Abstract
A heating, ventilation, and/or air conditioning (HVAC) blower assembly includes a motor and a fan wheel, wherein the motor drives rotation of the fan wheel about an axis of rotation. A blower housing accommodates the fan wheel within a hollow portion and is defined by a base, a curved boundary, a front boundary, and a rear boundary. An inlet port extending through the front boundary facilitates intake of airflow into the fan wheel. An outlet port extending through the base facilitates expulsion of the airflow from the fan wheel. A first portion of the curved boundary includes an involute profile and a second portion of the curved boundary includes a footing extending from the first portion to the base such that airflow exiting through the outlet port is guided away from the fan wheel by an interior-facing surface of the footing.
