Abstract

601755 Disclosed is a fan assembly where the inlet grille blades are curved and angled so that air, when drawn into the casing, is caused to effectively rotate about the central axis of the casing and this moving column of air is drawn through the fan and strikes the fan blades at an optimal angle to permit effective delivery of the air through the casing and noise reduction. The fan assembly includes a casing which has a cylindrical portion and an open end. The fan assembly further includes a grille extending over the open end and having an annular peripheral portion lying in a grille plane; and a plurality of curved blades extending from a central portion of the grille to the annular peripheral portion. The curved blades at a minimum angle effectively normal to the grille plane at the central portion and a maximum angle to the normal plane at the annular peripheral portion, the maximum angle being less than 40°; and in the casing a fan motor and fan blades mounted whereby air can be drawn into the casing through the grille, the grille causing the air drawn in to rotate the air about a central axis of the casing and to strike the fan blades at an angle.
