Abstract

An air blower includes an axial flow through assembly of motor and fan housing mounted in an axial flow through motor casing. The casing includes two sections formed of an injection molded, soft, resilient, elastomeric material which sections are basically cylindrical with closed ends at which are formed axially aligned flow through input and output air fittings. The inner end of each casing section is enlarged and the two abutted together to form a fan housing receiving chamber that tightly and elastically receives the fan housing. One end of the fan housing seats against the shoulder in the enlarged end of one casing section, and the other end of the fan housing seats against a plurality of positioning and reinforcing fingers integral with and spaced around the inner surface of the enlarged end of the other casing section. A number of circumferentially spaced, axially extending bolts pull the two casing sections together to tightly clamp the fan housing, and thereby the motor, to and within the enlarged housing receiving chamber of the casing sections.
