Wall ventilation grille (SVR)

Wall ventilation grilles are used in exhaust or supply ventilation and air conditioning systems to regulate airflow and direct the air stream. They are made from extruded aluminum profiles with a powder-polymer coating. The grilles consist of a decorative frame to which horizontal or vertical directional louvers are attached. The louvers can be adjustable, allowing air distribution in one or two directions, or fixed, meaning they are non-movable. For smooth airflow regulation, a multi-blade damper can be used. The grilles are typically painted in RAL 9010, but can be coated in other RAL colors as well.
