Exair’s new 3 NPT (national pipe taper) Heavy Duty Threaded Line Vac is an in-line conveyor that transports high volumes of material through ordinary pipe. According to Exair, the threaded line vac is designed for rugged, industrial applications; they are made of a hardened alloy to prevent premature wear when transporting abrasive or heavy materials like garnet, glass, sand, shot blast, tumbling media or metal fittings. They feature large throat diameters that convey more material – typically twice that of ordinary air powered conveyors – over long vertical and horizontal lengths.
The Heavy Duty Threaded Line Vac conveyors reportedly eject a small amount of compressed air through directed nozzles to produce a vacuum on one end and high output flows on the other with instantaneous response. Conveyance rate can be fine-tuned to suit the needs of the user’s application via a pressure regulator. Exair says there are no moving parts to wear out and no electricity is required.
Seven sizes from 3/4 NPT to 3 NPT fit standard pipe and coupling sizes. Additional models made from aluminum, 303SS and 316SS are also available in 11 sizes, with or without threads. Sanitary flange models from 1-1/2" to 3" are also available.
