Abstract

A fan housing having a peripheral wall disposed about the fan's axis of rotation. A plurality of flanges including reinforced hems are integrally formed with and extend perpendicularly of the peripheral wall toward the fan's axis of rotation. A screen fabricated from interconnected, perpendicular wire strands is coupled to the flanges by means of the reinforced hems with rigid but malleable tabs integrally formed thereon that are bent around a peripheral strand of the screen. Apertures are defined by and extend through the peripheral wall and the flanges to provide access to the tabs such that the tabs may be urged toward the flanges to secure the screen in position. The same apertures provide access to the tabs such that the tabs may be urged away from the flanges to disengage the peripheral strand from the tabs such that the screen may be removed and replaced.
