Duct Grille Or Universal Grille

This grille is specifically designed for direct mounting on rigid round duct, with a curved face.

The frame and blades are of high quality extruded aluminum profiled construction with the advantages of corrosion resistance and rigidity.

Grilles have two sets of parallel aero foil blades with one set mounted horizontally on the front and other set vertically at the rear.

Frame is separated from the aero foil deflection blades by nylon bushings. This method of assembly ensures quiet, smooth and rattles free operation.

Deflection blades can be adjusted manually and individually, to provide air deflection in both horizontal and vertical planes.

Grilles are rigidly fixed with opposed blade damper by grippers. Damper blade is screw operated from the face opening.

Foam gasket is sealed around the back of the frame as option to avoid air leakage.
