Critical Environment Installation Instructions
The 250 Series 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 hollow air-foil grille bars are spaced on .750″ centers. Each bar is adjusted for the desired air deflection without affecting the setting of any other bar.
Available with horizontal face bars (250-H) or vertical face bars (250-V).
Specify: Series S-44 Opposed Blade Damper attached to 250 Series to make supply registers. The SS-44 OBD assures even distribution of air across the grille face as well as positive volume control.
