EXAIR Products “Built to Last”

Published on by EricKuhnash@EXAIR.comLeave a comment

When I hear “Built to Last” ads come to mind such as Ford Trucks and Craftsman tools. Advertising promoting product integrity will always get my attention. Although I have not owned a Ford truck, I have many friends that have and swear by them, so I’m thinking my next truck might be a Ford. I have owned a lot of Craftsman tools and put them through rigorous use and I never had to use the “Lifetime Warranty”. They were designed and built to last and this is how EXAIR designs and manufactures their Intelligent Compressed Air Tooling.

EXAIR Design and Engineering team designs our items with performance and repeat manufacture ability in mind. EXAIR products have no moving parts so very little maintenance is required. As long as a source of clean dry compressed air is supplied to the product and following our recommended Installation instructions not much can go wrong,

EXAIR has a “5 Year Built to Last” Warranty against defects in workmanship and materials on all compressed air products. This warranty applies under conditions of normal use, but does not apply to defects that result from intentional damage, negligence, unreasonable use, wear or exposure. An example of a non warranty situation would be using an abrasive material such as sand with our Aluminum Line Vacs. The abrasive nature of the sand will wear the aluminum Line Vac out well before the 5 years. Our application engineers will discuss your application and recommend products that fit your project and our 5 Year Built to Last Warranty.

EXAIR also has a 30-Day Guarantee that allows you to make a purchase and run trials to see the effectiveness of our product and how they meet your expectations. If the item provides desired results then great we are both happy but if you do not see the desired results then you have 30 Days from purchase to return the product. An Application Engineer can discuss your findings and issue a “Return Authorization” if needed. You will receive a full credit without any restocking fees.

EXAIR has confidence in our products to last and perform standing behind our products. Our confidence is why we offer both 5 Year Built to Last Warranty and the 30-Day Unconditional Guarantee. If you have any questions as to what EXAIR product will provide the best result for your application, please contact one of our qualified Application Engineers, so we can review this with you and make the best recommendation for your project(s).

EXAIR has Intelligent Compressed Air® Tooling

Published on by EricKuhnash@EXAIR.comLeave a comment

I used to work for a plastic injection molding facility that also had several different types of secondary added value processes. We used compressed air in our paint rooms, assembly areas, molding room and other various processes. I don’t recall what our compressed air usage was as we had 7 total manufacturing facilities in 5 different states. I tracked our electric bills, phone bills, water bills and all of our vending billing but, I never took the time to realize the importance and cost of compressed air.

I was successful in cost reduction activity in all those ares and so proud of the accomplishments but not once did I take the time to realize what I could save with our compressed air systems and the tooling we used with compressed air. The illustration below shows what can be saved when looking at just one air nozzle:

Compressed Air Savings

This is just one air nozzle. We used about 100 Air Nozzles, 20 paint nozzles, 50 Line Vacs and other various compressed air products. If I was able to calculate savings for all the products we used and focused on fixing air leaks in the system I would have been a real hero. Well guess what? EXAIR can help you calculate and determine the best products to help you generate these savings. We can even help you calculate your savings.

The other benefits included with EXAIR Intelligent Compressed Air® products will be the noticeable noise reduction and compliance with OSHA Standards 29 CFR-1910.95(a) Maximum Allowable Noise Exposure and 29 CFR-1910.242(b) Harmful Dead End Pressure. EXAIR meets or exceeds these OSHA Standards providing you with a peace of mind for conformance.

EXAIR has a great catalog showing our products, capabilities and performance information. Our website www.EXAIR.com offers catalog information, prices, performance, drawings, videos, blogs, air savings calculator and much more information. If you are unable to find what you need you can conveniently call one of our Application Engineers for assistance.

How To Make Your Own Air Wipe – And Why You Shouldn’t

Published on by Russ BowmanLeave a comment

If you have the right tools and a basic knowledge of metalworking, it’s not all that difficult to make a device to blow off wire, hose, or tubing that can be passed through. You just drill a hole through the center of a piece of bar stock (for the material to pass through), drill a couple of angled holes from opposite outside surfaces to the center hole you just drilled (for the air to blow through) and tap the start of those holes to thread your air supply line fittings into. You can even get fancy and cut it in half axially & hinge one side, so you don’t have to thread your material through it every time.

Will it work? Probably marginally. Will it be loud & inefficient? Definitely. Is there a better solution? Yes…and EXAIR has a shelf full of them.

What I described in my opening paragraph is a typical ‘block type’ air wipe device. If you don’t have the aforementioned right tools or metalworking acumen, you can buy them from a number of sources. They’re usually pretty cheap, and with a little engineering, their marginal performance can be improved, but there’s no getting around the noise level and inefficient compressed air use. The added air consumption, in fact, will steal your savings on the low purchase price in a hurry.

Come October, EXAIR will have been making quiet, efficient, and safe compressed air products for 40 years. Among these engineered products is our line of Air Wipes.

On the left is one of the ‘block style’ air wipe devices I described above. On the right is an EXAIR Super Air Wipe.

Engineered products like our Air Wipes offer a host of benefits. Consider:

  • Effectiveness. The block styles, by design, blow air through open-ended holes in the passage. Not only is this (again, by design) unevenly distributed around the perimeter of the material passing through, it’s also turbulent in nature…the force of the air flow really just impinges, or beats, on the surface. The EXAIR Air Wipe, by comparison, generates an even, steady 360° converging air flow that, by design, is laminar in nature…this makes for a stripping/sweeping action for superior cleaning/drying/blowoff of the material passing through.
  • Low sound level. The air flow coming out of the internal holes in the block style device can be ear-piercingly loud. An open ended discharge like that converts the potential energy of the compressed air to kinetic energy in the form of force, and noise. The EXAIR Air Wipe uses a relatively lower flow of compressed air to entrain surrounding air which, when forced to converge on the material via the Air Wipe’s Coanda profile, results in a much lower sound level. The Model 2399 3/8″ Super Air Wipe shown above, for example, generates a sound level of only 82dBA with an air supply pressure of 80psig.
  • Efficiency. Even if the holes in the block style device are as small as 1/4″ in diameter, they can still be flowing as much as 33 SCFM, each, with a supply pressure of 80psig. The 3/8″ Super Air Wipe, by comparison, uses only 11.1 SCFM @80psig.
  • Ease of installation. This is where the block style comes closest to competing, but the EXAIR Air Wipe still wins out. While both of the products in the above photos are a split design (meaning you don’t have to thread the material through), the EXAIR Air Wipes only require one air supply line (due to the connecting hose assembly that evenly distributes air to both halves), and the smaller ones (like the 3/8″ and 1/2″ models) can be supported by the air supply line itself, if you use pipe.

EXAIR makes Air Wipes as small as 3/8″, and as large as 11″. Standard Air Wipes feature aluminum construction, polyester shims, and a PVC/rubber/brass connector hose. Super Air Wipes have stainless steel shims & hardware, a braided stainless steel connector hose, and come in aluminum or stainless steel construction. And they’re all on the shelf, available for immediate shipment.

Air Wipe Kits come with the Air Wipe itself, a Shim Set, an Automatic Drain Filter Separator, and a Pressure Regulator w/Gauge.

EXAIR Air Wipes are just one product line of our Intelligent Compressed Air Products. If you have a blowoff, cooling, cleaning, or drying application you’d like to discuss, give me a call.

Are you looking for a reliable heavy-duty vacuum system? Are you tired of your electric motors failing? EXAIR has a pneumatic Heavy Duty Dry Vac that is engineered with the power to vacuum heavy materials, The Heavy Duty Dry Vac is constructed from a hardened alloy that resists abrasion from the harshest of debris, like garnet, glass, tumbling media and steel shot. This system has no moving parts which means no motors or bearings that can fail on you.

The Heavy Duty Dry Vac requires only 68 SCFM at 80 psig of compressed air to operate. Using a hardened alloy construction for the vacuum generator gives the system an increased resistance to abrasive material including sand and blasting material. Depending on your application and the volume of material you need to vacuum we provide 3 different sizes, 30-gal, 55-gal, and 110-gal.  

Our Heavy Duty Dry Vac is the perfect solution for cleaning dry media such as abrasive media, sand blasting, absorbents and gravel from your shop floors and work surfaces. The possibility of electric shock you experience with electric motors is virtually eliminated as the source of power is compressed air. The use of an anti-static hose also prevents shocks when vacuuming dry materials.

EXAIR Heavy Duty Dry Vac Family

EXAIR‘s Heavy Duty Dry Vacs come in 30, 55 and 110 gallon options with several accessories available to help your cleanup and specific needs. These are stock items and can generally be shipped the same day with orders received before 2:00 PM EST. If you have questions regarding our Heady Duty Dry Vac or any of our Industrial Housekeeping Products please give us a call.
