Standard Line Vac

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

Line Vac - uses a small amount of compressed air to convert ordinary pipe, hose, or tube into a long distance conveyor.

  • No Moving Parts to clog or maintain
  • Ideal for hopper loading, fiber tensioning, trim removal, and material transfer
  • Available in aluminum and stainless steel for hygienic applications
  • Complies with OSHA noise and pressure standards

EXAIR's compressed air operated Line Vac connects to standard hose to create a powerful in-line conveyor material handling system.

Unlike belt or screw type conveyor equipment, Line Vac conveyors are ideal for moving large volumes of material over long distances without clogging or jamming. The material flow rate is easily controlled with a pressure regulator. An optional bracket permits easy mounting. NO MOVING PARTS or electricity assures MAINTENANCE FREE Operation.

Sizes will fit from 3/8" to 5" inside diameter hose. Available in aluminum, type 303 stainless steel or type 316 stainless steel.

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.

Here are some case studies:

The Problem: Injection molding machines transform plastic pellets into various plastic products. The pellets are gravity fed from a hopper on top of the machine. The “bucket and ladder” method of replenishing the hopper was inefficient and expensive.

The Solution: A Model 6982 1-1/4" (32mm) Line Vac Kit was used to convey the pellets up to the hopper. The mounting bracket included with the kit was used to secure the Line Vac to the machine. A filter assured no contamination of the plastic material and a regulator controlled the plastic flow rate.



Refilling A Vibratory Bowl

The Problem: A manufacturer of metal products deburrs aluminum sleeves in a vibratory bowl filled with abrasive media. As the parts complete the deburring cycle, they are discharged to a screened bed. The abrasive media drops through the bed and the finished parts roll into a box. Refilling the bowl was a back breaking operation that required repetitious lifting of heavy buckets.

The Solution: A Model 6064 2" (51mm) Stainless Steel Line Vac was installed on the vibratory bowl. In minutes, the media was conveyed back up to the bowl through a hose, without the heavy lifting


Line Vac for Matrix Removal from Labelling Application

The Problem: A manufacturer applies labels to their products. After they have been applied, there is a waste stream that is referred to as “the matrix”. The matrix is the release liner that labels are affixed to in bulk format prior to being used. The normal method for taking up this waste stream was to use a winder. However, after some amount of time, the winder inevitably becomes filled. Once full, the line is stopped and the winder is manually emptied. They needed a better way to dispose of the matrix.

The Solution: The Line Vac presents a unique advantage in that it can pull the matrix from the machine and convey it out to a waste receptacle. This requires no winder, no stopping the line and no emptying. This solution freed up personnel for other tasks and increased production. The compact design and powerful operation of the Line Vac allowed it to be placed close to the generation of scrap, trim, or waste. Its powerful conveying capacity allowed it to transport the material to a remote and central location.

Here are some sample of applications:


A model 6084 2" (51mm) Line Vac transports scrap celophane trim to waste barrel.


1-1/4" (32mm) Line Vac is mounted on a burr removal tool suction the plastic shaving and transport them to a waste container.


High Temperature Line Vacs can resist temperatures up to 482ºC and are available from stock in hose or threaded models.


(2) Model 6083 1-1/2" (38mm) Line Vacs convey rejected metal caps from a fluorescent lamp operation to a scrap bin.


A 316 Stainless Steel Line Vac is used by a pharmaceutical company to convey pills and tablets to a packaging station.


Line Vac move 150 pounds of dense pellets from a large container into a smaller vessel for weight load testing.

Available version:

Threaded Line Vacs - provides the same outstanding performance as the Line Vac with the added benefit of common threaded fastening. The standard threading allows easy attachment to common plumbing pipe and fittings.

What is The Threaded Line Vac?

A fast, low cost way to convey:

  • Plastic pellets
  • Scrap trim
  • Textiles
  • Bulk solids
  • Chips
  • Paper
  • Small parts
  • Shavings
  • Sawdust
  • Granules

EXAIR’s Threaded Line Vac air operated conveyors convert ordinary pipe into a powerful conveying system for parts, scrap, trim and other bulk materials. The Threaded Line Vac attaches easily to plumbing pipe couplers, making it easy to build a complete system using ordinary pipe and fittings available from any home center, hardware store or plumbers supply. Performance is the same as our standard Line Vac.

Threaded Line Vac conveyors are ideal for conveying large volumes of material over long distances. They eject a small amount of compressed air to produce a vacuum on one end with high output flows on the other. Response is instantaneous. Regulating the compressed air pressure provides infinite control of the conveying rate. Models from 3/8 NPT to 3 NPT are available in Aluminum and Stainless Steel, which are suited to a wide variety of conveying applications. An optional mounting bracket permits easy mounting. No moving parts or electricity assures maintenance free operation.

Here are some sample of applications:

A drawer slide manufacturer convey ball bearing with the Model 141125 1-1/4 NPT Stainless Steel Threaded Line Vac to an assembly station.


Plastic color concentrate pellets are added to a plastic extrusion process.
