It doesn’t say things like we have 99.9% on time shipping for 23 years in a row, or that we constantly add new products to our 15 product lines which help you solve even more problems in your facility. It doesn’t say order by 3pm and you can expect same day shipping or any of the nice things our customers say about their experience with us:
“Great Service!!!” – Carlos H., metal packaging manufacturer
“Very prompt and answered all of my questions!” – Michael W., connector and sensor manufacturer
“Very professional, knowledgeable” – Jose P., CNC machining and metal services
“Great info about [the] product I asked about…..very very helpful” – Joe O., home air conditioner manufacturer
But it does say a lot of other things you can expect when doing business with EXAIR.
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.

Piping systems have been a hallmark of human civilization for almost as long as people have been living in community with each other. Evidence of complex earthen pipe systems, with flanged fittings & asphalt sealants, date to 2700 BC. These were used for crop irrigation, potable water distribution, and wastewater removal in ancient civilizations from the Mediterranean to the Far East.
Over the centuries, new ways to use pipe led to new ways to make pipe. Scientists and engineers figured out ways to make pipe stronger, lighter, cheaper, and in a variety of materials. One of the more recent milestones is the development of sanitary piping and fittings. The stringent cleanliness controls in certain industries (food and pharmaceutical, I’m looking at you) require highly corrosion resistant materials of construction. The inside & outside surfaces of the pipe have to be finely finished so that they can be thoroughly and positively cleaned, with no crevices, “nooks & crannies,” etc., for material to gather or cling. And since regular cleaning & sterilization is performed, the fittings must be able to be made & unmade in a manner that still provides for positive sealing when the system is restored to operation.
EXAIR Line Vac Air Operated Conveyors have always been well suited for applications like this. With their open, unobstructed throats and smooth bores, they’re intuitively easy to clean, by design. And we’ve made them, for years, in Type 316 Stainless Steel – the preferred material of construction for many food and pharmaceutical applications. Many users in these industries were able to install them in sanitary piping systems by welding the flanges on our Stainless Steel Line Vacs, or by installing adapters on our Threaded Stainless Steel Line Vacs.
In the spring of 2017, EXAIR released the Sanitary Flange Line Vac with those same users in mind – eliminating the need to weld or thread flanges onto existing products. They feature the same conveyance power as our Stainless Steel Line Vacs, and can even be modified to meet Heavy Duty Line Vac performance, if needed. There are four sizes: 1-1/2″, 2″, 2-1/2″, and 3″…which covers the most popular size range of sanitary pipe systems.
While the sanitary piping systems are certainly most often found in those cleanliness-critical food & pharma type applications, other users incorporate them because of the smooth, continuous bore of the pipe and fittings, as opposed to a threaded pipe system, where the OD of the pipe threads into the ID of the fittings, causing a “step” in the throughput. Because sanitary fittings mate via face-to-face flange seals, this eliminates that “step” which can make for a catch-point for certain items. It’s for this very reason that a popular ammunition manufacturer uses sanitary pipe systems to convey shell casings…because they tumble with such turbulence in the air flow, they are especially prone to hanging up on any kind of catch-point. So, they use sanitary piping & fittings, long radius elbows, and EXAIR Model 161150-316 1-1/2″ Sanitary Flange Line Vacs.
EXAIR has a wide selection of engineered compressed air products that are “textbook” solutions for certain applications, but also make perfect sense for use in places you might not have thought of. If you have a bulk material conveyance operation you’d like to discuss, give me a call.

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.
