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.)
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

Convey parts, materials, and waste – with no moving parts!
The Line Vac is a fast, low cost way to convey pellets, scrap trim, textiles, bulk solids, food products, chips, and much more. Simply connect to a standard hose, tube, or pipe and a powerful in-line conveyor is created.
Available in (4) materials – aluminum, 303 and 316 stainless steels, and a special hardened alloy, and (3) end connection types – NPT threaded, smooth bore, and the new sanitary flanged. Sizes range from 3/8″ up to a 6″. It is certain that an available Line Vac option will meet your process criteria.
For lighter materials and short conveyance distances, the Light Duty model is ideal, and for the most abrasive and heaviest materials over longer distances, the Heavy Duty style is available.
The Line Vacs offer many safety benefits, including eliminating the dangers of lifting heavy sacks and climbing ladders to fill hoppers, and with the 316 stainless steel sanitary flanged Line Vacs, food materials are kept enclosed and and separated and provides ease of cleaning.

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.

Recently, I worked with a customer that was looking for a way to make a difficult job easier, reducing stress and strain on the body and preventing injury. The customer was in the Environmental Services & Hazardous Waste Management area and regularly was called out to service acid neutralization tanks. These are commonly found in hospitals, laboratories, and schools, to neutralize lab wastewater before it is discharged to the sanitary sewer. The systems typically utilize limestone chips to aid the in process.
Periodic maintenance includes the removal and disposal of the spent limestone chips, tank cleaning and replenishment with new limestone chips. Some of the tanks are tall and narrow, making access to the limestone chips difficult, especially near the tank bottom. Current procedures involved small shovels and unnatural body positions to try to reach the bottom-most material. A better way had to be found.
The customer came across the EXAIR website and found the Line Vac product line. After watching the demonstration video, he knew he had found his solution! The Line Vac is a compressed air operated device that turns any hose or tube into a powerful in-line conveyor. Based on the height of the tanks and the size and weight of the limestone, we agreed the 2″ Heavy Duty Line Vac would provide the power and durability to empty the tanks in a timely manner, and safely and efficiently. The customer would use a tow behind compressor so that a reliable source of compressed air would always be available.
The Heavy Duty Line Vacs are available in sizes from 3/4″ up to 3″ in both smooth end and threaded connections for use with hose or pipe for conveyance.

There are many curious sayings from history that are still part of our vernacular, and whose origins are debated. Examples are ‘Spill the Beans’ and ‘Bite the Bullet.’ One of my first supervisors liked to use the expression ‘Don’t throw the baby out with the bath water.’ Initially, I didn’t quite understand what was meant by this, and then wasn’t sure it was relevant in some instances. Fast forward many years, I hadn’t thought too much about it, but for some reason, the phrase recently came back into my thinking.
Today the phrase generally means not to get rid of something good when getting rid of something bad (when throwing out the dirty bath water, you don’t want to throw out the baby, too!) As I look back to the supervisor that used it, it was for situations where the solution was within grasp, but due to recent shortcomings it may seemed out of reach. Scrapping the whole thing (the baby and the bathwater) and trying something new would not be the favorable way to proceed.
I remembered this phrase when recently a customer called in about the 3″ Line Vac they were using. It was performing OK, but just was’t doing what they had hoped. They asked if it was still returnable under the 30 day guarantee (it was) and how to start the return process.
While we aim to make the return procedure simple and efficient, we will most likely ask a few questions. We’ll ask ‘what are trying to do?’ ‘Can you send in any photos of the installation’ (we solve lots of issues by seeing something that can be easily remedied) and certainly we will ask ‘about the compressed air supply.’ In the recent customer call, the customer was trying to convey dog food, a distance of 25′ vertical and 18′ horizontal – a fairly challenging distance, but not impossible. A photo could be sent in if needed and then the discussion turned to the compressed air supply. It was determined that the compressed air supply line was undersized for the 68.5 SCFM of 80 PSIG compressed air needed to for the Line Vac to operate to its full capability. We reviewed the Installation and Maintenance Guide and suggested the proper pipe and air hose sizing for this installation. Armed with this new knowledge, the customer set about to modify the installation.
I got an email later that day from the customer. Results were dramatically improved! Average of first measured trials yielded 50 lbs of material in 46 seconds, one of the fastest conveyance rates recorded for those types of distances. Customer was pleased and was looking forward to keeping the unit and getting the benefit that was expected.
In this case, the baby was not thrown out with the bath water.
