EXAIR has a Line Vac for your Application!

With countless number of different Models to fit every application, EXAIR Line Vacs are used to convey everything from the lightest of packing peanuts to heavy steel shot.  They’re versatile, reliable, durable, and incredibly easy to install and operate. 

Line Vacs are EXAIR’s current promotion too, see the offer here.

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 dense, heavy and abrasive material and pieces.  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. They are exceptionally simple to install and solve many “bucket and ladder”, loading and scrap removal applications. 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 manufactured 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.

Heavy Duty Line Vac: Hardened Alloy Construction and High Performance

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 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.

EXAIR’s Light Duty Line Vac

On the other end of the Line-Vac spectrum, EXAIR also manufactures 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.

Model 161200-316 – 316 Stainless Steel Sanitary Flange Line Vac

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.

We are also able to make custom Line Vacs to mean any application, see an example of some unique to the application Line Vacs here, https://blog.exair.com/2020/07/01/custom-products-for-custom-applications/

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 have any questions on how our Line Vacs can help save you money give us a call! One of our application engineers will be happy to assist!

Why Is Ambient Air Entrainment Needed For Pneumatic Conveyance?

When attempting to convey material pneumatically it can sometimes not work as one may hope. This could be due to the lack of ambient air entrainment to generate the vacuum flow which lifts the material away and moves the material. The video above gives a brief example of this.

If you would like to discuss pneumatic conveying products or processes, please contact us. EXAIR’s Line Vac air operated conveyors are a great solution for manual “bucket and ladder” applications, hopper loading, scrap conveyance, media recovery and more!

What’s So Great About Threaded Line Vac Pneumatic Conveyors?

Conveyor systems come in many shapes, sizes, and configurations. They can be run at different speeds, and are made of various materials, depending what they’re carrying, and why they’re carrying it. And sometimes, they’re hilarious:

If you’re looking to move solids, in bulk, through pipe, there’s not a simpler way to do it than with an EXAIR Threaded Line Vac.  Like our ‘standard’ Line Vacs, they use compressed air to generate a powerful vacuum flow to get air behind the pieces and carry them along:

Instant conveyor – just add compressed air.

But, while the ‘standard’ Line Vacs are made for use with Conveyance Hose, the Threaded Line Vacs have male NPT threads so you can pipe them in line.  We have a range of options, depending on the nature of your applications:

  • Sizes: 3/8 NPT to 3 NPT.
  • Materials: aluminum, 303SS, 316SS, and hardened alloy.
  • Performance: aluminum, 303SS and 316SS Threaded Line Vacs are made for standard duty; the hardened alloy Heavy Duty Threaded Line Vacs offer higher vacuum performance as well as superior abrasion resistance.
  • Environment: the materials of construction listed above may be important because of the nature of the product being conveyed, but they also have different temperature ratings.  Our Stainless Steel Line Vacs also come in a High Temperature design, in case the material – or the environment – is particularly hot:
    • Aluminum: 275°F (135°C)
    • Heavy Duty Hardened Alloy: 400°F (204°C)
    • 303 or 316SS: 400°F (204°C)
    • High Temp 303 or 316SS: 900°F (482°C)

If you’ve got a conveyor application you’d like to discuss, give me a call.

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.

line vac family
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.
