SGR air supply/exhaust grilles are installed directly and lengthwise on the round ducts and fastened with screws. The grille has been designed so that the bezel flange fits tightly to the round surface of the duct, whatever the duct diameter. The grille is made of galvanized steel sheet without tack or seam welds. As a result, it requires no anti-corrosion protection and its finish matches that of the ductwork. The grille can be optionally fitted with single or double louvre blades positioned horizontally and vertically. The louvre blade angle is adjusted manually.
The air grille can also be fitted with the SGR-DA sliding angle damper. The grille can be finished by powder coating in any RAL colour.
