The DR grille is a wall-mounted supply and extract air diffuser featuring individually adjustable horizontal aluminum louvres. It is suitable for a variety of applications, providing flexibility in air diffusion. The grille can be mounted using clip-ons or hidden screws. For ceiling installation or when used with a control damper, hidden screws are recommended. Mounting the grille with a plenum box is possible only with clips and without a mounting frame.
The DR grille is best suited for comfort environments, such as offices, schools, retail stores, restaurants and hotels.
