double deflection grilles

Most desirable for supply air in side-wall locations. With aerofoil shape louvers in both horizontal and vertical direction, minor air motion problems can be quickly corrected by adjusting the vanes. An opposed blade damper installed behind the grille is used for adjusting air volumes during air balancing. Choice of horizontal louvers in front and vertical at the back or vice versa available.
