ABSTRACT:
A centrifugal blower assembly is provided which includes an improved blower housing construction wherein a pair of end panels each define a plurality of apertures disposed along a line corresponding to the profile of a blower spiral. An elongated scroll member includes a plurality of tab members spaced along each longitudinal side and extending through the apertures in the pair of end panels for conforming the scroll member to the blower spiral profile. At least a portion of the plurality of tab members are deformed relative to the apertures to maintain a connection between the scroll member and the end panels to form the blower housing. The assembly also provides isolated drive motor and air intake compartments, combined motor mount and support means for blower housing, and access for removing the drive motor from its compartment without removal of any side walls.
