Air Amplifiers – Air Pressure or Air Flow Volume

Published on by EricKuhnash@EXAIR.comLeave a comment

When talking about Air Amplifiers there are two (2) kinds when considering what best fits your needs. An amplifier that is used to increase pressure above your compressor’s ability are also known as air boosters. These boosters are sometimes needed for specific processes which demand much higher pressures. Amplifiers that increases the volume flow rate of your compressed air or nitrogen are the type of amplifier that EXAIR manufactures. 

EXAIR’s Super Air Amplifiers will increase the volume of air on to a target or being circulated in an environment. EXAIR’s Air Amplifiers use the Coanda effect pulling in large volumes of surrounding air to produce high volume, high velocity outlet flows up to 25 times their consumption rate.

Air Amplifiers have no moving parts and are basically maintenance free. EXAIR’s amplifiers operate on a source of clean compressed air and do not use electricity. The outlet flows are easily adjusted by opening or closing the air gap. By regulating the supply pressure you can tune in your outlet flow to meet your specific needs. Vacuum and discharge ends of the Air Amplifier can be ducted, making them ideal for drawing fresh air from another area or for moving smoke and fumes away.

Super Air Amplifier Family

EXAIR has 5 standard sized Air Amplifiers ranging from 3/4″ (19mm) to 8″ (203mm) plus an Adjustable Air Amplifier . If you have a specific application EXAIR can manufacture Air Amplifiers to fit your application. If you have a project and think EXAIR’s Air Amplifier or any of our Intelligent Compressed Air Products please contact me or any of our qualified Application Engineers to discuss your project.

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

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.

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.

Stainless Steel Adjustable Air Amplifiers Replace Blower in Exhaust Hood Application

Vent hood
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.
