Don’t Forget the Hoses – Benefits for Compressed Air Applications

Published on by johnball2014Leave a comment

EXAIR offers different styles of hoses and tubes as accessories to our product lines.  They are built and designed to easily fit with our products as well as being sized correctly to not affect performance.  It simplifies the use, setup, and integration of EXAIR products in your facility.   You do not have to find the proper diameters, pressure ratings, and end fittings that will work and maximize the performance.  EXAIR has them in stock and ready to ship. In this article, I will go over the different types of hoses and tubes that EXAIR can offer.

Coiled Hose

Coiled Hoses: To get compressed air from the piping system to the Safety Air Guns, we offer a series of Coiled Hoses.  They are made of a durable abrasion-resistant nylon material that is 12 feet long (3.6 meters).  They have swivel fittings to allow for easy uncoiling, and a spring strain relief to keep the hose from kinking.  The coiled design makes it easy to reach around the work area and retract back to the substation.  This will help to keep the hose off the ground where potential dangers could occur.  We offer 3 different connection sizes of 1/8” NPT, ¼” NPT, and 3/8” NPT to attach right to the Safety Air Guns.  With the proper size, the Coiled Hoses can supply the required amount of compressed air with a minimal amount of pressure drop.

Compressed Air Hose

Compressed Air Hoses: If you need a compressed air line to reach from overhead or around equipment, the EXAIR Compressed Air Hoses would work with these applications.  They are made from a reinforced synthetic rubber in 3/8” I.D. and 1/2” I.D. diameters.  We can make specific lengths up to 50 feet (15m).  They are rated for 250 PSIG (17 bar) air pressure, and the hose material works well for long-lasting protection against ozone, weathering and temperatures up to 158oF (70oC).  They come with two male ends in ¼” NPT or ½” NPT.

Flexible and durable, EXAIR Stay Set Hoses come in lengths from 6″ to 36″.

Stay Set Hoses: The Stay Set Hose gives you that possibility of manually adjusting or re-adjusting Super Air Nozzles.  The hose has a “memory” function, and it will not creep or droop until you physically move it.  They work well to direct air flows in specific target areas.  They can be used with Super Air Nozzles, Safety Air Guns and Blow-off Kits.  The Stay Set Hoses come in lengths from 6” (15cm) to 36” (91cm), and they are offered with ¼” NPT male on both ends or with a 1/8” NPT female and a ¼” NPT male connections.  These hoses are rated for 250 PSIG (17 bar) and are made from reinforced synthetic rubber.  If positioning is required for accurate blowing or re-positioning for different applications, the Stay Set Hose would be a nice addition to your equipment.

Conveyance Hose – 3/8″ – 3″

Conveying Hoses: The hoses above are used with our Air Operated Conveyors or Line Vacs.  The Line Vacs are designed to move product from point A to point B.  If the Line Vac is the “vehicle”, the Conveyance Hose is the track.  The hoses are made of a durable PVC semi-flexible hose with 6 different diameters from ¾” I.D. to 3” I.D.  The conveyance hose can slip easily onto the non-threaded style of the EXAIR Line Vacs.  EXAIR can cut-to-length Conveying Hoses up to 50 feet (15m); in increments of 10 feet (3m).

Vacuum Hose

Vacuum Tubing: For our E-Vac product line, EXAIR offers vacuum hoses to connect the E-Vac vacuum generators to the suction cups.  They are made from polyurethane in ¼” O.D. and 3/8” O.D.  The vacuum hose is very flexible for moving product, and they can resist the vacuum pressures created by the E-Vac.  They slip into our Push-In Connectors to quickly attach vacuum cups to the E-Vac system.  EXAIR can sell both sizes up to 50 feet (15m) in increments of 10 feet (3m).

Hoses and tubes may seem like simple things, but EXAIR already did all the research in determining the best material and correct size for optimum performance.  You can leverage this information to save you time and money when using EXAIR products in your application.  If you need help in selecting the correct model, you can contact an Application Engineer.  We will be happy to help you.

The (Not So) Dreaded Warranty Claim Call

Published on by Russ BowmanLeave a comment

If you’ve ever worked in customer service or technical support, it’s almost a foregone conclusion that you’ve spoken with someone who isn’t getting what they wanted from your products and/or services. And no matter who you are, you’ve almost certainly spoken with someone you’ve bought something from, because you’re not getting what you wanted from it, right? And we can all (I hope) agree that there are MANY things we’d rather do than make…or receive…those calls.

I had the pleasure of assisting a customer yesterday who wasn’t getting what he wanted from an EXAIR product: in this case, it was one of our Stay Set Hoses. It seems that the bendable element inside had broken, meaning the Stay Set Hose was no longer “staying set.”  Since this unit had only been in service for about a month, I was anxious to know what would cause such a failure on a solid product with such a successful track record.  The caller was up front, early in the conversation, with his understanding that we can’t warranty against everything that a user might do to our products (the fact of the matter is, we do honor a 5 year “Built To Last” warranty against manufacturing defects,) and we shared a quick laugh because we both remembered this luggage commercial:

By this time, it was the best warranty claim conversation ever.

Flexible and durable, EXAIR Stay Set Hoses come in lengths from 6" to 36".
Flexible and durable, EXAIR Stay Set Hoses come in lengths from 6″ to 36″.

This particular Stay Set Hose was one of many in their plant, so we had a good discussion of some common best practices for their use:

*Keep bends as gradual as possible, especially if repositioning is frequent.

*Use two hands to bend the hose, as much as possible, to prevent/limit an excessive amount of leveraged force being applied to the connecting end of the bending element.

*When re-positioning is needed, do not grab onto the point of use device (Air Nozzle, Air Amplifier), but instead, use the spring relief as a grip to bend the blow off device into place.

*Keep in mind they’re PVC…temperature rating is 158°F. They’ll handle a fair amount of heat, but take advantage of their flexibility and bend them well away from any hot surfaces.

Like I said, this hose had only been in service for about a month, so we’re getting it back in the shop for failure analysis. Stay tuned for a future installment, where I’ll tell you how the rest of EXAIR’s warranty evaluation process works.
