Air Operated Conveyors for a Multitude of Jobs

With 119 distinct Models, EXAIR Line Vacs are used to convey everything from down feather to steel shot.  They’re versatile, reliable, durable, and incredibly easy to install and operate. Most applications can be completed using one of our many stock Line Vacs. Additional applications include part transfer, waste or trim removal, hopper loading, filling operations, chip removal and fiber tensioning.

Lightweight and durable aluminum is the most popular choice, but we make them in stainless steel (Types 303 and 316) for heat and corrosion resistance. For extreme heat, the High Temperature option affords protection to 900F (482C) in either 303SS or 316SS.

They are available from 3/8″ to 5″ diameters, for use with hose, tube or pipe. Line VAcs have smooth ends for hose or tube. The threaded models use NPT threads from 3/8 NPT to 3 NPT to turn ordinary pipe into an air conveyor! They can also be bought with sanitary flange ends for easy disassembly when necessary for cleaning or maintenance.

Materials include aluminum, Type 303 and Type 316 stainless steel or a hardened steel alloy for moving abrasive materials like garnet, glass, or blasting media.

With that being said, there are always applications that need a special product. And because of that we do make “special” or custom products when the need arises.

Special PVDF Line Vac

For example this Live Vac has the sanitary flange design, but the customer needed it made from a special material so their product passing through it wouldn’t be contaminated by metal. So we did just that, we designed built and shipped this line vac and it worked amazingly well!

Accessories include the transport hose, mounting brackets, filter and regulators.  A filtering drum cover is very useful to keep material and/or dust inside, when transporting materials into a drum.

No matter what kind of bulk material you need to move, or what type of special conditions you have. EXAIR has a Line Vac product for it.  If you’d like to find out more, give me a call.

Turn Ordinary Pipe into a Powerful Conveyor w/ EXAIR’s Threaded Line Vac

threaded line vacs

EXAIR’s Line Vacs are the ideal low-cost solution for bulk material transfer. 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 an 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 proprietary hardened alloy steel for use in abrasive applications. Where most materials would wear out over time, the Heavy Duty Line Vac is the ideal solution for heavy and abrasive materials. In addition to being abrasive resistant, it’s 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 3:00 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 Line Vac Replaces Yet Another Injury-Prone Bucket & Ladder Operation

I recently had the pleasure of talking with a caller from a consulting firm that specializes in improved ergonomics.  They work with clients on everything from preventing carpal tunnel syndrome through the use of things like gel-filled mouse pads for office personnel, to preventing injuries in the workplace due to repetitive strain, heavy lifting, and other physically demanding tasks.  They called about an operation where workers used buckets to move 150 pounds of dense pellets from a large container into a smaller vessel for weight load testing.  After the test, they move the pellets back into the container, where they stay until the next test is to be run.  Then they do it again.

This, of course, was a great fit for a 2″ Heavy Duty Line Vac and a 10ft length of Conveyance Hose. They simply move the suction & discharge hoses from, and to, the storage container & test vessel.  Risk of injury is greatly reduced, as the whole Line Vac conveyance system is less than half the weight of one bucket of the material.

Line Vac + Hose + Compressed air supply = complete conveyance system solution.

This is just the latest success story in the long history of EXAIR Air Operated Conveyors.  They’re on the shelf in a range of sizes and materials of construction to meet most any need.  If you don’t see what you’re looking for, though, call me and we can discuss your needs.

Heavy Duty Air Conveyors Resist Abrasion, Transfer Heavy Materials

Threaded Heavy Duty Family

As an Application Engineer, I get the pleasure to speak to many companies about trying to find a simple, long-lasting, powerful but quiet transfer systems.  They have operators that climb steps to dump bags of material in hoppers above.  Or they need a compact way to remove scrap from their process.  Or they have budgetary constraints to convey material from point A to point B.

If your company had to tackle any of these issues, EXAIR can help you.  We manufacture Air Operated Conveyors that do not have any moving parts, are very compact in design, and have a high throughput capacity.  They can attach easily to standard hoses, pipes, or sanitary flanges.   These inexpensive conveyors are designed to make conveyance safer and ergonomically better for your operators.  EXAIR calls this product line, Line Vac™.

Line Vacs use a small amount of compressed air to generate a vacuum by a Venturi effect.  The unique design generates a high velocity to create a powerful vacuum on one side.  Once the product reaches the throat area of the Line Vac, the compressed air will carry the product the rest of the way.  The product can reach horizontal distances up to 100 feet (30 meters) and vertical heights up to 20 feet (6 meters).  EXAIR manufactures a variety of Line Vacs in different sizes, styles, and materials.  In this blog, I will cover our most powerful and abrasion resistant type, Threaded Heavy Duty Line Vac.

Male NPT Threads make permanent and rigid installation into a piping system a breeze.

Threaded Heavy Duty Line Vacs are designed to convert regular piping into a powerful conveying system.  They range from ¾” NPT to 3” NPT and can connect easily to PVC and steel pipe fittings.  The construction is made from a hardened alloy steel to resist wear from abrasive bulk products like steel parts, sand, glass, ceramic, etc.  The Threaded Heavy Duty Line Vac can create a higher vacuum level to pick up heavier objects as well as conveying larger volume of material.

When purchased as a kit, the Line Vac will come with a filter, regulator, and a mounting bracket.  This adds overall value in mounting, controlling, and protecting the Line Vac for years to come.  This simple device is a great product to use in rugged industrial applications, and with no moving parts, you will not have to worry about any motors or bearings prematurely wearing out.

If you need to convey heavy materials like steel shot or abrasive products, the Heavy Duty Line Vac could be a blessing for you.  Not only can they transfer material safely and quickly, but they also will help ergonomically in saving the backs and knees of your operators.  If you would like to discuss your conveying application further, please contact an Application Engineer at EXAIR.  We may have a solution for you.

EXAIR Line Vacs: Dozens Of Models; Endless Applications

With 119 distinct Models, EXAIR Line Vacs are used to convey everything from down feather to steel shot.  They’re versatile, reliable, durable, and incredibly easy to install and operate.  Consider this list of uses, starting with our smallest Line Vac, and going to our largest:

  • Model 6058 3/8″ Stainless Steel Line Vacs pull mica from a bulk container and spray it into a mold for making decorative stones, to apply a glittery surface.  They used to do it by hand, but the Line Vacs spread it more consistently.
  • A Model 6079 1/2″ Aluminum Line Vac pulls small metal scraps from a metal trimming operation, as they’re cut, keeping the work area clean.
  • Model 130075 3/4″ Light Duty Line Vacs perform a similar function in a plastic cutting machine, conveying away cut chips and eliminating the need for periodically stopping the machine to clean up.
  • A medical device manufacturer saw a 50% increase in productivity when they went from removing flash by hand from molded silicon parts to using a Model 6061 1″ Stainless Steel Line Vac to suction it away automatically.
  • A mining equipment manufacturer reclaims sand from a secondary operation on their green sand molds with a Model 6062 1-1/4″ Stainless Steel Line Vac.  This keeps their mold area clean, and has eliminated waste in production.
  • Model 140125 1-1/4 MNPT Aluminum Threaded Line Vacs eliminated a  “bucket and ladder” operation where cotton seeds needed to be loaded into 7-foot high hoppers.
  • Model 151150 1-1/2 MNPT Heavy Duty Threaded Line Vacs, fitted into black iron pipe systems, reclaim hot metal chips from a deep channel milling machine, automating the transfer to the recycling hopper.  This eliminated the risk of lifting AND burn injuries from the manual handling of the hot chips.
  • Model 6084 2″ Aluminum Line Vacs vacuum trim scrap from custom label making machines to a central scrap bin, keeping the floor clean, and keeping operators from having to empty individual bins at each machine.
  • A Model 6065 2-1/2″ Stainless Steel Line Vac conveys rejected peanuts (identified and segregated by a vision sorting machine) from the catch pan to a large collection hopper.  This is hauled away at the end of each shift, instead of an operator paying constant attention to the catch pan.
  • Model 161300-316 3″ Sanitary Flange Line Vacs replaced mechanical conveyors in a grain mill, incorporating a totally enclosed Clean In Place (CIP) system.  This greatly reduced contamination controls when the product was openly conveyed, and actually increased their conveyance rates of their bulk grains.
  • A Model 6087 4″ Aluminum Line Vac conveys an additive (in pellet form) into an asphalt mixer, replacing an auger conveyor that left product in the hopper and would clog regularly, resulting in messy spills.
  • A company that recycles spent ammo from gun ranges uses a Model 6088 5″ Aluminum Line Vac to convey the granulated rubber backstop material into their truck.  After the ammo is separated, they use the Line Vac to replenish the granulated rubber into the backstop.
  • A Model 130600 6″ Light Duty Line Vac conveys linen squares (mostly 12″ and 24″ square) through the main header of a sorting operation in a commercial laundry facility.  The system also incorporates several Model 120024 4″ Super Air Amplifiers in individual “pickup” branches.
The EXAIR Line Vac is a fast, low cost way to convey most any bulk material.

No matter what kind of bulk material you need to move, EXAIR has a Line Vac product for it.  If you’d like to find out more, give me a call.
