Conveyors ease materials transfer

Exair has introduced Heavy Duty Threaded Line Vac conveyors that are
said to convert ordinary pipe into a powerful conveying system for bulk
materials including steel shot, metal parts, scrap and trim. Units
offer a hardened alloy construction, large throat diameters that make
it possible to convey more material over long vertical and horizontal
lengths, and the conveying rate is typically twice that of ordinary air
powered conveyors.
