lindab | we simplify construction Circular duct grille RGS Dimensions B+30 A+70 47 A×B Description RGS is a rectangular ventilation grille with vertical adjustable bars for direct installation in circular ducts. The grille can be used for both supply and exhaust air. The grille can be supplied with horizontal directional bars, straight or slanting sliding damper or blade damper. The grille is designed so that the grille flanges always fit tight to the duct regardless of the duct diameter. RGS is made of galvanised steel plate and is put together without welding. This means that the grille can be used without further surface treatment. The exterior of the grille thus matches the duct surface. • Can be used for both supply and exhaust air • Installed directly in circular duct • Can be fitted with many types of accessory Maintenance The grille should be removed to gain access to the duct.
