Why Is Ambient Air Entrainment Needed For Pneumatic Conveyance?

When attempting to convey material pneumatically it can sometimes not work as one may hope. This could be due to the lack of ambient air entrainment to generate the vacuum flow which lifts the material away and moves the material. The video above gives a brief example of this.

If you would like to discuss pneumatic conveying products or processes, please contact us. EXAIR’s Line Vac air operated conveyors are a great solution for manual “bucket and ladder” applications, hopper loading, scrap conveyance, media recovery and more!

EXAIR Line Vac Replaces Yet Another Injury-Prone Bucket & Ladder Operation

I recently had the pleasure of talking with a caller from a consulting firm that specializes in improved ergonomics.  They work with clients on everything from preventing carpal tunnel syndrome through the use of things like gel-filled mouse pads for office personnel, to preventing injuries in the workplace due to repetitive strain, heavy lifting, and other physically demanding tasks.  They called about an operation where workers used buckets to move 150 pounds of dense pellets from a large container into a smaller vessel for weight load testing.  After the test, they move the pellets back into the container, where they stay until the next test is to be run.  Then they do it again.

This, of course, was a great fit for a 2″ Heavy Duty Line Vac and a 10ft length of Conveyance Hose. They simply move the suction & discharge hoses from, and to, the storage container & test vessel.  Risk of injury is greatly reduced, as the whole Line Vac conveyance system is less than half the weight of one bucket of the material.

Line Vac + Hose + Compressed air supply = complete conveyance system solution.

This is just the latest success story in the long history of EXAIR Air Operated Conveyors.  They’re on the shelf in a range of sizes and materials of construction to meet most any need.  If you don’t see what you’re looking for, though, call me and we can discuss your needs.

EXAIR Heavy Duty Threaded Line Vac

EXAIR Threaded Line Vacs In Action!

EXAIR’s Heavy Duty Threaded Line Vac air operated conveyors can take ordinary threaded pipe and convert it into a powerful conveying system for pellets, scrap trim, bulk solids, chips, paper, small parts, sawdust, granules, and many other bulk materials. The Heavy Duty Threaded Line Vac attaches easily to plumbing pipe couplers, making it easy to build a complete system with parts that are readily available from your local home supply or hardware store.

They are available in 7 different sizes ranging from 3/8 NPT to 3 NPT and are made from a proprietary hardened alloy for superior abrasion resistance and performance. Heavy Duty Threaded Line Vac Air Conveyors are ideally suited for conveying large volumes of materials over long distances.  They eject a small amount of compressed air to produce a vacuum on the intake side and a high output flow from the outlet side.   Using a regulator to control the compressed air supply pressure, the rate of conveyance can be controlled to match what the application requires all while minimizing your compressed air usage!

The Heavy Duty Threaded Line Vac Kit includes a pressure regulator, filter separator to keep the air clean, modular coupler clamp (connects air regulator to filter separator, not shown below) and the mounting bracket for ease of installation.

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.
