Air Vent Supply Air Grille Made of high-quality extruded aluminum profile. All sizes are available. Supply air grille (HVAC part, air register, double deflection supply air grille). The aluminum grille comes in two models: double deflection grille and single deflection grille. For double-layer products, the long blades are on the front while the short ones are at the back. To reduce flow resistance and noise, blades can be designed with a streamlined shape. The double deflection grille is commonly used in hotel rooms for supplying conditioned air. It has two sets of adjustable blades, allowing users to easily control airflow direction by adjusting blade orientation. To secure the grille in place, we provide easy-to-use mounting clips that save installation time. These uniquely shaped blades are made from high-quality plastic using innovative production technologies. Features: * The rectangular double deflection grille is suitable for both supply and extract air applications in comfort zones and industrial areas. It is a ready-to-install component consisting of a border and individually adjustable horizontal and vertical double-layer blades. * Directed supply air discharge for mixed flow ventilation. * Blades are individually adjustable to meet different local requirements. * Suitable for wall installation. * Made of extruded aluminum, powder-coated. * Concealed fixing or countersunk holes screw fixing for installation into an installation sub-frame or onto an installation surface. Color: * White: RAL 9010, RAL 9016, RAL 9003 * Anodized Structure: * Two rows: blades are movable on both horizontal and vertical lines.
