Blade damperDGAN

The opposed blade damper DGAN can be fitted to the AD, AL, AR and AC aluminium grilles.
The opposed blade damper is held in place by clips, for fixing the damper to the grille.
The DGAN dampers are made entirely of galvanized steel and have mechanism for opening and closing all the damp-er blades simultaneously (by using a screwdriver).
DGAN is provided with spring wire to prevent the blades from clattering.
