EXAIR's compressed air operated Line Vac connects to standard hose to create a powerful in-line conveyor material handling system. Unlike belt or screw type conveyor equipment, Line Vac conveyors are ideal for moving large volumes of material over long distances without clogging or jamming. The material flow rate is easily controlled with a pressure regulator. An optional bracket permits easy mounting. No moving parts or electricity assures maintenance free operation. Sizes will fit from 3/8" to 5" inside diameter hose. Available in aluminum, type 303 stainless steel or type 316 stainless steel.EXAIR's compressed air operated Line Vac connects to standard hose to create a powerful in-line conveyor material handling system.
