Air Operated Conveyors (Line Vac)

Convey parts, materials, waste - WITH NO MOVING PARTS!

What is The Line Vac?

A fast, low cost way to convey:

  • Plastic pellets
  • Scrap trim
  • Textiles
  • Bulk solids
  • Food products
  • Chips
  • Paper
  • Pills/tablets
  • Small parts
  • Shavings
  • Sawdust
  • Granules

EXAIR's compresed air operated Line Vac connect to standard hose or tube to create a powerful in-line conveyor. The compact design features large throat diameters for maximum throughput capability.

Eleven sizes in Aluminum and ten in Stainless Steel are suited to a wide variety of transfer applications.

Why The Line Vac?

Line Vac conveyors are ideal for moving large amount of material over long distances. A small amount of compressed air is injected through directed nozzles to produce a vacuum on one end and high output flows on the other, with instantaneous response. The material flow rate is easily controlled with a pressure regulator. No Moving Parts or electricity assures Maintenance Free operation.

How The Line Vac Works?

Compressed air flows through the inlet (1) into an annular plenum chamber (2). It is then injected into the throat through directed nozzles (3). These jets of air create a vacuum at the intake (4) which draws material in and accelerates it through the unit (5) for conveying over long vertical or horizontal distances.

Line Vac Conveying Rates

The actual conveying rate is affected by the size, mass and geometry of the part to be conveyed along with the length, lift and number of bends in the hose, tube or pipe. These variables make it difficult to determine the exact conveying rate for any product, however, our application engineers can assist you by comparing the material you want to convey with something that has already been tested.

  • Filling operations


  • Compact
  • Quiet
  • No Moving Parts
  • Fits standard hose or tube
  • Aluminum or stainless steel
  • Eleven sizes
  • High throughput capability

Selecting The Right Model

Line Vac is available in a wide range of sizes to fit your application. Some of the criteria used to select the proper model are:

  • Diameter of parts being conveyed
  • Diameter of hose or tube
  • Rate (weight or volume)
  • Stainless steel (Type 303 and 316) or aluminum

Aluminum is the economical choice for general purpose conveying. Our standard stainless steel models (Type 303) offer good corrosion resistance and are ideal for food service, abrasive or corrosive applications. For critical applications including certain foods and pharmaceutical products, Type 316 stainless steel models provide excellent corrosion resistance.

The High Temperature Line Vac models are suited for temperatures up to 900°F (482°C). Frequently used for sampling hot flue gases, this High Temperature Line Vac can resist back pressure from long pipe lengths with numerous bends.

WARNING: Do not use with any material that can become an explosive mixture!

Line Vac Drum Cover

EXAIR's fine mesh non-woven Drum Cover is built to fit over the top of 55 or 30 gallon drums. The breathable material allows the air from Line Vac air operated conveyor to circulate, whether moving material in or out of the drum. The cover prevents contamination of your material and keeps material from escaping the drum which keep your work invironment cleaner and safer. Since it is fabricated to fit 55 or 30 gallon drums, it is simplest of solutions when needing a containment vessel for your transferred scrap, trim, waste, parts, chips or pellets. It is suitable for Line Vac conveyance hoses from 3/4" to 3,4" outside diameters and comes complete with hose clamps and a durable spring buckle strap for quick and easy installation.
