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…

Custom Solutions For Conveying Dry Material

The ideal solution for conveying large volumes of material over long distances.

EXAIR’s Line Vac compressed air operated conveyors have no moving parts or motors to wear out, providing a maintenance free way to move dry material from one location to another. We offer several different types and sizes of Line Vacs like our Standard Line Vacs, available from 3/8″ up to 5″  or our Threaded Line Vacs, with NPT threaded connections up to 3″. The Heavy Duty Line Vac are constructed of Hardened Alloy for superior abrasion resistance, available in sizes from 3/4” to 3”, smooth and threaded connections or the Light Duty Line Vac commonly used for smaller volume, shorter distance processes, with sizes from 3/4″ to 6”. We even offer Sanitary Flange Line Vacs from 1-1/2″ up to 3″ for processes requiring frequent cleaning. All of these products are in stock, ready to ship from our factory here in Cincinnati, Ohio.

For over 34 years, EXAIR has been manufacturing Intelligent Compressed Air Products and we understand that there may be “special” cases where a stock product isn’t going to fit a specific need or requirement. What sets us apart from our competition is that we are able, with a little help from the customer, to engineer and manufacture custom made products, like the Line Vac Conveyors, to fit the specific demand of a unique application.

A few examples are shown below:

Flanged design, easy to install


This special 3/4″ Stainless Steel flanged Line Vac is being used to remove acidic vapors after a silicon wafer etching process. The flanged design allowed the user to direct mount to the machine, eliminating the need for other expensive modifications.

 

 

 

Chemical resistant construction for washdown areas

 

 

A customer was needing a special Line Vac for a chloride wash area due to the aggressive chemicals. We were able to make a custom 1-1/2″ Line Vac in PVDF construction for corrosion resistance and QF flanges for easy maintenance and cleaning.

 

 

 

Custom funnel design for small, granulated material like sugar or salt

 

This special funnel shaped Line Vac is being used in a a small packet filling operation. The unique design assured for a clog free process by keeping the granulated material moving through the tube.

 

 

 

 

 

Miniature size for confined workspaces

 

A company was needing a miniature version of a Line Vac to remove microscopic debris in an integrated circuit chip making process. The barb fittings allowed for easy installation into the small work place.

 

 

 

 

 

These are just a few examples of how we are able to meet the demands of a wide variety of extraordinary processes. Whether you are looking to move “common” materials like plastic pellets or maybe something “off the wall”, chances are we have the resources to provide an engineered solution to fit your need. Our application engineers are standing by, so give us a call and let us put our expertise to work for you!

When Is A Half Inch Not A Half Inch? When It’s Half Inch Pipe, Of Course!

People have been using pipe to transport fluids for thousands of years. Archeologists have discovered evidence that the Chinese were using pipes made of reeds for irrigation as early as 2,000 B.C. Lead pipe began to supplement, and eventually replace, the Roman aqueducts in the first century A.D. In the early 1800’s, someone got the idea to use gas burning lamps to light city streets, and, over the next few years, men like James Russell and Cornelius Whitehouse came up with better and better methods of mass producing metal tubing and pipes.

Over the course of the 19th Century and the Industrial Revolution, iron pipe came to be manufactured in standard sizes, which were called out by the inside diameter of the pipe. ¼” pipe had a ¼” ID, ½” pipe had a ½” ID, ¾” pipe had a ¾” ID, etc. Iron pipe could be found in any facility that needed to move a gas or a liquid: factories, power generating stations, chemical plants…you name it.

As engineers and metallurgists came up with new ways to produce pipe, technological advances led to the ability to decrease the wall thickness and still maintain high structural integrity. This was a HUGE improvement: not only could piping manufacturers make more pipe with less material, bringing down the cost, it was also lighter in weight, making it easier to transport, handle, and install. Because of the massive amount of existing piping already in place, it made sense to keep the outside diameter the same, so that all the fittings would match when these facilities went to replace worn out or damaged pipe. So, the inside diameter was increased. That’s why, today, ¼” pipe has a 0.36” ID, ½” pipe has a 0.62” ID, ¾” pipe has a 0.82” ID, etc. Lower cost, lighter weight, more flow capacity…it’s all good, right?

Well, yes, but sometimes, it can lead to confusion, especially when we’re talking about properly sized compressed air lines. See, we know how much compressed air will flow through certain sized pipes of specific lengths. The Installation & Operation Instructions for all of our products contain recommended infeed pipe sizes to ensure sufficient air flow. Keep in mind, these are Schedule 40 pipe sizes, and should not be confused with hose or tubing sizes, which usually report the outside diameter but could also report the inside diameter, depending on the source.

Consider this example: you want to install an 6” Super Air Knife in a location 10 feet from the compressed air header. Following the “Infeed Pipe Size Length of Run” column (10’) down, we see that this will require a ¼” SCH40 pipe, which has an ID of 0.36”. If you want to use hose or tubing to supply it, that’s fine – it’ll have to have a 3/8” ID, though, or you’re going to risk “starving” the Air Knife for air. If you choose a 3/8″ tube remember that dimension is usually referring to the outside diameter of the tube and automatically means your inside diameter is smaller than we would recommend.
