Zusammenfassung:	An exhaust fan assembly is provided for expelling contaminated air from a building. The assembly includes fan housing connected to the building via a duct. The fan housing contains a fan the draws air from the building through the duct. An extensio n is mounted to the outlet end of the fan housing, and has a cylindrical upper end connected to a nozzle. A windband is connected to the upper end of the nozzle, and provides an air entrainment path that allows ambient air to mix with the exhaust air prior to exiting through an exhaust fan assembly outlet.
