Custom Solutions For Conveying Dry Material

The ideal solution for conveying large volumes of material over long distances.

EXAIR’s Line Vac compressed air operated conveyors have no moving parts or motors to wear out, providing a maintenance free way to move dry material from one location to another. We offer several different types and sizes of Line Vacs like our Standard Line Vacs, available from 3/8″ up to 5″  or our Threaded Line Vacs, with NPT threaded connections up to 3″. The Heavy Duty Line Vac are constructed of Hardened Alloy for superior abrasion resistance, available in sizes from 3/4” to 3”, smooth and threaded connections or the Light Duty Line Vac commonly used for smaller volume, shorter distance processes, with sizes from 3/4″ to 6”. We even offer Sanitary Flange Line Vacs from 1-1/2″ up to 3″ for processes requiring frequent cleaning. All of these products are in stock, ready to ship from our factory here in Cincinnati, Ohio.

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:

Flanged design, easy to install


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.

 

 

 

Chemical resistant construction for washdown areas

 

 

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.

 

 

 

Custom funnel design for small, granulated material like sugar or salt

 

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.

 

 

 

 

 

Miniature size for confined workspaces

 

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!

Maintenance Free And Proud Of It

Caller: Do you sell rebuild kits?
Me: Yes, but…why?

This is a WAY oversimplified summary of the start of a popular conversation that an EXAIR Application Engineer might have with a caller looking to restore a particular product to proper operation. Truth is, most of our products have no moving parts, and if you supply them with clean, dry air, they’ll run maintenance free, darn near indefinitely. We’ve documented this in specific cases regarding a Reversible Drum Vac from 1999, a Vortex Tube from 1987, and a Cold Gun from 1985.

Product & year of manufacture, from top left: Reversible Drum Vac (1999,) Cold Gun (1985,) Vortex Tube (1987.) All still performing within factory specifications.

Caller: So…DO you sell rebuild kits?
Me: Yes, but…only when necessary.

It’s important to note that none of the products mentioned above needed any parts replaced to return to service. Sometimes, a good cleaning is all that’s required. We can help you with a video tutorial if you want to know how to restore a Reversible Drum Vac, an Air Knife, or an Atomizing Spray Nozzle, for instance.  And we’re making new videos all the time for product maintenance, operation, tips & tricks, etc.

Caller (again): So…you DO sell rebuild kits?
Me: Yes, of course!  I mean, who wouldn’t sell rebuild kits for their products?

Take our Safety Air Guns, for example. We offer Service Kits, if the trigger and/or internal valve of a Soft Grip or Heavy Duty Safety Air Gun starts to wear or leak, it’s super easy to replace. We’ve also got replacement springs for the “fail shut” feature of the ball valve of a Super Blast Safety Air Gun. Just about anything else that could be wrong with a Safety Air Gun’s performance can be addressed by cleaning the nozzle.

We also recently added Rebuild Kits for our Atomizing Spray Nozzles to inventory. These contain all of the seals (and moving parts, for the No-Drip models) to restore an EXAIR Spray Nozzle to rated performance.

Keep your EXAIR Atomizing Spray Nozzle (left) in perfect working order with a simple & inexpensive Rebuilt Kit (right of the nozzle.) Contact an Application Engineer to select the one for your product.

For other products, we can also provide replacement gaskets & seals for the Reversible Drum Vac & Chip Trapper products, O-rings for the Line Vacs, Chip Vacs, and Heavy Duty Dry Vacs, new elements for Filter Separators & Oil Removal Filters…just to name a few.

Bottom line: if your EXAIR product isn’t performing the way it used to, give me a call.  It will be my pleasure to help you get it working like new, so that you can continue to get the most out of it.

Video Blog: Adjusting a Vortex Tube

See how simple it is adjust the outlet temperature of an EXAIR Vortex Tube below zero degrees Fahrenheit.  Vortex Tubes  are a low cost, reliable maintenance free solution for many industrial spot cooling applications.

EXAIR Vortex Tubes are constructed of stainless steel to resist corrosion and oxidation for years of reliable, maintenance free operation. They are used to provide cooling for electronic controls, dry machining operations, cameras, sensors, CCTV, hot melt adhesives, soldering, brazing, gas sampling, heat seals, and environmental chambers.

There are many advantages when using Vortex tubes:

  • No moving parts
  • No electricity
  • No chemicals
  • Low cost
  • Maintenance free
  • Instant cold air
  • Easily adjusted for temperature
