What’s So “Super” About The Super Air Amplifier?

EXAIR Intelligent Compressed Air Products such as (left to right) the Air Wipe, Super Air Knife, Super Air Nozzle, and Air Amplifier are engineered to entrain enormous amounts of free air from the surrounding environment.

“Free air” from the surrounding environment?  You might think it’s too good to be true, and if you think you’re getting something for nothing, you’re right.  If you consider, though, that it’s oftentimes preferable to work smarter, not harder, then the use of engineered compressed air products is too good NOT to be true.  Case in point: the Super Air Amplifier.

The Coanda Effect is the “work smarter, not harder” part of the Super Air Amplifier

Simple and low cost, (hey, “engineered” doesn’t necessarily mean “complex and expensive”) the EXAIR Super Air Amplifier uses a small amount of compressed air to generate a tremendous amount of air flow through entrainment.  How much do they pull in?  Depending on the model, they entrain air at rates of 12:1 (for the 3/4″ Model 120020) to 25:1 (4″ & 8″ Models 120024 & 120028, respectively.)  The larger diameters mean there’s more cross sectional area to entrain air, so there is indeed efficiency to scale, size-wise.  There are a couple of great visuals in this video, if you want to see the entrainment in action (1:50) or the difference that the entrainment makes (1:30):

 

Where can you use a Super Air Amplifier?  The easy answer is, anyplace you want a consistent, reliable air flow.  The pressure supply can be regulated from a “blast to a breeze,” depending on the needs of your application.  The patented shim can be replaced for even higher performance, while maintaining the efficiency that makes it so valuable.  The balanced flow makes for incredibly quiet operation…no more noisy fans, blowers, or open-end compressed air pipes.  The body (3/4″ to 4″ sizes) is cast with a 2-hole flange for ease of installation.

When can you use a Super Air Amplifier?  Another easy answer: anytime you want.  If you need a continuous air flow, there are no moving parts to wear or electrical components to burn out.  Supply them clean, dry air, and they’ll run darn near indefinitely, maintenance free.

Alternately, if you need intermittent air flow, starting & stopping operation is as simple as opening & closing a valve in the compressed air supply line.  They produce rated flow immediately, and cut it off just as fast.

Some of the more popular applications are ventilation/exhaust, cooling, drying, cleaning, and dust collection.  There are five distinct models to choose from, and they’re all in stock.  We’re also happy to discuss special requirements that might lead to a custom product too.  Our Application Engineers work with Design & Production all the time to meet specific needs of particular situations.

If you’d like to find out more about letting the Super Air Amplifier, or any of EXAIR’s Intelligent Compressed Air Products work smarter for you, give me a call.

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.

More Power? I DO Think So…

We occasionally get calls from folks who are looking for “more power” – and it always brings that classic 1990’s sitcom “Home Improvement’s” Tim “the Tool Man” Taylor to mind. Well, not so much Tim’s “more power” mantra, but the ubiquitous response from his long-suffering sidekick, Al Borland:

Al knows it.  George Foreman knows it. Lisa knows it.  Even Tim knows it, this time.

Sometimes, they’re looking for a product to replace what they’re currently using…something they’re not getting desirable results from. Other times, they have an EXAIR product in place, and it’s just not getting the job done.

Our first response is, of course, to make sure they’re getting a sufficient supply of air to their product, no matter whether it’s ours or not. If you’re familiar at all with our blogs, you know we write about this frequently:

3 Common Mistakes in Your Compressed Air System

Once we’ve made sure that the product is indeed receiving appropriate air supply, we can look at adding to the flow rate and force of the air stream. We’ve made it easy to do that with a variety of blow off products by designing them with a replaceable shim.

All of our Air Knife products (Super, Standard, and Full Flow) will ship with a 0.002” thick shim installed. These will perform superbly in a wide variety of general industrial blow off applications. If this doesn’t provide the force needed for your application, we carry Shim Sets for any Air Knife that will allow you to double, triple, or even quadruple the air flow for amplified thrust. Some common examples are stubborn debris in tight spaces (like the fins of a fin-and-tube heat exchanger) or removing oil from a corrugated surface.

From left to right: Super, Standard, and Full Flow Air Knives.

 

Like the Air Knives, our Air Wipes (Super and Standard) are built with 0.002” thick shims, which can be easily replaced for additional flow and force. Like when the Air Wipe is getting all the coolant off an extruded & machined part, but some stubborn, hair-like fibers need a little more “oomph” to remove.

 

Super (left) and Standard (right) Air Wipes come in sizes from 1/2" to 11".

Yes, those were real calls I took. Yes, they had sufficient air flow. Yes, the extra shims worked like a champ.

Similar to our Air Knife products, our Flat Super Air Nozzles also incorporate a replaceable shim. In fact, you have your choice of standard Models with a 0.015” thick shim installed, or High Power Models with a 0.025” thick shim. Shim Sets with a variety of thicknesses from 0.005” to 0.030” are available for either of these.

Our Super Air Amplifiers and High Velocity Air Jets incorporate patented shims that make for the highest amplification flows available, anywhere. These are available, from stock, in Shim Sets or individually.

High Velocity Air Jets and Super Air Amplifiers use patented shims for optimum performance and efficiency.

If you have an air blowing application that you’d like to get a little (or a lot) more out of, give us a call. Prepare for a discussion on proper air supply first (of course,) but we’ll be more than happy to help in any way that we can.
