Abstract
A blower assembly for use with an HVAC module is provided. The blower assembly includes a scroll or volute shaped housing having an air inlet in a wall of the housing for receiving air to be blown by an impeller, and an air outlet from which the blown air passes from the housing. A blower wheel is secured to a rotatable motor-driven shaft extending along a central axis of the air inlet. At least one venture is provided adjacent to the air inlet of the housing, the at least one venturi connectable to an aspirator that is in fluid communication with a sensor unit. Wherein, during operation, the blower wheel pulls air both through the air inlet to the housing and through the at least one venturi.
