ABSTRACT:
A rotating fan assembly is provided for use in single stage and multi-stage applications. The fan assembly includes a fan member having a tapered disk member, a flat annular ring member and a plurality of blade members interposed between the disk and the ring. The fan member may be housed in an enclosure shroud having a tapered case and a flat shell member thereby reducing case length from start of the shell to the inlet plane. The flat shell member doubles as a shroud for both the rotating fan member and for a stationary fan when used in multi-stage designs.
