ABSTRACT:
A regenerative blower having an impeller casing and an integral silencer casing separated from the impeller casing by a dividing wall. The impeller casing cooperates with a rotary impeller to define a generally annular fluid chamber having opposite end portions terminating at fluid inlet and outlet openings in the dividing wall opening into the silencer casing. Resilient compressible acoustic material contained within the silencer casing defines inlets and outlets fluid passageways respectively communicating with the inlet and outlet openings. A reversible flange plate forms a closure for the silencer casing. A first set of conduit fittings project from one side of the plate and a second of conduit fittings project from the opposite side of the plate and communicating with the first set through the plate. The first set of fittings is adapted for connection to threaded pipe. The fittings of the second set provide tubing or hose connections. The flange plate may be reversed relative to the silencer casing to expose a selected one of the sets of fittings externally of the silencer casing. The fittings of the other set are disposed within the silencer casing in pressing engagement with the resilient compressible acoustic material and establish communication with the inlet and outlet passageways defined by the acoustic material.
