Air Amplifiers – Vent, Exhaust, Cool, Dry, Clean – With No Moving Parts!

Published on by Leave a comment

As an Application Engineer, one of the interesting aspects of working with customers on applications is the varied types of solutions an EXAIR product can provide.  The Air Amplifier family – Super Air Amplifier, Adjustable Air Amplifier, and the special High Temperature Air Amplifier can be used in a wide variety of process and applications.  Below highlights several of those from past experiences.

A defense contractor was performing maintenance service on a Navy ship, and the ventilation system had to be shut down.  To keep the personnel cool and safe, an auxiliary ventilation was to be supplied.  Rather than use a cumbersome blower assembly, which has to mounted on the top deck, and ducted down to the lower decks, they chose to utilize (2) 4″ Super Air Amplifiers.  They are very portable and can be set up in minutes.  This solution provided the necessary air flow, providing a safe environment for the maintenance crew.

Super Air Amplifier
EXAIR Air Amplifiers use a small amount of compressed air to create a tremendous amount of air flow.

A light bulb manufacturer needed a better solution for a cooling operation.  During manufacturing of a mercury lamp, the bulb must be cooled from 700°C to 600°C in just 15 seconds.  The current method, an open brass pipe, was working but the noise level was too high (95 dBA.) The goal was to maintain the 15 second cooling time, but reduce sound levels to 85 dBA.  By utilizing (2) of 3/4″ Adjustable Air Amplifiers, the customer was able to maintain the cooling rate, and reduce the noise level down to 80 dBA, a 15 dBA reduction.

A garbage collector presented a problem that needed a solution.  The garbage was incinerated and when the furnaces were first started up, there tended to be issues with getting the flue to draft properly.  Using the High Temperature Air Amplifier, the high velocity air flow and draw provided the needed draft until the stack warmed up and the natural draft would be established.  Since the unit is capable of handling temperatures up to 700°F, it was able to withstand the heat of the process after the compressed air was turned off.

These and other Applications for the Air Amplifiers and all other EXAIR products can be found on the EXAIR website on the Products page, under the Related Info section toward the bottom of each page.

Video Blog: Air Entrainment Of An Air Amplifier

The following is a short video explaining how EXAIR’s Super Air Amplifiers work. It also shows the high volume of surrounding air that is pulled into the outlet flow with a very small amount of compressed air required. As yo will see, this high volume of ambient air produces a dramatic effect on the Air Amplifier’s  outlet flow. Super Air Amplifiers are very efficient, quiet and safe and can be used to vent fumes, circulate air, cool, clean and blow off surfaces.

Need A Flange? We Can Do That!

I recently had a customer call in that was trying to boost an exhaust on a hot operation that he had in his facility.   We discussed what kind of fumes he was trying to evacuate and it appeared at face value that a High Temp Air Amplifier would be the perfect solution for his application.

A Model 121021 1-1/4" High Temp Air Amplifier directs hot air to a rotational mold cavity for uniform wall thickness of the plastic part.

Then the words that strike fear into some manufacturers came out.  The customer asks, do you have any way to put a 4 bolt flange onto the unit so I can mount it straight into my piping system?   My response, “All I need are the dimensions of the flange you need and we will see what is possible.”  After a few further questions and verification, we had a drawing  with dimensions of a Flanged High Temp Air Amplifier.  We sent the drawing to the customer for approval, and once approved, we began to manufacture the custom product and provided it to the customer.  This unit will allow the customer to easily boost the exhaust on his operation and will bolt straight into his piping so there are no worries on his end about exhaust gas escaping.  His 500°F air temperature of the gases are of no concern to this special as it carries with it the high temperature rating of 700°F.  The pictures below show the Special – Flanged High Temp Air Amplifier.

The O.D. of the flanges was 6″ with 4 – 3/4″: bolt holes. The Bolt holes were not required to align with the opposing side.

If you think there is no way we can find a product that will fit your compressed air application, or adapt a product to fit then give us a call, you might just be surprised at what we can offer in a quick turn around.

Stainless Steel Adjustable Air Amplifiers Replace Blower in Exhaust Hood Application

EXAIR Stainless Steel Adjustable Air Amplifiers model 6034

 

I was working with our Indonesian distributor the other day on an interesting application in the sugar refining industry.

The application was in a sugar refining plant. As the sugar cane is cooked down, the resulting gas vapor is pulled up through a vent hood and exhausted outside the building. The customer was using a 16” diameter blower to create the needed draft to draw the vapors. The problem is that the vapors are corrosive and sticky when cold. The effect is that the blower blade becomes caked with deposits which, in turn corrode the blade and it must either be cleaned and/or replaced at frequent and regular intervals.

The customer wanted to get away from having to deal with the blower issue if they can, so they turned to our distributor for ideas on how to solve the problem using EXAIR equipment. Turns out that a cluster of (3) model 6034 4” Adjustable Air Amplifiers operating at 5 BARG input pressure are able to generate the necessary flow to replace the blower in this system.

The keys to success in the application were the fact that the Adjustable Air Amplifiers are constructed of Stainless Steel to resist the corrosive effects of the gas vapor. Also, there isn’t any deposits on the blade that need to be dealt with. While cleaning of the Air Amplifiers is recommended in this application, the maintenance interval was able to be much longer between cleanings.

In many industrial applications, blower driven or electric motor driven equipment is usually preferred in an effort to save energy. This was a good example of a case where the quality of having no moving parts was able to offset other maintenance costs that made use of a blower actually more expensive for the user.
