When it comes to conveying bulk materials like pellets, grains, powders, etc., you’ve got plenty of choices: Mechanical conveyor types, like bucket, auger, and cleated belt conveyors can move product as far as you want, and as quickly as you want…they can be made as long as you want, and as big & fast as you want. “Fast” as in conveyance rate, that is. Lead time, including engineering, design, fabrication, and installation, can be months.
Air operated conveyors are quite popular too, and the dense phase models can move a lot of material a great distance, and quickly. Like the mechanical types, they have a wide range of economy to scale…and the price tags to prove it. Medium- and dilute-phase pneumatic conveyors are less complicated in design, which brings us to the heart of today’s blog.
EXAIR Air Operated Conveyors, or Line Vacs, are the simplest of all: the Line Vac itself used compressed air to generate a “pull/push” to draw material into the suction, and propel it through the discharge. We have a variety of models to choose from, but our focus today will be the Heavy Duty Line Vac.
EXAIR Heavy Duty Line Vacs are the workhorse of our Air Operated Conveyors product line. Consider their advantages:
*Made of a proprietary hardened alloy, they offer superior abrasion resistance & durability. They’re ideal for shot blast and tumbling media…the very stuff that’s MADE to wear metal surfaces down…and it’s no problem for the Heavy Duty Line Vac.
*Heavy Duty also means higher power, which means higher suction heads (up to 2-1/2 times increase) and conveyance rates (up to 11 times greater.) Oh, and that blasting shot & tumbling media I mentioned? Standard dilute-phase conveyors may have trouble moving that at all.
*Like our Standard Line Vacs, the Heavy Duty models’ Kits come with a Mounting Bracket for ease of installation, an Automatic Drain Filter Separator to keep the air clean & dry, and a Pressure Regulator so you can ‘dial in’ the performance you need.
*Also like our Standard Line Vacs, the Heavy Duty models use common sized conveyance hose (3/4″ to 3″ ID) and are also available with male NPT threads (3/4″ to 3″ as well) if you want to hard pipe them.
