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.)
When it comes to conveying bulk materials like pellets, grains, powders, etc., you’ve got plenty of choices: Mechanical conveyor types, like bucket, auger, and cleated belt conveyors can move product as far as you want, and as quickly as you want…they can be made as long as you want, and as big & fast as you want. “Fast” as in conveyance rate, that is. Lead time, including engineering, design, fabrication, and installation, can be months.
Air operated conveyors are quite popular too, and the dense phase models can move a lot of material a great distance, and quickly. Like the mechanical types, they have a wide range of economy to scale…and the price tags to prove it. Medium- and dilute-phase pneumatic conveyors are less complicated in design, which brings us to the heart of today’s blog.
EXAIR Air Operated Conveyors, or Line Vacs, are the simplest of all: the Line Vac itself used compressed air to generate a “pull/push” to draw material into the suction, and propel it through the discharge. We have a variety of models to choose from, but our focus today will be the Heavy Duty Line Vac.
EXAIR Heavy Duty Line Vacs are the workhorse of our Air Operated Conveyors product line. Consider their advantages:
*Made of a proprietary hardened alloy, they offer superior abrasion resistance & durability. They’re ideal for shot blast and tumbling media…the very stuff that’s MADE to wear metal surfaces down…and it’s no problem for the Heavy Duty Line Vac.
*Heavy Duty also means higher power, which means higher suction heads (up to 2-1/2 times increase) and conveyance rates (up to 11 times greater.) Oh, and that blasting shot & tumbling media I mentioned? Standard dilute-phase conveyors may have trouble moving that at all.
*Like our Standard Line Vacs, the Heavy Duty models’ Kits come with a Mounting Bracket for ease of installation, an Automatic Drain Filter Separator to keep the air clean & dry, and a Pressure Regulator so you can ‘dial in’ the performance you need.
*Also like our Standard Line Vacs, the Heavy Duty models use common sized conveyance hose (3/4″ to 3″ ID) and are also available with male NPT threads (3/4″ to 3″ as well) if you want to hard pipe them.
If you’re looking for a simple, durable, and powerful conveyor system, look no further than the Heavy Duty Line Vac. Give me a call if you’d like to discuss your application and/or product selection.

Today I worked with a customer that manufactures a wide variety of material handling equipment including coil unwinders. The engineer was calling because there was a special project for a coil unwinder that could handle a waste piece of paper trim. As the metal coil is being unwound for delivery to a metal processing machine, the protective paper is pulled off and was to be collected into a waste receptacle for easy handling and disposal/recycling. The engineer was hoping to replicate an existing system that used a hybrid blower system, with an extra compressed air nozzle, but in a simpler form.
We proposed the use of the 4″ Light Duty Line Vac– shown below.The Light Duty Line Vacs offer an effective way to convey small and light materials a short distance. Like the standard Line Vac, the Light Duty Line Vac converts an ordinary hose or tube into a conveyor for scrap, trim, and bulk materials.
When the process involves moving low volumes of materials over short distances, the Light Duty Line Vac is a great choice. The simplified (2) piece design offers effective conveying at a lower cost. As an added plus, the compressed air consumption is lowered to levels commensurate with handling the lighter materials, at lower volumes and short distances. Using a pressure regulator to control the supply air allows for tuning of the transfer rate, and keeps air usage to the minimum amount needed.
The Light Duty Line Vacs are available with inlet/outlet diameters from 3/4″ up to 6″. With no moving parts, maintenance free operation is assured.
For other larger materials, higher transfer rates, corrosive environments, or abrasive materials, take a look at the other EXAIR Line Vac offerings including the aluminum, 303 and 316 stainless standard Line Vacs, the aluminum, 303 and 316 stainless steel Threaded Line Vacs, high temperature models, standard and threaded Heavy Duty Line Vacs, and lastly the new Sanitary Flanged 316 stainless steel type.

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

Even if you’re a casual reader of our blogs, you already know that EXAIR Application Engineers LOVE to preach efficiency in the use of compressed air…it’s our “bread and butter;” the very nature of our business. This year, we’re celebrating thirty-five years of leading the way in the development of efficient, safe, and quiet compressed air products. Our track record of success as a solutions provider across a diverse range of industrial and commercial applications is well documented in our blogs, as well as Knowledge Base and Case Study Libraries. We devote considerable resources (engineering, research & development, product testing, etc.) to making certain that EXAIR Intelligent Compressed Air Products cost less to operate, and perform better, than whatever you’re using right now.
Strange as it may seem, though, sometimes our products are EXTREMELY popular in cases where they INCREASE a facility’s consumption of compressed air…by replacing something that DOESN’T use compressed air at all:
*I’ve written before about how our Large Maximum Cold Temperature Vortex Tubes have replaced liquid nitrogen rigs in freeze sealing operations. Now, a Vortex Tube directs a portion of its air supply to (usually) unusable hot exhaust, in order to generate the usable flow of cold air. When compared to the costs of liquid nitrogen and the resources involved to get it where it needs to be, though, the cost of the compressed air needed to operate the Vortex Tube is indeed the practical solution.
*Line Vacs are probably THE prime example of the value of using compressed air where it wasn’t used before…replacing a “bucket and ladder” operation:
*Then there are the situations that just come down to time. In large spaces, our Super Blast Safety Air Guns can be used to “sweep” the floor in a fraction of the time it takes an operator with a push broom.
To make a long story just a little bit longer…if you’re using compressed air, you can use it better with EXAIR’s engineered compressed air products. And there are plenty of practical applications where you’re not using compressed air right now too. If you’d like to find out more about either one, give me a call.
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.
