"A Fan Assembly"
Abstract: A fan assembly for creating an air current comprises an air inlet (20), an air outlet (14), an impeller (64) and a motor (68) for rotating the impeller to create an air flow passing from the air inlet to the air outlet. The air outlet (14) comprises an interior passage (94) for receiving the air flow and a mouth (26) for emitting the air flow. The air outlet defines an opening (24) through which air from outside the fan assembly is drawn by the air flow emitted from the mouth. The motor (68) has a rotor which, in use, is capable of rotating at a speed of at least 5,000 rpm.
