Heavy Duty Line Vacs: Made for Abrasive Materials and/or Higher Throughput

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 table below gives a quick comparison of the EXAIR Light Duty Line VacStandard Line Vac & the Heavy Duty Line Vac models.  The test shows the 2″ size in each model conveying Rock Salt over two different horizontal distances.  As expected the Heavy Duty Line Vac conveys more material in less time!

Heavy Duty Line Vac Distance

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.

HD Line Vac Performance

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.

The Blog of all Blogs: A Quick Resource of Blogs that we Blogged

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.

Turn Ordinary Pipe Into A Powerful Transfer System w/ EXAIR’s Threaded Line Vac!

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.

What’s So Great About the EXAIR Sanitary Flange Line Vacs?

The greatness of EXAIR Line Vac Air Operated Conveyors can be summed up in a simple math(like) formula:

Line Vac + Hose or Pipe + Compressed Air = Instant Conveyor System

Today, dear reader, we’re going to explore the factors that contribute to the particular greatness of our Sanitary Flange Line Vacs:

Common industrial piping connections are difficult to sanitize, and offer ample breeding ground for bacteria.

Clean In Place capability. Many industrial fluid piping installations are made up of threaded or soldered connections, like those shown in the photo to the right. These products are easy to work with, readily available, and relatively inexpensive. They’re also unacceptable in facilities that require frequent cleaning to eliminate contamination – biological and otherwise – from their products & processes. Equipment in pharmaceutical, food production, and dairy farm facilities must be able to be sanitized effectively, so they’ll all use pipe & fittings that comply with specifications set forth in ISO Standard 2852 (Stainless steel clamp pipe couplings for the food industry) specifications for dimensions, surface roughness, materials, and assembly & hygienic requirements. While they’re known by a number of names – Tri-Clamp, Tri-Clover, S-Clamp, Sanitary, 3A, among others – they’re all aimed at compliance with ISO 2852. And EXAIR Sanitary Flange Line Vac products are compatible with any of them.

Sanitary Fittings come in number of configurations for quick & easy “making & breaking” for cleaning.

Diverse range of applications. While food & pharma are, by far, the main users, the ease of connection (and disconnection & reconnection), smooth ID specification for pipe, durability of stainless steel construction, and elimination of seams in fittings are all advantageous for other users as well:

  • A chemical company needed to remove long strands of cotton fiber away from a process, and convey it over a 60ft run to a scrap bin. The smooth ID of sanitary-grade stainless steel piping allows them to use a Model 161150-316 1-1/2″ Sanitary Flange Line Vac for reliable conveyance of this material, with no hang-ups or clogging in the long run of pipe.
  • An ammo manufacturer uses our Model 161200-316 2″ Sanitary Flange Line Vacs to convey small shell casings, in bulk from where they’re pressed, to where they’re loaded. They, too, like the smooth, seam-free pipe for conveyance, and the durability of all stainless steel construction. Another benefit is the quickness and ease of breaking & making the connections, as each Line Vac is used to convey these casings to multiple loading stations.
Sanitary Flange fittings make it easy to keep the inlet of this Model 161150-316 1-1/2″ Sanitary Flange Line Vac protected while not in use (left). The spring-loaded clamp makes it easy to swap out the cap for a barb fitting (middle) for use with a flexible suction hose (right).

Type 316 Stainless Steel Construction. Stainless Steel is specified for material construction for a number of reasons such as durability, aesthetics, and corrosion resistance. There are many alloys, and most will give you the smooth & shiny surface that folks think about when they think of stainless steel. Type 316, due to its hardness and particularly high resistance to chloride pitting corrosion, is extraordinarily popular in food & pharmaceutical application.

EXAIR Sanitary Flange Line Vacs come in four popular sizes, and are ideal for applications in the food and pharmaceutical industries…and others.

If you’ve got bulk material to move from “point A to point B”, EXAIR has a number of solutions to choose from. If you want to find out more, give me a call.
