EXAIR’s Heavy Duty Air Powered Conveyors

EXAIR's Heavy Duty Line Vac is a compact and quiet powerful in-line conveyor that transports high volumes of material through ordinary hose or tube. Commonly used to transfer complex shapes, bulk solids and waste, the units feature large throat diameters that make it possible to convey more material over long vertical and horizontal lengths. The conveying rate of this heavy duty conveyor is typically twice that of ordinary air powered conveyors.

Commonly used to transfer complex shapes, bulk solids and waste, the units feature large throat diameters that make it possible to convey more material over long vertical and horizontal lengths. The conveying rate of this heavy duty conveyor is typically twice that of ordinary air powered conveyors.

Heavy Duty Line Vac ejects a small amount of compressed air through directed nozzles into the throat to produce a vacuum on one end and high output flows on the other. Response is instantaneous. The material conveying rate is easily controlled with a pressure regulator. An optional bracket permits easy mounting. No moving parts or electricity assures maintenance free operation.
Designed for rugged, industrial applications, Heavy Duty Line Vac has a hardened alloy construction that helps prevent premature wear. Seven sizes up to 3″ (76mm) are available that fit popular hose and tube diameters. Applications include part transfer, hopper loading, material conveying, waste/trim removal, fiber tensioning, chip removal and filling operations. https://exair.co/184-hdlvdir

T.J. Davies' Retention Knobs

Our retention knobs are manufactured above international standards or to machine builder specifications. Retention knobs are manufactured utilizing AMS-6274/AISI-8620 alloy steel drawn in the United States. Threads are single-pointed on our lathes while manufacturing all other retention knob features to ensure high concentricity. Our process ensures that our threads are balanced (lead in/lead out at 180 degrees.) Each retention knob is carburized (hardened) to 58-62HRC, and case depth is .020-.030. Core hardness 40HRC. Each retention knob is coated utilizing a hot black oxide coating to military specifications. Our retention knobs are 100% covered in black oxide to prevent rust. All retention knob surfaces (not just mating surfaces) have a precision finish of 32 RMA micro or better: ISO grade 6N. Each retention knob is magnetic particle tested and tested at 2.5 times the pulling force of the drawbar. Certifications are maintained for each step in the manufacturing process for traceability.
