Air Operated Conveyors for Dense and Abrasive Materials

Heavy Duty Line Vac 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 type of 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 your 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, 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 Vacs™.

The 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.  We 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, the Heavy Duty Line Vacs.

Heavy Duty Line Vac Kit

The Heavy Duty Line Vacs are engineered to move abrasive materials with increased conveyance rate.  They range from ¾” O.D. standpipes as our smallest up to 3” O.D. standpipes for hose connections.  The construction is made from a hardened alloy to resist wear from abrasive bulk products like steel parts, sand, glass, ceramic, etc.  The Heavy Duty Line Vac can create a high vacuum level to pick up heavier objects as well as conveying larger volume of material.  If 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 has no moving parts and is a great product to use in rugged industrial applications.  You will not have to worry about any motors or bearing 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 ergonomically help in saving the backs and knees of your operators.  For our U.S. and Canadian customers, we are running a promotional ad.  You will receive a 2” Flat Super Air Nozzle, a $72.00 value, for free from now until the end of October 2020 with a qualified purchase online.  If you would like to discuss your conveying application further, please contact an Application Engineer at EXAIR.  We may have a solution for you.
