A blower housing. The blower housing comprises an axis about which the blower housing is oriented; an inlet allowing the entrance of fluid in an axial direction for the blower housing; a discharge for the blower housing discharging fluid in a radial direction; a cutoff for the blower housing extending in the axial direction and located in the vicinity of the outlet; and a fluid flow path extending from the cutoff to the outlet. The fluid flow path is open in a radial inward direction to the axis to receive fluid from the inlet. The fluid flow path has a progressively increasing cross-sectional area, and the fluid flow path alternately expands in the radial and axial directions. |
