Envirco 3/4" Double Deflection Supply Grille

Introduction The double deflection supply grille provides effective directional control of the air stream in one, two, three, or four directions. Each bank of bars is pivoted at the front which gives a uniform appearance regardless of blade angle setting. The hallow air-foil grille bars are spaced on 3/4" centers. Each bar is adjusted for the desired air deflection without affecting the setting of any other bar. The DDSG is available with horizontal face bars (DDSG-H) or vertical face bars (DDSG-V). It is also 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.
