摘要： An exhaust fan for bathrooms and the like having two principal structural elements--a housing assembly and a motor plate assembly--wherein the housing assembly includes a generally cylindrical housing formed of injection molded plastic. The housing assembly includes a circumferential mounting flange and mounting clips carried thereon for mounting the fan in a ceiling panel or the like in an arbitrary angular orientation. Flexible mounting tabs on the motor plate assembly releasably engage notches on the housing for snap together assembly. Integral strain relief for power supply wiring is molded into a wiring compartment in the housing. An oval duct connector having an outer circumferential lip extends from an exhaust outlet and is adapted to releasably engage a round flexibly resilient spring reinforced duct thereover. The motor plate assembly also covers the wiring compartment when fitted into the housing assembly.
