a head-to-head competition with an electric fan. The best part, they easily come out on top.
When looking at the benefits other than performance and rate of cooling due to air entrainment, many customers prefer the Super Air Amplifier due to the fact there are no moving parts. This comes into play when cooling within in a hard-to-reach area or within a harsh process is needed. Placing an electric motor with a blade held on by fasteners may not be desirable from a maintenance standpoint. The Super Air Amplifiers do not require electricity and there is not a motor or bearings that would need to be replaced or inspected.
Another benefit is the small footprint of the Super Air Amplifier. This can also be seen within the video below where the Air Amplifier is shown is able to produce 341 SCFM (9,650 SLPM) in amplified airflow. Compared to the fan in the video, the amplifier is less than a 1/4 of the size but outperforms the fan in cooling the metal block! This allows users to place a small unit inside a tight area or chamber that requires large volumes of air. For instance, a rotomolded part that has a large chamber, and it needs surfaces to be cooled in order for the part to hold its shape from the mold rather than warp. This can also be coupled with the fact that a Super Air Amplifier can be ducted on either the suction or discharge side in order to retrieve cool air or move the warm air out of the area.
Speaking of warm, the Super Air Amplifiers are also manufactured to withstand up to 275 °F (135 °C) from stock. Stainless Steel and High-temperature models go well beyond that temp, up to 700 °F (374 °C). Custom-designed (flanges and different materials are common) versions are also available with short lead-times.

Throughout my years I have been in many manufacturing facilities. Oddly enough, I have seen nearly every part of a passenger car manufactured and then fully assembled. The amount of compressed air applications in automotive supplier and manufacturing facilities are tremendous. Here are some stories from just a few we have encountered over the years, and all of them can be found in our Application Database.
A component manufacturer, specifically a steering and transmission component manufacturer was having issues with machined parts coming out of a CNC machine with too much oil based cutting fluid on them and not passing inspection process because the oil would throw off the automated measuring system. The part was a splined shaft that the high surface tension oil stayed in the splines. The part was removed from the machine via robotic loader and set onto a fixture. The path to the fixture was outfitted with a Super Air Wipe so the robotic loader could move the part into and out of the air wipes’s airflow and remove the oil. The converging airflow of the Super Air Wipe was ideal to keep the peaks and valleys of the shaft clean of oil and they were able to direct oil back into the cutting machine so no separate collection system was needed.
2. A seat bracket manufacturer had issues protecting the lenses on their vision systems from welding spatter. They were again able to reduce the replacement / repair downtime by installing a 9″ Super Air Wipe in front of the robotic mounted lens and keep the spatter / fumes from ever making it to the lens, resulting in expanded run times between repair / downtime.
3. A forging company manufacturing the pistons was having issues reducing the temperature of the pistons as they were assembled to the connecting rods. The solution for them was to install a series of Super Air Amplifiers over the fixtured, indexing line and at each dwell station a Super Air Amplifier would activate and cool down the assembly by moving large volumes of ambient air mixed with small amounts of compressed air onto the surfaces.
4. An automotive manufacturer had issues with stamping shavings and welding debris staying on the surface of parts and fixtures resulting in rework and defective parts. Implementing a series of Super Air Nozzles, and Super Air Knives resulted in debris removal that saved tooling rework as well as production reject parts.
5. Another automotive / recreational vehicle manufacturer needed help with their torture test machine for suspension components. They were utilizing fans to try and keep shock sensors cool and replicate air movement. electric fans were not able to provide a focused airflow and so enter the Super Air Amplifiers. These have also been utilized on engine torture test machines.
These are just a select few of the actual applications that I have actually help with over the course of the years. As a whole, we have helped endless number of automotive industry applications. It doesn’t matter if you are in the automotive industry or just a garage tinkerer, contact and Application Engineer and let us help you with your point of use compressed air application today.
Air Amplifiers are a perfect solutions for utilizing air for Venting, Exhausting, Cooling, Drying, or Cleaning with no moving parts. As the name implies, these tools produce a high volume and a high velocity of outlet flow. These are very quiet, efficient and can amplify your air consumption up to 25 times… Here is a great diagram and description of exactly how these work:
As you can see, these fine pieces of engineering genius have no moving parts, and require no electricity. You can easily control the flow, force and velocity by opening or closing the air gap (fixed with a shim) and regulating the the supply air. These can also be ducted on each end to either pull in or remove air or fumes from one room or area to another.
SUPER?? What makes our Super Air Amplifier super? I’m glad you asked. The Super Air Amplifier has a patented design that uses a special shim to maintain critical position of the component parts. This results in a precise amount of compressed air to be released at exact intervals towards the center of the Super Air Amplifier. These jets of air create a constant, high velocity outlet flow across the entire cross-sectional area. This balances out the airflow to maximum performance, this simultaneously minimizes wind shear, causing sound levels up to 3 x’s quieter than other comparable air movers. To completely understand how much air this Super Air Amplifier amplifies (try saying that fast 5 times), please see the below chart.
As you can see, the amplification ratio is between 12 and 25 x the amount of air consumed. For the right applications, these are game changers… Pro tip – notice that even the highest level still falls under OSHA guidelines for noise!!
