The Case For The EXAIR Super Air Wipe

If you’ve ever used an air gun to blow something off, you’re familiar with the cleaning ability of compressed air.  If you can get the whole object blown off from where you’re standing, there really is no substitute…but what if you need to get to the other side…or sides?

Even if your product is not on fire, you probably wouldn’t want to “limbo” under it with an air gun…

This is where the EXAIR Super Air Wipe comes in…they allow you to blow a continuous, uniform 360° air stream, all around your product.  Consider their benefits:

*Sizes: the Super Air Wipe’s compact ring design means it won’t take up a lot of room; you just need a few inches, in any direction, to install one.  We stock them in eleven sizes, from 11″, all the way down to our brand-new 3/8″ diameter.

*Durability:  All EXAIR Super Air Wipes are assembled with stainless steel shims and hardware.  Models up to 4″ come with a rugged, stainless steel wire braided hose, connecting the two halves for compressed air supply.

The aluminum Super Air Wipe is available in 11 sizes; the stainless steel Super Air Wipe comes in 5 sizes…all from stock.

*Ease of installation:  Smaller sizes can be supported by the compressed air supply line, if a pipe is used and threaded into the connector hose’s 1/4 NPT port.  Larger sizes can likewise be adequately supported with pipe to both halves. All models have a bolt circle of 1/4″-20 tapped holes for more permanent and rigid mounting.  The split ring design is another key feature:

Simply open the two halves, and clamp them around your product…no threading!

*Corrosion resistance: Depending on the environment in which the Super Air Wipe will be installed, we offer them with aluminum (3/8″ – 11″ sizes) or stainless steel (3/8″ – 4″ sizes) bodies.

*Temperature rating: Aluminum Super Air Wipes are good to 400°F (204°C) and stainless steel models are good to 800°F (427°C.)

*Range of operation: We install a 0.002″ thick shim in all stock Super Air Wipes; this is suitable for a wide range of typical industrial/commercial blow off applications…a Pressure Regulator can then be used to “dial in” the air flow precisely to meet specific needs.  If a job calls for higher force & flow, additional 0.002″ shims can be installed.  Shim Sets come with the Super Air Wipe Kits, or individual shims can be ordered separately.

*Performance: Before the Super Air Wipe, a ring of nozzles was commonly used.  In fact, they still are, but we’re trying to fix that, at every opportunity we come across.  Problem with those is, it’s hard to get an even air flow all around, which leads to inconsistent blow off.  They can also be loud & inefficient, as we’ve found in numerous Efficiency Lab tests and Case Studies, like this one…

These wasteful and loud modular plastic tube blow offs…
…were replaced with EXAIR Super Air Wipes. 24 such replacements netted the customer an annual compressed air cost savings of over $13,000.00.

…and this one…

Implementing a Super Air Wipe salvaged a $30,000 job for this customer. Click on the picture to read all about it in our Case Study Library (registration required.)

Adjustable Air Amplifier Keeps Sensor Cool

Our distributor in China has a customer who visited the United States, while their customer was in the US they saw an EXAIR product installed and wanted to replicate the setup in China. He saw the EXAIR label and reached out to our distributor for help in identifying the part. Taking a quick measurement of the inlet side of the Adjustable Air Amplifier led us to discern it was a Model 6041 1-1/4” Adjustable Air Amplifier.

EXAIR Model 6041

The product was installed on a baghouse monitoring system. The sensor is used to detect minor leaks within the dust collection system before the leaks create a major problem. The environment in which the sensor was installed results in temperatures that are just above the normal operating temperatures during warmer months and can result in erroneous readings. When this occurs, production is shutdown to prevent a failure of the dust collection system while the filters can be inspected. By installing the Adjustable Air Amplifier to provide a large volume of air and a low level of compressed air consumption, the temperature is able to be maintained within typical operating range for the sensor. This alleviates the need for unnecessary shutdowns (or unnecessary filter replacement), while ensuring that the working environment remains dust-free.

EXAIR’s Adjustable Air Amplifiers are available in both Stainless Steel and Aluminum from sizes ranging from ¾”-4” on the air outlet. The outlet can be ducted as seen in this application, or it can be used as-is. The air gap of the Adjustable Air Amplifier is infinitely adjustable, allowing you to regulate both the air consumption and outlet flow from a “breeze” to a “blast”. In addition to the standard Adjustable Air Amplifiers, we also have a Model 121021 High Temperature Air Amplifier available that is capable of withstanding temperatures as high as 700°F.

Air Amplifiers can be used in a variety of different applications. Not only can they be used in applications requiring cooling, but the air entrainment properties of the amplifier can be used to exhaust smoke as discussed in this application at a foundry. An Adjustable Amplifier can also be used for drying or cleaning parts as well as for conveying light materials.

Regardless of the application, EXAIR has a suitably sized Air Amplifier to fit your needs. If you need an efficient and reliable way to vent, cool, clean, or dry parts give us a call. An Application Engineer would be happy to take a look at your application and provide the best recommendation.

When Efficiency And Practicality Collide

Even if you’re a casual reader of our blogs, you already know that EXAIR Application Engineers LOVE to preach efficiency in the use of compressed air…it’s our “bread and butter;” the very nature of our business. This year, we’re celebrating thirty-five years of leading the way in the development of efficient, safe, and quiet compressed air products. Our track record of success as a solutions provider across a diverse range of industrial and commercial applications is well documented in our blogs, as well as Knowledge Base and Case Study Libraries.  We devote considerable resources (engineering, research & development, product testing, etc.) to making certain that EXAIR Intelligent Compressed Air Products cost less to operate, and perform better, than whatever you’re using right now.

Strange as it may seem, though, sometimes our products are EXTREMELY popular in cases where they INCREASE a facility’s consumption of compressed air…by replacing something that DOESN’T use compressed air at all:

*I’ve written before about how our Large Maximum Cold Temperature Vortex Tubes have replaced liquid nitrogen rigs in freeze sealing operations.  Now, a Vortex Tube directs a portion of its air supply to (usually) unusable hot exhaust, in order to generate the usable flow of cold air.  When compared to the costs of liquid nitrogen and the resources involved to get it where it needs to be, though, the cost of the compressed air needed to operate the Vortex Tube is indeed the practical solution.

A 1/4 ton of refrigeration from a product that fits in the palm of your hand, and all you need is a supply or compressed air!

*Line Vacs are probably THE prime example of the value of using compressed air where it wasn’t used before…replacing a “bucket and ladder” operation:

Straight from our Catalog, a perfect example of using valuable compressed air to save even more valuable resources.

*Then there are the situations that just come down to time.  In large spaces, our Super Blast Safety Air Guns can be used to “sweep” the floor in a fraction of the time it takes an operator with a push broom.

Super Blast Safety Air Gun makes short work of large area cleanup.

To make a long story just a little bit longer…if you’re using compressed air, you can use it better with EXAIR’s engineered compressed air products.  And there are plenty of practical applications where you’re not using compressed air right now too.  If you’d like to find out more about either one, give me a call.

How Versatile Are EXAIR Compressed Air Products?

I wish I could quantify that, but we keep finding more and more applications for them:

Vortex Tubes are used all the time for cooling applications, down to MINUS 40 degrees (Fahrenheit OR Celsius…that’s the point where they’re both the same; no math required.) They also produce a HOT air flow, which we usually call “exhaust,” but some users actually use IT for heating, and call the COLD flow the “exhaust.”

The EXAIR Vortex Tube. Cold air from one end; hot air from the other. Fully adjustable. You can use either...it's fine with us; whatever you need.

Our E-Vac Vacuum Generators are popular for “pick-and-place” jobs…hook one up to a Vacuum Cup and you can move parts around all day long. One time, though, I helped a

customer who needed to “pick-and-place” individual small pieces of woven fabric, a lot like a coffee filter. Even our smallest E-Vac, supplied from a Pressure Regulator cranked all the way down, was too much…it would still pick up most of the stack. We found they could use a Model 120020 3/4″ Super Air Amplifier just fine…the Pressure Regulator was still cranked all the way down, and it picked them up one at a time.

No matter what you need to pick-and-place, we've got you covered.

Our Super Air Knives are perfect for blow off, drying, and cooling applications…whether you’re trying to rid your product of dirt/debris, water, or heat, a laminar curtain of adjustable air flow is a “textbook” solution. But I recently had the pleasure of helping a customer who needed to KEEP SOMETHING IN PLACE and called to ask about an Air Knife. They had small cups running single-file down a conveyor belt, with an overhead brush roller pushing down on them at one point so they could be treated on one side. Without something holding them in place, the tooling would simply push them off the side of the conveyor. It required frequent adjustment because they run different sized cups…and they almost always lost some cups when they switched to a different size, while “dialing in” the brush tension. By installing a Model 110036 36″ Aluminum Super Air Knife in place of the brush, they can hold any size cup in place with the downward air flow “curtain.” No more lost product when they don’t get the brush adjustment just right!

Continuous, even, fully adjustable curtain of air...EXAIR Super Air Knives come in lengths from 3 inches to 9 feet.

Cabinet Cooler Systems – Around The Clock (And Calendar) Heat Protection

So it was 19°F (-7°C) when I walked outside this morning. The layer of ice on my windshield was thin, but particularly stubborn, and I muttered under my breath. I have no business complaining about the cold…see, I moved to Ohio (on purpose) from Florida, in 1991. In November, to be exact. I still remember where I surrendered my “complain-about-the-cold” card:

If you’re headed north on I95, the next sign you’ll see is in Georgia. And if you’re not careful, you can end up “Up North.”

Why am I writing a blog about solutions to heat problems when, even though I do have a really nice pair of gloves, my fingers still aren’t even really thawed from ice removal duty this morning? Well, I’ve got three reasons:

1. Outside temperature doesn’t necessarily have any bearing at all on the temperature inside. Sure; there’s a reason we call July and August “Cabinet Cooler Season” – summer heat will do a number on sensitive electronic & control panels in spaces with no climate controls, but the problem goes away as winter approaches. In fact, there’s even such as thing as a cabinet HEATER, if the equipment in question is exposed to the elements.   Sometimes, though, heat is an issue year ’round…think blast furnaces, boiler rooms, foundries, chemical plants.  If your process generates heat, it’ll affect a control panel in the dead of winter just the same as on the dog days of summer.  We can quickly and easily specify the right Cabinet Cooler System for you with just a few key pieces of data…here’s a link to our Cabinet Cooler Sizing Guide if you want to find out.

2. It’s not winter all over the world.  Here in the Midwest United States, I full well realize we’re just gearing up for windshield scraping, snow shoveling, slipping-on-the-ice (some people call it skating and do it intentionally) season.  But right now, our friends in the Southern Hemisphere are getting ready for heat waves, sunscreen, and (hopefully) air conditioning.  So, in essence, they’re moving towards what we call “Cabinet Cooler Season.”

3. Our Cabinet Cooler Systems are so great, the 316SS Cabinet Cooler Systems with Electronic Temperature Control are actually up for Plant Engineering’s Product of the Year Award.  Because of their 316SS construction, they’re optimally suited for installation in harsh or demanding locations.  The Electronic Temperature Control offers continuous indication of internal temperature, and the ability to change the thermostat setpoint with the push of a button.  If you’re a current user, and you agree that they’re great, we’d appreciate your vote.  If not, I’m reluctant to encourage you to vote for it, but I suppose I can’t stop you from taking my word for it…

If you’d like to talk about protecting sensitive electronics from the heat, or from the environment, or both, I’d love to hear from you…give me a call.

EXAIR Provides Cooling Solutions – Even During Winter Months

An electrical enclosure in need of a reliable cooling solution.

On first glance, the enclosure shown above looks to be fairly large for use with an EXAIR Cabinet Cooler.  Our individual Cabinet Coolers have a maximum cooling capacity of 2,800 BTU/hr. (~820W), but we do provide dual Cabinet Cooler systems with capacities up to 5,600 BTU/hr. (~1642W).  So, although there are heat loads which are too large for use with an EXAIR Cabinet Cooler, we always perform heat load calculations for any potential application because until you run the numbers, you don’t really know.

Arrows identifying existing A/C unit

In this case, however, the customer already knew the required cooling capacity (~3,000 BTU/hr. or 880W) thanks to an existing refrigerant based system already installed (see arrows above).  This existing system was doing a great job of keeping the enclosure cool when it was working properly, but it was also prone to maintenance and breakdowns.  The facility maintenance technicians had replaced filters as required on their preventative maintenance programs, but the A/C unit still required replacement multiple times.  This would lead the maintenance team to open all the doors of the enclosure in an effort to remove heat, but this allowed dust and dirt to enter the cabinet and compromise the electronics inside.

Eventually, the maintenance, required repair, and exposure of sensitive electronics led this customer to search for an alternative solution, and they found the EXAIR Cabinet Cooler.  Once we determined the required cooling capacity and a suitable unit (model 4750 NEMA 4 Dual Cabinet Cooler System with 3,400 BTU/hr. (~1,000W) of cooling power), the discussion turned to installation and maintenance and we had a conversation something like this:

Customer: How much time do we need to hook up the Cabinet Cooler?

EXAIR: About five minutes.

Customer: That’s it!?

EXAIR:  That’s it!  I’ll send you a video of the installation process.

Customer:  Ok, what about PM (preventative maintenance)?

EXAIR:  There isn’t any.  Just feed it with clean, filtered compressed air and it will run for years.

Customer:  Ok, how do we turn it on and off?

EXAIR:  Well, you don’t have to.  You just install the thermostat and the system does the rest.  It’ll maintain whatever temperature setpoint you chose and comes preset to 95°F (35°C).

Customer:  What is the lead time?

EXAIR:  They’re in stock and ship same day.

After working through the application and questions from the customer, we were able to provide a sustainable, readily available solution that was a marked improvement from the maintenance prone refrigerant based system.  Our Cabinet Cooler allows for easy installation, no maintenance, and years of trouble-free operation.  If you have an overheating enclosure contact an EXAIR Application Engineer.  We’ll be happy to help you find a suitable solution.
