Composite air handling blower housing and method of assembly

摘要

An air handling blower housing for an HVAC system is formed by two opposed housing parts which are each fabricated of a compression molded reinforced thermoset polymer composition. The housing parts are joined along a parting line, preferably perpendicular to the axis of a motor driven impeller mounted within the housing by wedge shaped clips which engage cooperating bosses aligned with each other when the housing parts are joined. The construction of the housing parts provides for an improved method of assembly of an air handling blower of a type particularly adapted for HVAC systems.
