Double Deflection Grilles with Damper

Ventilation Ducting  | Ventilation Grilles & Louvres | Grilles & Louvres Stock | Double Deflection Grilles |  Double Deflection Grilles with Damper



Double deflection grilles are primarily designed as supply grilles. They can be used in walls, ceilings, or installed directly into ductwork. They have two banks of movable blades set 90° to each other which allows for a great deal of directional adjustment and throw variation. Adjustment can be made by directly turning the blades by hand.

The damper fitted to the rear of the grille allows for volume control and can be adjusted using a screwdriver on the worm screw located through the front face and to one corner. Typically a clockwise turn will open the damper.

Listed sizes are nominal and refer to duct/aperture size; they do not include the flange. For overall size add 45mm.
