Abstract

A ventilation fan comprising a cylindrical tubular housing 126 with an axially orientated inlet and outlet, a centrifugal impeller is within the housing with its axis of rotation parallel to the axis housing. A motor is provided for driving the impeller 114 and a baffle 122 directs air flow from the inlet towards a central region of the centrifugal impeller. Preferably the fan unit includes a guard formed of looped cross members and circumferential bars on which the motor is adjustably mounted. Preferably the baffle includes an angled or curved surface.
