Super Air Amplifiers – Adjustability for Blowoff, Drying, Cooling, Circulation and Ventilation

The Super Air Amplifier is a powerful, efficient, and quiet air mover. Applications currently in place include blowoff, drying, cooling, circulation and ventilation. Sizes from 3/4″ to 8″ are available to best match the air volume that is necessary to achieve the process goals. There are a couple of ways to change the performance of the Super Air Amplifier if either a small or large change to the output flow is required.AirAmplifiers

The chart below shows the Total Output Flow for each of the 6 models. As an example, the Model 120021 or 121021, when operated at 60 PSIG of compressed air supply, will have a total output flow of 120 SCFM. These same devices when operated at 80 PSIG will have a total flow of 146 SCFM. By simply using a pressure regulation device on the compressed air supply, the output performance can be tuned to match the desired outcome.

Capture

For those applications where much greater flow and/or force is needed, the option of installing a thicker shim is available.  The Super Air Amplifiers are supplied with a 0.003″ shim installed (the 8″ model 120028, has a 0.009″ shim as standard) and can be fitted with shims of thicknesses of 0.006″ or 0.009″ (the 8″ model has an optional 0.015″ shim.) Installation of a thicker shim increases the slotted air gap, allowing for a greater amount of controlled air flow.  As a general rule, doubling the shim thickness will double the air flow rates.

Super Air Amplifier Shims
Patented* Shim Design for Super Air Amplifiers

The Super Air Amplifier design provides for a constant, high velocity outlet flow across the entire cross sectional area,.  The balanced outlet flow minimizes wind shear to produce sound levels that are typically three times quieter than other air movers. By regulating the compressed air supply pressure and use of the optional shims, adjustability and flexibility of the unit is wide ranging and sure to meet your process needs.

Super Air Amplifiers vs. Fans – Why are Amplifiers More Effective at Cooling & Drying?

Super Air Amplifier
Super Air Amplifiers entrain ambient air at a rate of 25:1!!

When seeking a suitable solution for cooling or drying your parts, you may be tempted to try out a low-cost fan to get the job done. While fans do a great job of keeping you cool during the warmer months, they’re not the best choice for cooling or drying parts. Have you ever noticed that when standing in front of a fan the flow pattern is not consistent? This is due to the nature in which the fan blades create that air flow by “slapping” the air as they spin rapidly. The air flow that exits from the fan is turbulent and is not as effective as the laminar air flow pattern that is produced by EXAIR’s Super Air Amplifier. The Super Air Amplifier utilizes a patented shim design that maintains a critical position of the air gap and creates a laminar air flow pattern that will exit the outlet of the unit.

fan data2

In addition to providing laminar air flow more conducive for cooling and drying, the Super Air Amplifier provides much more air that can be directed at the target. A standard 2.36” x 2.36” DC operated fan provides anywhere from 12-27 CFM at the outlet, depending on the model. For comparison, a Model 120022 2” Super Air Amplifier will provide 341 SCFM at the outlet when operated at 80 psig. At just 6” away from the outlet, this value increases to 1,023 SCFM!! When compared to the fan outlet air flow, the Super Air Amplifier produces more than an 1,100% increase in air volume!

When replacing a fan with a Super Air Amplifier, the process time can be dramatically reduced. The increase in air volume significantly reduces the contact time that your part will need to be exposed to the air flow, allowing you to increase your line speed and decrease the overall production cost of the part. This is achieved due to the nature in which a Super Air Amplifier draws in air from the ambient environment. At amplification ratios as great as 25:1, the Super Air Amplifier is the best way to move a lot of air volume across the part with very little compressed air supplied to it. Check out the video below for a good representation of the air entrainment of a Super Air Amplifier.

In addition to providing laminar airflow and increasing the volume of air, the Super Air Amplifier is also infinitely adjustable through one of two ways. Each size Super Air Amplifier has a shim set that can be purchased. Swapping out the stock shim for a thinner shim will reduce the compressed air consumption, force, and flow. Installing a thicker shim will increase it. Additionally, the force and flow can also be adjusted by regulating the input supply pressure through the use of a pressure regulator. With sizes ranges from ¾” up to 8”, there’s a Super Air Amplifier for all applications. Give us a call today to see how you can optimize your process by replacing your fans with one or more Super Air Amplifiers.

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.

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.

Adjustable Air Amplifier

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.

Compressed Air – Diagnose a Car Problem or Simulate Ape Breath

At the end of this week and all through next week, I will be taking my family to the “most magical place on earth!”  Keep in mind, I have three daughters at the ages of 5 (almost 6 if you ask her), 3, and 1. (Not to mention my wife who has spent endless hours researching and scheduling our events for the week.) It’s not just my household that is going on this trip though, it is my entire family, parents, siblings, teenage nieces, and one nephew.   I honestly don’t remember the last family vacation we went on with all of us there so it is going to be an amazing experience no matter what.

Cin-Orl
Cincinnati to Orlando = 13 hours (not with kids)

The trip from Cincinnati, OH to Orlando, FL is approximately 13 hours, factor in the children and parents ages and I am going to go ahead and say we are looking at 24 hours of travel, at least.   Now I am being smart, we are breaking this trip up into two days. I envision something that will look like a military convoy going down I-75 when the 3 vehicles all get going, the painful truth is it will look more like the Clampets move to Hollywood.

In preparation for the trip I have been doing some routine maintenance on our family van and discovered what I believed to be a rather bad coolant leak.  Now, I didn’t see the leak but I noticed the lack of coolant in the system.   So I started to conduct a few tests and oddly enough, they involved compressed air.   First I filled the system and pulled a vacuum on the entire cooling system to draw out any air.   Once I pulled around 11″ of mercury, I went ahead and turned off my compressed air vacuum generator and tried to see if it would lose vacuum.  It didn’t, so I then hooked a hose to a container of coolant and slowly released the vacuum sucking the coolant down into the system and eliminating the risk of air bubbles.

Since I couldn’t see a loss in vacuum I decided I would test the system under pressure.  To do this I simply removed the radiator cap and attached a special tool which would pump air down into the radiator and put the entire system under pressure, much like it would be during normal operation.  Once I built the pressure up to 15 psig, the factory cap was rated for 16 psig,  I let it sit.  I scoured every single coolant line I could find and came up dry.  Couldn’t find a single drop of coolant escaping the system at all and it even held pressure for a solid hour. Coming up with no leak I decided to give it a test drive and low and behold, I have yet to find a leak.  My only theory at this point is during some warranty work a dealership must have disconnected a hose and forgot to fill it back up, or it is normal evaporation seeing as how I don’t remember the last time I topped off the coolant.

The entire time I was troubleshooting this system I found it interesting I was still using compressed air in some form, even on a liquid cooling system.  I then started to wonder if I am going to be able to see any EXAIR products while at that magical park in Orlando, hopefully something like the Roaring Banana Breath that is featured in our Super Air Amplifiers section of the catalog. Our amplifiers also get used to puff air at folks during other “4D” experiences throughout the world.

EXAIR Super Air Amplifiers help disperse banana scents into the air and into the face of patrons at a theme park ride.

Nonetheless, compressed air helped me determine that my family’s vehicle is not going to be spraying coolant on the roadway during this trip and I am glad for it.

How Much Force Does It Take?

In case you weren’t aware, the answer to “How much force does it take?” is always going to be, ALL OF IT.   At least that is what we generally think when trying to blow product off a conveyor belt or diverting parts into bin, etc. Speed and efficiency play a direct role in to what nozzle or blow off device you should use in order to get the job done and be able to repeat the process.

The question we are often asked by customers is, “How much force to I need to move this?”  That is a question that we cannot often answer without asking more questions.  The good part of this is, there is a formula to calculate just how much force you need to move an object.   A good video explaining friction is shown below.

In order to answer the question of how much force do I need, we really need to know all of the following:

Weight of the object
Distance from target
Is it on an incline or level
Distance needed to move
Then, the usually unknown variable, the coefficient of friction between the target and what it is sitting on.

Often times it is the thought process of, my target weighs 5 pounds, I need 5 pounds of force in order to move it from the center of this conveyor belt to the edge, this is not the case.   If you wanted to lift the object over a break between two conveyors then you would need slightly more than 5 pounds in order to ensure you are lifting the front edge of the unit high enough to meet the other conveyor.

Whether you know all of the variables or only a few, if you need to get an object moved and you want to try using compressed air to do so, give us a call and we will help you find the best engineered solution for your application.  Then, we’ll back all stock products with a 30 day guarantee if you don’t like how the system performs – but rest assured, we get it right almost every time.

Back At Ya!

This may not be big news as it happens almost every month.  EXAIR is continuing to grow our product line and this time it is something we have never done before.  This new EXAIR Engineered Solution doesn’t blow debris away, instead, it all comes back towards you.   Why would you want this you ask?  What does this new-fangled contraption look like?  Both of those questions will be answered below.

To answer the first question, why would you ever want debris to come back at you?  Well, this isn’t for just blowing any part or area out, this nozzle has been designed for a special purpose – to blow out pipes, tubes, extrusions, and even some blind holes or pockets.   This is ideal when working on a piping system that you may need to clean out and don’t want to push debris further into the system.   It is a quick and easy way to clean out chips from a saw cut operation for tubing or extrusion.  The nozzle could even be used to clean out cylinders or crank shaft openings on engine blocks.

So what is the name of this new nozzle and what does it look like?

What does it look like already!
What does it look like already!

 

The EXAIR Model 1006SS - Back Blow Nozzle
The EXAIR Model 1006SS – Back Blow Nozzle

This is it, the EXAIR model 1006SS Back Blow Nozzle.   The nozzle features a 1/4″ FNPT air inlet, a 3/4″ O.D. to fit into piping, extrusion, or holes, and two flats which allow for the use of a 5/8″ wrench to install the nozzle.   The nozzle is constructed of 316 Stainless Steel, utilizes  22 SCFM when operated at 80 psig, gives off 80 dBA and is designed for use with 7/8″ to 4″ I.D. pipe, tube, or holes.

The unit will also be available on our Safety Air Guns with Chip Shields to offer cleaning excellence and protection for the operators.  Like all of the stock EXAIR products, this is available with our 30 day guarantee.   So if you are not sure whether this nozzle will work on your application, give us a call, get one in, and put it through the paces.   If the Back Blow nozzle doesn’t meet your needs, simply let us know within 30 days from the date of purchase and we will take it back and provide you full credit.
