EXAIR Super Air Amplifiers – Circulate, Blow, Dry, Cool, Vent

Super Air Amplifier

EXAIR manufactures a volume-type amplifier called the Super Air Amplifier. Not to be confused with its cousin, the pressure-type amplifier which increases air pressure, these devices increase the volume of air. This is a great benefit for circulating, cooling, blowing, drying and transferring materials like smoke fumes or lightweight items. With a range of applications, the EXAIR Super Air Amplifiers can be a simple solution for your company.

Super Air Amplifier – flow region

Why an EXAIR Super Air Amplifier? Like a fan, they are designed to move air. But fans use motors and blades to push the air toward the target. The fan blades “slap” the air which creates turbulent air flows and loud noises. The Super Air Amplifiers does not have any blades or motors to move the air. It just uses a Coanda profile and a patented shim to create a low pressure to draw in the air. With physics, it is much easier to pull than it is to push. The method in pulling air through the Super Air Amplifier makes a more efficient, uniform, and quiet operation to blow air.

How It Works

To expand, Coanda was named after a Romanian aerodynamic pioneer, Henri Coanda where he found a fluid flow phenomenon. He stated that “a jet of fluid emerging from an orifice to follow an adjacent flat or curved surface and to entrain fluid from the surroundings so that a region of lower pressure develops” (1). Since air is a fluid, it will react in the same way. The EXAIR Super Air Amplifiers create a high velocity air stream along an engineered profile. So, as the air “hugs” the profile, a low pressure is created which will draw in ambient air. The ratio between the volume of air produced compared to the volume of compressed air needed is called the amplification ratio. The higher the ratio, the more efficient the blowing device is. With the EXAIR Super Air Amplifiers, we can reach amplification ratios up to 25 to 1.

Super Air Amplifier Family

EXAIR manufactures and stocks five different sizes ranging from ¾” (19mm) up to 8” (203mm) in diameter. One of the unique features with the Super Air Amplifiers is that the inlet and outlet can be ducted for remote positioning. They are very compact and can fit into tight places. They do not have any moving parts to wear, or need electricity to run; or require any maintenance. They only need clean compressed air to work. One of the unique features of the EXAIR Super Air Amplifier is the patented shim which optimizes the low-pressure to draw in more ambient air. For extracting welding smoke, increasing cooling capacities, and moving material from point A to point B; the more air that can be moved, the better the performance. And the patented shim inside the EXAIR Super Air Amplifiers provides that. As an added bonus, they are OSHA compliant for safety and meet the standards for noise level and dead-end pressure.

Patented Air Amplifier Shims

EXAIR offers the Super Air Amplifiers in kits for a more complete system. The kit will include a filter separator, a pressure regulator and a Shim Set. The filter can remove debris and water from the compressed air line to keep the Super Air Amplifier and your product clean. The regulator is used to make “fine” adjustments to the blowing volume while the Shim Set is used as a “coarse” adjustment. The Shim Set includes different thicknesses of shims to set the gap. The Super Air Amplifiers come standard with a 0.003” (0.08mm) thick shim for the sizes ¾” (19mm) up to 4” (102mm), and a 0.009” (0.23mm) thick shim for the 8” (203mm) size. The Shim Set will include (1) 0.006” (0.15mm) and (1) 0.009” (0.23mm) shim for the models 120220 through 120224 or (1) 0.015” (0.39mm) shim for the model 120228. EXAIR sells these kits as one model number for simple ordering and for proper sizing of the accessories to not hinder the performance of the Super Air Amplifiers.

120224DX

To optimize the system even more, EXAIR also offers a Deluxe Kit for the Super Air Amplifier models. This will include the accessories in the kit above, plus an Electronic Flow Control, or EFC. This exclusive instrument uses a photoelectric eye to start a timing sequence to control a solenoid valve. So, when a part is not in front of the Super Air Amplifier, the compressed air is turned off. This will save you even more money and maximize your efficiency to only blow air when needed. They can be ordered with the kits by placing a “DX” at the end of the model number, such as 120224DX.

With the today’s cost to make compressed air, it is important to use it as efficiently as possible. The EXAIR Super Air Amplifiers have the ability to give effective blowing to remove debris, dry parts, transport material, or cool objects without using a large amount of compressed air. EXAIR has the Super Air Amplifiers in stock and as always, EXAIR offers a 30-day unconditional guarantee for our customers in the U.S. and Canada to try them out. If you have any questions about the Super Air Amplifiers or if you would like to discuss your application, an Application Engineer at EXAIR will be happy to help you.

Super Air Nozzles and Stay Set Hoses to Replace Open Tubes

I recently worked with an company that performs energy audits and they were working with a food company to review and propose ways to reduce the energy consumption throughout the plant. One area where we were able to help was on an onion peeling machine, shown below:

Vegetable Peeler Wide
Onion Peeler With Screw Conveyor and Blow off Tubes

The area of machine in question used a screw conveyor and friction source to help loosen the peels and fifteen (15) 1/4″ O.D. open ended tubes, which were noisy and unsafe, to blow the peels completely off and away form the onion. The auditor was able to install an air flow meter on the system and found that the machine was consuming 220 SCFM of compressed air for this operation.

Vegetable Peeler Detail
(15) Total, 1/4″ Tubes Used to Blow Air and Help Remove the Peels

We proposed to replace the tubes with a 6″ Stay Set Hose and the model 1103 Mini Super Air Nozzle.  Each model 1103 Mini Super Air Nozzle will consume just 10 SCFM of 80 PSIG compressed air. Attached to the 6″ Stay Set Hose, the nozzle can be placed exactly where needed and aimed appropriately. A strong blast of air rated at 0.56 lbs (9 ozs.), and ultra quiet at 71 dBA, the Mini Super Air Nozzle delivers the results needed.

Model 9256 6″ Stay Set Hose

The Stay Set Hose has “memory” and will not creep or bend, simply install the 1/4 NPT fitting into the compressed air supply side, an thread the 1/8 NPT Mini Super Air Nozzle into the other end and position as needed!

Fifteen (15) of the Mini Super Air Nozzles will pass 150 SCFM of compressed air compared to the current usage of 220 SCFM, resulting in a 70 SCFM drop, or a 31.8 % reduction.  At a typical cost of $0.25 per 1000 Cubic Feet of Compressed Air, the nozzles would save $1.05 per hour of operation. Rate of Return yields a full pay-off in just 43 days of operation (24 hours per day operation)!

If you are looking for ways to save on compressed air usage in your facility that is safe to operate and quiet to use, we will have a solution for you.

The Vac-u-Gun can be used in three modes- Vacuum, Transfer and Blowoff-

Vacuum Mode – Vacuum shavings, absorbents, sawdust, or spills into a reusable bag, or into a receptacle via the vacuum hose. Why blow it off and the have to sweep it up later?

Transfer Mode – Transfer small parts, pellets, or trim over long distances, using the smooth bore vacuum hose.

Blowoff Mode – Blow chips, water, coolant, or scrap away from the work area. The large 1-1/4″ diameter outlet directs the air over a larger area in less time. The Vac-u-Gun uses less compressed air than an ordinary blow gun.

Vac-U-Gun Specifications

There are many advantages to a Vac-u-Gun, and some are:

Low cost, no moving parts/maintenance free, durable die cast construction, easy to switch form vacuum to blow mode, safe – no electricity, meets OSHA pressure requirements, lightweight and portable, versatile, and quiet.
