Regenerative Blowers
Regenerative blowers are configured to generate pressures or vacuums equal to those of larger multi-stage or positive displacement blowers. They are equipped with inlet and outlet ports oriented in the same direction from the impeller blades. Creating a centrifugal action, the impellers suck in air then accelerate it and push it out, therefore offering vacuum and compression. The air is accelerated within the blower unit through regenerative action as it rebounds off the annular housing and toward the base of the blades, ending up being hurled through the out port. There is a stripper section at the outlet where the ring-shaped housing becomes more tightly fit to the impeller blades, acting as a funnel to "strip" the air from the blades and divert it out.
Manufacturers offer regenerative air blowers of various rugged constructions for industrial vacuum and compression applications, even in chemical processing and specialty gas environments. Manufacturers can accommodate variable flows and spatial needs, offering compact dimensions, lightweight construction and instrument grades. Whether your concern is noise reduction or contamination prevention, quiet office specifications and hermetically sealed "glovebox" models are available. Utilizing DC motors, AC single-phase motors, AC three-phase motors or engine power in their products, manufacturers offer compression regenerative blower systems for compressors and air supply units and vacuum regenerative blowers for vacuum pumps or exhausters that remove air, fumes or gases through suction. Regenerative blower features include control panels and pressure or vacuum gauges.
