The KPD/KPDU smoke exhaust dampers and the KP-1, KP-2 wall-mounted fire-resisting dampers (1 flange) can be additionally equipped with a smoke exhaust grille.
The smoke exhaust grille is used to entirely block the external view of the damper internals in the absence of strict requirements to the unit appearance.
The smoke exhaust grille also doubles as unauthorized access protection for the damper and its actuator.
The grille has one row of non-adjustable horizontal air flow guides fixed at 45°.
The grille can be made of galvanized steel (Zn), carbon steel with a special coating (M), stainless steel (N) or aluminium (A).
The grille is attached directly to the damper flange by means of self-tapping screws with the louvre shutters facing outwards.
