Abstract

A molded plastic air diffusing screen in an air supply system provided for effectively diffusing or deflecting air supplied through a coreless or vane-free duct such that undesirable air turbulence and draft/currents are substantially diminished; more particularly, the novel plastic screen diffuser minimizes noise emanating from the penetrating air supply.
