Introduction
The 1/2” hinged filter return grilles have non-adjustable, hinged horizontal blades spaced on 1/2” centers. The grille core is secured to the face of the outer frame with stainless steel 1/4-turn fasteners, allowing quick removal for cleaning or changing the filters. The streamlined blades and opened spacing maintain a minimum effective free area of 50%, which minimizes intake velocity, reduces inlet pressure, and provides quiet operation.
The 50HFRG is available with or without an opposed blade damper (OBD). The OBD assures even distribution of air across the grille face as well as positive volume control.
