A roots blower pump is a positive displacement rotary lobe pump that operates by pumping a fluid with a pair of meshing lobes, not unlike a set of stretched gears. Fluid is then trapped in pockets surrounding the lobes and carried from the intake side to the exhaust.


A motor blower package is the ‘air mover’ in a pneumatic conveying system. In a pressure system, atmospheric air is filtered before entering the system, then that air is powerfully blown through pipes. In negative pressure systems, the air is filtered from the system side and exhausts to the atmosphere.


We stock a wide variety of consumables including lubricants, inlet valves, gauges, filter elements, connectors, and much more.

Blower Oils

To decrease the noise coming from blower packages, sound enclosures are used. Any mechanical noise coming from the blower, motor, mechanical coupling, etc. are eliminated by these acoustic enclosures.
