Abstract: The disclosure relates to a blower assembly having a blower housing, an impeller adapted for rotation about an axis A-A disposed in blower housing, and an intake plenum cooperating with the interior first surface of the blower housing to define an air entrance passage for receiving an incoming air flow. The intake plenum includes means to split the incoming air flow into a plurality of air streams and direct the air streams to predetermined portions of the impeller susceptible to stall conditions as the impeller rotates about the axis A-A. The means to split the incoming air may include a splitter plate disposed in the air entrance passage or at least one port defined in a portion of the air intake plenum adjacent the impeller.
