1.-6. Ventilating fan

Abstract

The design relates to a filter fan for electrical enclosures; the characteristic features include a cover having a square border with rounded corners, incorporating a front grille composed of a plurality of essentially horizontal louvers angled downward toward the front side of the filter fan; the louvers extend laterally to the side border of the cover; a logo element may be clipped onto the louvers for branding purposes; a fan is mounted at the rear of the housing, and a variant of the design is provided without the fan (exhaust filter).
