Abstract

In one aspect, a centrifugal blower assembly is provided. The centrifugal blower assembly includes a housing defining an interior space and an impeller configured to channel an airflow within the interior space. A motor is coupled to the impeller and configured to rotate the impeller about an axis. The centrifugal blower also includes a plurality of mounting arms. Each mounting arm of the plurality of mounting arms includes a first end coupled to the housing and a second end coupled to the motor. Each mounting arm of the plurality of mounting arms has a cross-sectional profile that comprises a portion of an airfoil shape.
