Abstract

A centrifugal blower for a furnace, heat pump, or other type of air handling unit includes a heat-generating blower housing that heats the airflow as the air passes through the blower housing. In some cases, the housing is made of a thermosetting resin impregnated with graphite or co-molded with a graphite cloth. Heat is generated within the housing wall by applying voltage across the housing.
