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!

Stainless Steel Adjustable Air Amplifiers Replace Blower in Exhaust Hood Application

Vent hood
EXAIR Stainless Steel Adjustable Air Amplifiers model 6034

 

I was working with our Indonesian distributor the other day on an interesting application in the sugar refining industry.

The application was in a sugar refining plant. As the sugar cane is cooked down, the resulting gas vapor is pulled up through a vent hood and exhausted outside the building. The customer was using a 16” diameter blower to create the needed draft to draw the vapors. The problem is that the vapors are corrosive and sticky when cold. The effect is that the blower blade becomes caked with deposits which, in turn corrode the blade and it must either be cleaned and/or replaced at frequent and regular intervals.

The customer wanted to get away from having to deal with the blower issue if they can, so they turned to our distributor for ideas on how to solve the problem using EXAIR equipment. Turns out that a cluster of (3) model 6034 4” Adjustable Air Amplifiers operating at 5 BARG input pressure are able to generate the necessary flow to replace the blower in this system.

The keys to success in the application were the fact that the Adjustable Air Amplifiers are constructed of Stainless Steel to resist the corrosive effects of the gas vapor. Also, there isn’t any deposits on the blade that need to be dealt with. While cleaning of the Air Amplifiers is recommended in this application, the maintenance interval was able to be much longer between cleanings.

In many industrial applications, blower driven or electric motor driven equipment is usually preferred in an effort to save energy. This was a good example of a case where the quality of having no moving parts was able to offset other maintenance costs that made use of a blower actually more expensive for the user.
