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 also 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, garnet, tumbling media 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.
The performance of the Heavy Duty Line Vac’s is nothing short of amazing! With vacuum ratings between -144 to -20 inches of water column, it is more than likely there is a Heavy Duty Line Vac model that will suit your application.
Models range from 3/4″ OD to 3″ OD either in smooth bore or NPT threaded models for the ultimate in versatility. The table below shows the different Heavy Duty Line Vac Models and their respective recommended kit, which includes a pressure regulator for fine tuning performance, filter separator to keep the compressed air supply clean and a mounting bracket.
EXAIR started writing Blogs in 2008. Since then, we have written well over 2000 Blogs. There is a ton of information in our Blog section on the website. There is most likely a Blog or 10 written about nearly each one of our products. These are primarily written by application engineers that know a thing or two about our products. There are also many application Blogs, that may be very relatable to what you are doing. When you journey to our Blog page (or simply click Blog form EXAIR.com), simply type in a key word or two in our search bar. This search bar is located just below the first row of published Blogs on the right hand of the screen, here is a screenshot of that section (right). You can also choose to follow our blog here as well.
As application engineers, we get asked questions every day. Many of these questions are best answered in one (or more) of these 2000+ Blogs. Many times a picture or video can answer your questions much more precisely than a quick conversation or an email. Many times we will send you a blog link to help. Drawing from my own experience, and asking the other Application Engineers for their lists, I wanted to put our most referenced blogs in one helpful location. I’ve categorized these the best that I can, and hopefully this will be a useful resource for you today, and in the future.
OPTIMIZING YOUR COMPRESSED AIR SYSTEM
This is one of the key sections to our blogs. One of our main goals is to help you optimize your system. Here are 6 blogs that go into detail on each of these key points:
This is a product line that has a lot of maintenance questions, probably because these products are used to clean up dirt, and where there is dirt, there can be problems, clogs and leaks:
One of the most common questions we have concerns the Reversible Drum Vacuum (RDV) refurbishment Blog. The RDV is used on the Reversible Drum Vac, and the Chip Trapper products. We offer a refurb service for a fee, but most of the time you can do this on your own by watching and following this blog: Cleaning the Reversible Drum Vac
There are many more blogs and videos at your disposal. This is just a recap of many of our most used, most viewed and most helpful for the day-to-day conversations that happen here at EXAIR. If you have ideas for new blogs – we would love to hear that as well. Please feel free to reach out at any time for more information on any of our intelligent compressed air products.

EXAIR’s Line Vacs are the ideal low-cost solution for bulk material transfer or trim and scrap removal. Available with NPT threaded connections, EXAIR’s Threaded Line Vacs allow you to convert ordinary pipe into a powerful conveying system for parts, scrap, trim, and other bulk materials. With performance identical to that of the Standard Line Vac, the Threaded Line Vac is available in sizes ranging from as small as 3/8 NPT and up to 3” NPT. There’s a suitable Line Vac for most standard sized NPT pipe common in any industrial facility.
The Threaded Line Vac is available in a range of different materials: Aluminum, Type 303 Stainless Steel, Type 316 Stainless Steel, and as a Heavy Duty conveyor constructed of a hardened alloy steel for use in abrasive applications. Where most materials or hard anodized coatings wear out or wear off over time, the Heavy Duty Line Vac is the ideal solution for heavy and abrasive materials. In addition to being abrasive resistant, the Heavy Duty Line Vac is also more powerful and suitable for longer vertical and horizontal transfer distances.
Each style of Threaded Line Vac is also available as a High Temperature option. By replacing the traditional o-rings with graphite seals, we’re able to provide a solution capable of withstanding temperatures up to 900°F!!!
The conveyance rate through the Line Vac is infinitely adjustable by regulating the air pressure supplied to it. At lower pressures, the conveyance rate (and air consumption) will decrease. At higher pressures, the conveyance rate will increase. If you have a Threaded Line Vac with the standard performance but need just a little bit more, the option also exists for a High Power unit that would match the performance of the similarly sized Heavy Duty. This can be ordered from the factory with an “HP” prefix, or modified yourself. Check out our video to see just how simple it is to get more out of your Threaded Line Vac.
With all sizes and materials on the shelf and in stock, we’re able to get a solution out to you quickly. We’ll ship out the very same day for stock orders received by 2:00 ET. Backed by our Unconditional 30 Day Guarantee, you’re able to make sure it is the right solution for you before committing to keep it. If you have an application that could be better served with an in-line pneumatic conveyor, give us a call. We’ll be happy to help you determine the most suitable size for the application.
EXAIR’s Line Vac Air Operated Conveyors provide an efficient method of converting ordinary pipe, hose or tubes into powerful in-line conveyors. To accommodate the wide variety of unique problems manufacturers face, EXAIR has the ability to customize and tailor Line Vacs to different specifications. Certain processes may require customizations like unique sizes, shapes and materials in order for the product to be a perfect fit for their system. EXAIR will work in collaboration with the customer to fabricate the best possible Line Vac solution for easy and efficient conveyance.
I worked with a customer to design a special Line Vac. They needed 3” ANSI 150# Flanges on a 3” PDVF Line Vac. So, we had a special material with special ends to fit their specific need. The PVDF with Hastelloy hardware was for chemical resistance, and the flanges would mount into their piping system. As with many of our Line Vacs, we can turn a normal piping system into a conveyance system for waste, parts, or bulk materials. For this customer, they needed a backup system for a fume hood. With electrical vacuums and blowers, loss of power or motor failures can cause a momentary lapse in fume removal. Since the chemical material that was used in the hood was dangerous, they needed a reliable source to extract the fumes. Since any Line Vac does not have moving parts or require electricity, they are durable, reliable and require little to zero maintenance. The Line Vac only uses compressed air or gas to make them operate. For this customer, they attached nitrogen to the special Line Vac to operate when there was a power failure to protect the workers in the area.
For customers with space limitations, smaller sizes can be created while still offering the same quality of conveyance. In situations where the Line Vac requires a specific flange mounting option, EXAIR can accommodate. Applications requiring custom mounting holes, brackets or inlet positions are no problem to solve due to EXAIR’s in house manufacturing. For applications where stock aluminum, or 303 and 316 stainless steel won’t work, alternate materials like PVDF, OVC or PTFE can be utilized. Even in extreme environments, EXAIR can produce both heavy duty or high temperature iterations to handle even the toughest material or conditions. Other details like the customer’s particular hose size, or pipe threading are specifications that EXAIR will have no problem accommodating.
Stock Line Vac models include standard, Heavy Duty, high temperature, Light Duty and Sanitary Flange. All versions are able to be customized with different connections to meet customer’s specific needs. All Line Vacs are CE compliant and OSHA safe.
