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.

Recently, we at EXAIR worked with a major player in the golf ball manufacturing world. As an avid golfer myself, this was an application I could really get a ‘grip’ on and I had the ‘drive’ to propose a solution.
The customer was involved in Research & Development, performing testing on the golf balls through robotic hitting, collection, and attribute measurement. The current set up involved the ball being hit, gravity collection into a PVC tube, and then an operator unhooking the tube, walking it over to and unloading the balls onto a rack, in the same order of hitting. The customer wanted to eliminate the manual task of the tube handling and have the balls delivered directly to the rack area. The transfer would need to be 15′ vertically, then 15′ horizontally, before dropping down to table level. A typical rate is only 5 balls per minute. This is a perfect application for the Line Vac, a compressed air operated conveyor.
EXAIR had previously tested golf ball conveyance, as seen in the Line Vac video below (at the 1:53 mark) where golf balls are conveyed 100′, at only 30 PSIG of supply pressure.
To present the best solution to customer, we had 2 dozen golf balls sent to us, and we set-up and simulated the actual conveyance conditions of 15′ vertical and 15′ horizontal travel. We found that the balls could be conveyed at only 20 PSIG of supply pressure, when presented one at a time. When the inlet was flooded with golf balls, simulating a worst case condition, the Line Vac was able to perform the conveyance at 60 PSIG. Operation at 80-100 PSIG is possible providing a operational safety factor.
The customer was impressed with the results and has implemented the model 6984 – 2″ Aluminum Line Vac Kit into the process, making the process more efficient.
We have a team of Application Engineers that are ready to review your process and application, and help to determine if an EXAIR Line Vac can convey your material at the distance and rate desired. We may even have you send in small sample of the material, and we can set-up, test, and share the results with you.
If you have questions about Line Vacs, or would like to talk about any of the EXAIR Intelligent Compressed Air® Products, feel free to contact EXAIR and myself or any of our Application Engineers can help you determine the best solution.
The EXAIRLine Vac is a tried and true device for conveying parts, materials, and waste – with no moving parts. The list of successfully conveyed materials in the application database is far reaching – including plastic pellets, scrap/trim, chips, pills/tablets, shavings, sawdust and granules.
The Line Vacs can be used for more than conveying large amounts of material from A to B. Recently, one of our automation customers found an application for the Line Vac in the design and manufacture of a custom fill machine. The machine was commissioned to fill small, plastic cups. To move the cups from the material staging area to the filler processing area, (10) of the 2″ aluminum Line Vacs were used. Using a sensor to measure the stack height in each tube, the compressed air is triggered on/off to transfer a group of cups over to the filling area. See photo below-
Other types of applications that Line Vacs have been used for include pick and place, small space ventilation, fine powder dispersion and light vacuum generation. Another popular use is to integrate into a machining process for waste removal of chips, shavings, and waste removal.
The Line Vacs come in (3) types- Standard, Light Duty and Heavy Duty. Also, (3) different end connections are available including smooth bore, threaded, and the new sanitary flanged. Depending on the model type, materials of construction may include aluminum, type 303 and 316 stainless steels, and a hardened alloy. Special high temperature versions are available with temperature ratings up to 900°F (482°C.)
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

Recently, I was working with a customer looking for a Premium Reversible Drum Vac and wanted it shipped to the Northwest Territories of Canada – which we could do! It got me to thinking, what are the farthest US state and territory locations EXAIR has shipped to in the North, South, West and East directions. I ‘scoured’ the records and came up with these.
Furthest North- We have shipped to Prudhoe Bay, Alaska. Most recently, believe it or not, we shipped a NEMA 4X Cabinet Cooler to an Oil and Natural Gas Exploration Company. Goes to show that even the coldest environments still have the need to provide cool, clean, dry air to cool and protect electronics in electrical enclosures.
Furthest South – We have shipped to the US Territory of Puerto Rico, city of Santa Isabel. An Aerospace company needed a strong, laminar blast of air and utilized a 6″ Stainless Steel Air Knife. An Air Knife offers a quiet, efficient way to clean, dry or cool parts, webs, or conveyors.
Furthest West- We have shipped to the US Territory of Guam. The local University ordered a model 1111-4 Super Air Nozzle Cluster, for a good strong blast of air flow for a cleaning operation. The model 1111-4 delivers 3.2 lbs of force, at just 82 dBA of sound. A safe and efficient nozzle for blowoff operations.
Furthest East- We have shipped to Eastport, Maine. The customer in Eastport ordered a Line Vac and a section of Conveyance Hose. The Line Vac is a great tool for conveying large volumes of material over long distances, through a standard hose or tube. The compact design features large throat diameters for maximum throughput capability.
It was interesting to look back and see all the places that EXAIR has shipped. We have customers from all over the globe. If you are outside the of 50 US States and Canada, we have a dedicated team of International Application Engineers that will work with you to select the best EXAIR product for your process and application, and direct you to your local International Distributor.

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.
