1 Dimensions B+0 A+0 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 hot-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. A x B = Cutting dimension Screws included. BxA 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.

3 Technical data Effective speed v 0 The diagram for throw (see next page) specifies effective speed v 0 [m/s] as a function of the volume flow q [m /h, l/s] for each grille size with 0 o bar setting. Air jet dispersal >00 b v = 0, l 0, Throw l 0. The diagram for throw (see next page) specifies the throw l 0. [m] at an average terminal velocity of 0. m/s, 0 o bar setting without ceiling effect. (Distance from grille to ceiling greater than 00 mm.) l b l 0 b v l b = 0, l 0, Table : Correction for dispersal x b h Bar setting Correction factor V 0 Correction factor l 0,, 0, Ceiling effect If the distance from grille to ceiling is less than 00 mm, the throw l 0. must be multiplied by.. Total pressure p t The diagram "Pressure sound level" page states the grille s total pressure p t [Pa]. Sound effect level L WA The diagram "Pressure sound level" states the grille s sound effect level L WA [db(a)] at a free area of 0.0 m. Table : Correction for free area Correction free area Duct speed v k Pressure and sound effect level are stated for different duct speeds v k [m/s]. For duct speeds v k < m/s, the sound values L WA must be corrected by - db. The diagrams on the following pages are in table form. See dimensioning tables.
