Return air from office cabins is transferred into a general hall or an open office by a grille installed on the cabin door. Available with horizontal fixed louvers only and optional double frame to provide a finished look on both sides of the door.
Most desirable for supply air in side-wall locations. With aerofoil shape louvers in both horizontal and vertical directions, 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.
