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!
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:
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.
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.

With 119 distinct Models, EXAIR Line Vacs are used to convey everything from down feather to steel shot. They’re versatile, reliable, durable, and incredibly easy to install and operate. Most applications can be completed using one of our many stock Line Vacs. Additional applications include part transfer, waste or trim removal, hopper loading, filling operations, chip removal and fiber tensioning.
They are available from 3/8″ to 5″ diameters, for use with hose, tube or pipe. Line VAcs have smooth ends for hose or tube. The threaded models use NPT threads from 3/8 NPT to 3 NPT to turn ordinary pipe into an air conveyor! They can also be bought with sanitary flange ends for easy disassembly when necessary for cleaning or maintenance.
Materials include aluminum, Type 303 and Type 316 stainless steel or a hardened steel alloy for moving abrasive materials like garnet, glass, or blasting media.
With that being said, there are always applications that need a special product. And because of that we do make “special” or custom products when the need arises.
For example this Live Vac has the sanitary flange design, but the customer needed it made from a special material so their product passing through it wouldn’t be contaminated by metal. So we did just that, we designed built and shipped this line vac and it worked amazingly well!
Accessories include the transport hose, mounting brackets, filter and regulators. A filtering drum cover is very useful to keep material and/or dust inside, when transporting materials into a drum.
No matter what kind of bulk material you need to move, or what type of special conditions you have. EXAIR has a Line Vac product for it. If you’d like to find out more, give me a call.

With 119 distinct Models, EXAIR Line Vacs are used to convey everything from down feather to steel shot. They’re versatile, reliable, durable, and incredibly easy to install and operate. Consider this list of uses, starting with our smallest Line Vac, and going to our largest:
Model 6058 3/8″ Stainless Steel Line Vacs pull mica from a bulk container and spray it into a mold for making decorative stones, to apply a glittery surface. They used to do it by hand, but the Line Vacs spread it more consistently.
Model 130075 3/4″ Light Duty Line Vacs perform a similar function in a plastic cutting machine, conveying away cut chips and eliminating the need for periodically stopping the machine to clean up.
A medical device manufacturer saw a 50% increase in productivity when they went from removing flash by hand from molded silicon parts to using a Model 6061 1″ Stainless Steel Line Vac to suction it away automatically.
A mining equipment manufacturer reclaims sand from a secondary operation on their green sand molds with a Model 6062 1-1/4″ Stainless Steel Line Vac. This keeps their mold area clean, and has eliminated waste in production.
Model 151150 1-1/2 MNPT Heavy Duty Threaded Line Vacs, fitted into black iron pipe systems, reclaim hot metal chips from a deep channel milling machine, automating the transfer to the recycling hopper. This eliminated the risk of lifting AND burn injuries from the manual handling of the hot chips.
Model 6084 2″ Aluminum Line Vacs vacuum trim scrap from custom label making machines to a central scrap bin, keeping the floor clean, and keeping operators from having to empty individual bins at each machine.
A Model 6065 2-1/2″ Stainless Steel Line Vac conveys rejected peanuts (identified and segregated by a vision sorting machine) from the catch pan to a large collection hopper. This is hauled away at the end of each shift, instead of an operator paying constant attention to the catch pan.
Model 161300-316 3″ Sanitary Flange Line Vacs replaced mechanical conveyors in a grain mill, incorporating a totally enclosed Clean In Place (CIP) system. This greatly reduced contamination controls when the product was openly conveyed, and actually increased their conveyance rates of their bulk grains.
A Model 6087 4″ Aluminum Line Vac conveys an additive (in pellet form) into an asphalt mixer, replacing an auger conveyor that left product in the hopper and would clog regularly, resulting in messy spills.
A company that recycles spent ammo from gun ranges uses a Model 6088 5″ Aluminum Line Vac to convey the granulated rubber backstop material into their truck. After the ammo is separated, they use the Line Vac to replenish the granulated rubber into the backstop.
A Model 130600 6″ Light Duty Line Vac conveys linen squares (mostly 12″ and 24″ square) through the main header of a sorting operation in a commercial laundry facility. The system also incorporates several Model 120024 4″ Super Air Amplifiers in individual “pickup” branches.
No matter what kind of bulk material you need to move, EXAIR has a Line Vac product for it. If you’d like to find out more, give me a call.
