Abstract: A blower for use in a climate controlled system includes an outer housing, a plurality of protruding members extending from the outer housing, an inlet opening in the outer housing, an impeller positioned with an internal cavity or space defined by the outer housing and a filter configured for placement against at least some of the protruding members. In some embodiments, the space created by the protruding members between the filter and outer housing facilitates the transfer of air or other fluids into the internal cavity of the blower.
