Abstract
A centrifugal blower assembly includes a housing and a blower wheel coupled to the housing. The blower wheel includes a plurality of blades circumferentially-spaced about an axis of rotation. Each blade includes a length and is oriented at a first angle along the length with respect to the rotational axis. The centrifugal blower assembly also includes a plurality of circumferentially-spaced fins coupled in flow communication with said blower wheel, said plurality of fins configured to direct an inlet airflow into the blower wheel such that a relative velocity direction of the inlet airflow is oriented at the first angle with respect to the rotational axis.
