Spiral duct grilles - galvanised

Photo of product SGR


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

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.
