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.

Heavy Duty Line Vac is a Simple Solution When Mechanical Conveyors Fail


Line Vacs can convey many things.
Line Vacs can convey many things.


A manufacturing plant had a machine that would process 6mm ceramic beads into small medical components.  They used a screw type conveyor to move the ceramic beads from a large container into a hopper above the machine.  In this situation, the customer called EXAIR prior to determining which mechanical component failed.  They contacted the conveyor manufacturer for assistance.  Because of the complexity of the conveying system, it would take time to evaluate.  They had to determine if it was the motor, the gear box, the shaft, or electrical system.  Depending on which item that failed, there was a good chance that it would not be in stock.  With this length of downtime, it would cost the company much money and delays in shipments. The operation had to be shut down until they could find a way to keep the hopper filled with ceramic beads.  Being that they were under the gun, they contacted EXAIR to see if we could help.

In discussing their layout, the hopper was 10 feet away from the supply container, and the opening of the hopper was 10 feet above the floor.  These lengths were well within the limits of the EXAIR Air Operated Conveyors.  I suggested the model 152200 Heavy Duty Line Vac Kit.  This unit has the highest conveyance rate, and it can move items in the range of plastic pellets to steel shot.  It does not have any moving parts, so it makes it very simple, reliable, and long lasting.  The Heavy Duty Line Vac is made of a hardened steel that makes it very resistant to abrasion.  The next question he asked was if we had it in stock.   We did!!!  EXAIR stocks every cataloged model number for same day shipping with orders placed before 3 p.m. EST.  We were able to ship the Heavy Duty Line Vac that same day to get his operation back up and running.  He did mention to me afterwards that he wished he had at least one Heavy Duty Line Vac on his shelf as a backup system.  It could have saved his company an entire day of downtime.

If your company relies on mechanical conveying systems to move product, you may want to have an EXAIR Air Operated Conveyor on hand just in case of an emergency.  When things go wrong, you do not want to be down any longer than needed.  If you need help in sizing the correct Line Vac for your application, you can contact an Application Engineers at EXAIR.
