Abstract
A fan assembly includes a casing, which is substantially cylindrical in shape with a fan motor and fan blades located therein, so that air can be drawn into the casing and delivered therefrom. A grille extends over an open end of the casing and has a plurality of angular curved blades extending from a central portion thereof to the periphery. These curved blades are, preferably, at an angle to the normal plane through the grille, so that air in the casing is caused to move to the fan blades at an angle permitting efficient operation of the fan.
