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.

Line Vac – Air Operated Conveyors

Published on by Leave a comment

Convey parts, materials, and waste – with no moving parts!

The Line Vac is a fast, low cost way to convey pellets, scrap trim, textiles, bulk solids, food products, chips, and much more.  Simply connect to a standard hose, tube, or pipe and a powerful in-line conveyor is created.

Available in (4) materials – aluminum, 303 and 316 stainless steels, and a special hardened alloy, and (3) end connection types – NPT threaded, smooth bore, and the new sanitary flanged. Sizes range from 3/8″ up to a 6″. It is certain that an available Line Vac option will meet your process criteria.

For lighter materials and short conveyance distances, the Light Duty model is ideal, and for the most abrasive and heaviest materials over longer distances, the Heavy Duty style is available.

The Line Vacs offer many safety benefits, including eliminating the dangers of lifting heavy sacks and climbing ladders to fill hoppers, and with the 316 stainless steel sanitary flanged Line Vacs, food materials are kept enclosed and and separated and provides ease of cleaning.

The Line Vac works by having a small amount of compressed air injected through directed nozzles to produce a vacuum on one end and high output air flow on the other, with instantaneous response.  By using a pressure regulator, available as part of a kit or separately, the flow of the material transfer can be easily controlled. No moving parts or electricity assures maintenance free operation!

Conveyance rates are determined by the material bulk density, typical particle size, total distance of conveyance, including vertical rise, and the targeted transfer rate.  An EXAIR Application Engineer can assist you, and with the above information, recommend the right size and type of Line Vac to meet the desired results.

All catalog models are in stock and we ship same day with an order received by 3 pm EDT in the US and 2 pm EDT for orders shipping to Canada.

Our team of engineers can design a special Line Vac to meet many applications special requirements, from special materials such as PVC and PVDF to special end connections such as pipe flanges and barbed hose connections.  Let us know the special requirements of your process and we’ll design a solution.

Heavy Duty Line Vac Saves Backs and Shoulders!

Published on by Leave a comment

Recently, I worked with a customer that was looking for a way to make a difficult job easier, reducing stress and strain on the body and preventing injury.  The customer was in the Environmental Services & Hazardous Waste Management area and regularly was called out to service acid neutralization tanks. These are commonly found in hospitals, laboratories, and schools, to neutralize lab wastewater before it is discharged to the sanitary sewer.  The systems typically utilize limestone chips to aid the in process.

Periodic maintenance includes the removal and disposal of the spent limestone chips, tank cleaning and replenishment with new limestone chips.  Some of the tanks are tall and narrow, making access to the limestone chips difficult, especially near the tank bottom. Current procedures involved small shovels and unnatural body positions to try to reach the bottom-most material.  A better way had to be found.

The customer came across the EXAIR website and found the Line Vac product line. After watching the demonstration video, he knew he had found his solution!  The Line Vac is a compressed air operated device that turns any hose or tube into a powerful in-line conveyor. Based on the height of the tanks and the size and weight of the limestone, we agreed the 2″ Heavy Duty Line Vac would provide the power and durability to empty the tanks in a timely manner, and safely and efficiently.  The customer would use a tow behind compressor so that a reliable source of compressed air would always be available.
