Abstract

A dual-sided impeller for a centrifugal blower assembly is provided. The dual-sided impeller comprises a plurality of fan ribs defined in a single continuous metal sheet and extending from a hub toward a circumference of the impeller. Each of the plurality of fan ribs has first and second vanes, wherein the first and second vanes extend in opposing directions relative to a plate region of the impeller. The first and second vanes can comprise one or more of a forward-curved vane, a backward-curved vane, a forward-inclined vane, a backward-inclined vane, and a radial vane. The centrifugal blower assembly comprises a blower housing, wherein the dual-sided impeller is disposed within the blower housing.
