EXAIR's Threaded Line Vac Family

What’s So Great About Threaded Line Vac Pneumatic Conveyors?

Published on by Russ BowmanLeave a comment

Conveyor systems come in many shapes, sizes, and configurations. They can be run at different speeds, and are made of various materials, depending what they’re carrying, and why they’re carrying it. And sometimes, they’re hilarious:

If you’re looking to move solids, in bulk, through pipe, there’s not a simpler way to do it than with an EXAIR Threaded Line Vac.  Like our ‘standard’ Line Vacs, they use compressed air to generate a powerful vacuum flow to get air behind the pieces and carry them along:

Instant conveyor – just add compressed air.

But, while the ‘standard’ Line Vacs are made for use with Conveyance Hose, the Threaded Line Vacs have male NPT threads so you can pipe them in line.  We have a range of options, depending on the nature of your applications:

  • Sizes: 3/8 NPT to 3 NPT.
  • Materials: aluminum, 303SS, 316SS, and hardened alloy.
  • Performance: aluminum, 303SS and 316SS Threaded Line Vacs are made for standard duty; the hardened alloy Heavy Duty Threaded Line Vacs offer higher vacuum performance as well as superior abrasion resistance.
  • Environment: the materials of construction listed above may be important because of the nature of the product being conveyed, but they also have different temperature ratings.  Our Stainless Steel Line Vacs also come in a High Temperature design, in case the material – or the environment – is particularly hot:
    • Aluminum: 275°F (135°C)
    • Heavy Duty Hardened Alloy: 400°F (204°C)
    • 303 or 316SS: 400°F (204°C)
    • High Temp 303 or 316SS: 900°F (482°C)

If you’ve got a conveyor application you’d like to discuss, give me a call.

Threaded Line Vacs: Low Cost Conveyor Uses Ordinary Pipe!

Published on by Leave a comment

EXAIR’s Threaded Line Vac air operated conveyor takes an ordinary pipe and converts it into a powerful conveying system.  A fast, low cost way to convey items such as pellets, scrap trim, bulk solids, chips, paper, small parts, sawdust, granules, and so much more. The Threaded Line Vac attached easily to plumbing pipe couplers, like PVC or iron, making it easy to build a complete system with parts readily available from your local supply house or hardware store.

The Threaded Line Vac are ideally suited for conveying large volumes of materials over long distances.  Like the standard, smooth bore ended Line Vacs, the unit works by ejecting a small amount of compressed air to produce a vacuum suction on the inlet side and a high output flow from the outlet side.  By using a pressure regulator to control the compressed air supply pressure, the rate of conveyance can be controlled to match the application needs, while minimizing the compressed air usage.

Models are available from 3/8 NPT to 3 NPT with materials of construction of aluminum and types 313 and 316 stainless steels (excellent corrosion resistance.)  High temperature versions of the stainless steel Threaded Line Vacs are available as well, for temperatures up to 900°F.

For those processes requiring the highest rates of conveyance over the longest distances and/or the most abrasive of materials, the Heavy Duty Threaded Line Vac is the right choice.  Designed with the most rugged industrial processes and applications in mind, the special hardened alloy construction helps prevent premature wear that could occur with standard aluminum or stainless steel models, under the harshest of conditions.  The performance has been boosted, to be able to convey more material, over longer distances and higher vertical rises.

To select the right model, information regarding these criteria is helpful-

  • Size of parts and bulk density of material being conveyed
  • What size hose, tube, or pipe is desired
  • Target conveyance rate
  • Distance of conveyance, both horizontal and vertical legs
  • Preferred material of construction

For another look, please see the video available that provides more details about the Line Vac family.
