If you have questions about the Sanitary Line Vac, 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.

Do you have operators climbing steps to dump bags of material into hoppers? Do you need a faster way to remove scrap from a process? Do you have budgetary constraints in trying to move material from punt A to point B? If you answered yes to any of these, EXAIR may have a simple solution. We manufacture an air-operated conveyor that does not have any moving parts, has a very compact design, and generates a high throughput capacity. They can attach easily to standard hoses, pipes, or sanitary flanges to convert your piping system into a powerful conveying system. EXAIR manufactures these air-operated conveyors and trademarks them as Line Vacs™.
EXAIR Line Vacs use a small amount of compressed air to generate a powerful vacuum by a Venturi effect. The unique design of the generator creates a high velocity of air to create a low pressure on one side and a powerful thrust on the other. The Line Vac can pick up and move solid material from light and fluffy batting to steel components. They can transfer product horizontally up to 100 feet (30 meters) away and vertically up to 20 feet (6 meters) high. You can watch a video on the operation of a Line Vac HERE. Compared to other vacuum or conveying systems, the EXAIR Line Vacs are very quiet, rugged, and powerful. EXAIR makes a variety of Line Vacs in different sizes, styles, and materials to best fit your application.
The standard Line Vac is the most versatile product in this family. EXAIR stocks a wide range of sizes, materials, and styles for targeting the best solution for moving material. We have two types of connections, slip-on ends for hose connections and threaded ends for pipe connection. EXAIR can swap the connections with a slip-on hose on one end with a threaded connection on the other. They range in diameters from 3/8” (10mm) up to 5” (127mm). We manufacture the Line Vacs in aluminum, 303SS, and 316SS; but don’t let that deter you if your need them manufactures in any other type of material. We have high temperature models that can withstand temperatures up to 900 deg. F (482 deg. C). These Line Vacs work great in applications for loading plastic pellets in hoppers, discarding scrap pieces, trim removal, and transferring material. If an operator has to carry a container of dry material and climb stairs, a Line Vac could be a much better alternative.
The Heavy Duty Line Vacs are made from a hardened alloy steel for abrasion resistance. The generators inside these Line Vacs are more powerful than the standard models; so, that they can convey heavier materials at higher conveyance rates. They can reach rates as high as 40 lbs./min. (18.2Kg/min) of material. With the hardened alloy construction, they are great for sand blasting applications, ceramic, glass and steel shot. They are manufactured with inlet and outlet connections for ship-on hoses or threaded pipes. EXAIR stocks the Heavy Duty Line Vacs in the range from ¾” (19mm) to 3” (76mm) for both hose and NPT connections. These Line Vacs are our most powerful design with great wear resistance.
On the other end of the Line-Vac spectrum, EXAIR also created the Light Duty Line Vac. They use much less compressed air than the other Line Vacs which work great for moving lightweight materials over short distances. They can also be used for removing smoke and fumes from a work area. The Light Duty Line Vac ranges from ¾” (19mm) up to 6” (152mm) diameter for slip-on hose connections. This two-piece design provides an effective way of moving material at a lower cost. It can be used in applications like hopper loading, fiber tensioning, filling operations, and smoke removal. For moving material within a short distance, the Light Duty Line Vac could be the proper product to use.
Our latest engineering design within the Line Vac family is the Sanitary Flange Line Vacs. They can fit within sanitary piping systems to convert pipes into a useful conveyor for bulk material and waste removal. They use an ISO2852 flange for easy disassembly and cleaning to reduce bacterial entrapment. They ae made from 316 stainless steel material for superior corrosion resistance. They come in four different sizes to fit the sanitary flanges from 1-½” up to a 3” flange. For sensitive applications where cleanliness is a major requirement, the Sanitary Flange Line Vac are manufactured for these conditions.
With all of the EXAIR Line Vacs above, they can be sold as kits. A kit will include a filter, regulator and a bracket. (A bracket is not sold with the Light Duty Line Vac kits.) The filter will help keep the Line Vac clean as well as the product that it is conveying. The regulator is a great tool to vary the conveyance rates for better control. The bracket helps to mount the Line Vac to a sturdy base for support. A useful accessory to conveniently hide the compact Line Vac for ease of use and operation.
If you need to convey solid materials in a quick and easy way, an EXAIR Line Vac could be a solution for you. We have them in a variety of formats to match your application. They are compact, quiet, and simple to use without any moving parts. As compared to a conveying system which is bulky and rigid, the Line Vacs are flexible and inexpensive. Ergonomically, they can save the back-wrenching labor of picking up bags, climbing stairs, and dumping material into hoppers.

For over 34 years, EXAIR has been manufacturing Intelligent Compressed Air Products and we understand that there may be “special” cases where a stock product isn’t going to fit a specific need or requirement. What sets us apart from our competition is that we are able, with a little help from the customer, to engineer and manufacture custom made products, like the Line Vac Conveyors, to fit the specific demand of a unique application.
A few examples are shown below:
This special 3/4″ Stainless Steel flanged Line Vac is being used to remove acidic vapors after a silicon wafer etching process. The flanged design allowed the user to direct mount to the machine, eliminating the need for other expensive modifications.
A customer was needing a special Line Vac for a chloride wash area due to the aggressive chemicals. We were able to make a custom 1-1/2″ Line Vac in PVDF construction for corrosion resistance and QF flanges for easy maintenance and cleaning.
This special funnel shaped Line Vac is being used in a a small packet filling operation. The unique design assured for a clog free process by keeping the granulated material moving through the tube.
A company was needing a miniature version of a Line Vac to remove microscopic debris in an integrated circuit chip making process. The barb fittings allowed for easy installation into the small work place.
These are just a few examples of how we are able to meet the demands of a wide variety of extraordinary processes. Whether you are looking to move “common” materials like plastic pellets or maybe something “off the wall”, chances are we have the resources to provide an engineered solution to fit your need. Our application engineers are standing by, so give us a call and let us put our expertise to work for you!
If you follow our blog, you know that over the past 2 years I have posted a few blogs related to coaching my oldest son’s youth football team. Well it’s that time of year again as we enter our 3rd season with the team. Each year, the athletic boosters put together a “Spirit Wear” package for the players, parents and coaches to purchase that typically includes a t-shirt, with some type of motivational message, and matching shorts. Last year the slogan was “Out Work, Out Hustle, Out Hit”, and in all honesty, I really didn’t like it all that much. This year’s shirts have the motto “PrACTice Like A Champion” which plays right into the mentality our coaching staff tries to instill in our young players.
The head coach and I attended a youth football coaching clinic over the winter that was put on by our local NFL team, the Cincinnati Bengals, to further develop skills to help our players. During the clinic, one particular NFL positions coach used the term I.M.P.A.C.T. as an acronym for “I Might Provide A Critical Thought, Teaching or Technique”. This message really hit home for us with not only how we communicate with our players but also how we interact with each other, referees, parents, opposing coaches and players, etc. We are dealing with 8-9 year old kids who are very impressionable so how they see their leaders (coaches) act can play a large role in their own behavior.
Over and over we remind the kids during practice and in games that win or lose, we are going to respect the game and play it the right way. Too many times you see professional and sometimes collegiate athletic teams disrespect their respective sport by cheating or playing “dirty” to try and gain a competitive edge. Heck, during some of our own peewee games we’ve had opposing players get frustrated and try to take out key players or have coaches instruct their players to take a cheap shot after a play has been whistled dead. Now, I’m as competitive of a person as there is, but I will NEVER understand this type of mindset. These are young kids, playing a GAME. At the end of the day, you put your uniform on, line up and let the game play itself out – may the best team win. For our team, this year’s motto “PrACTice Like A Champion”, we hope is going to serve more purpose than just relating to our football program but rather as a way they go about each day.
While we don’t compete in sports at EXAIR, we do put in the “Practice” behind the scenes in being “Champions” to our industry. We are constantly working on developing new products to support our customer’s ever changing needs. For example, we recently released our NEW Catalog 31 which features several new products like our VariBlast Safety Air Guns, Sanitary Flanged Line Vac Air Operated Conveyors and our NEW Gen4 Static Eliminators.
If you need assistance with selecting any of these new products or to “tackle” a particular application, contact one of our team members and let us put our championship mindset to work for you.
EXAIR’s Air Operated Conveyor product line just expanded, making it easier than ever for a wide range of industries to solve an ever growing range of bulk conveyance applications. Before we get to that, let’s look at just how versatile the Line Vacs are:
The standard Line Vac has been making bulk conveyance as easy as it could get for years now. They come in sizes from 3/8″ to 5″, and all you need is a hose to move material from point A to point B.
If you need high power for higher conveyance rates, longer distances, or very dense material, the Heavy Duty Line Vacs are what you’re looking for.
Light Duty Line Vacs are aimed at applications implied by the name…when smaller volumes of low density material don’t require all the head & flow generated by the standard or Heavy Duty models, these are as quick & convenient as the rest, and come in sizes from 3/4″ to 6″.
The newest additions to the Line Vac family are the Type 316 Stainless Steel Sanitary Flange models:
These are especially popular in pharmaceutical, food, and brewing applications.
