The RSKE/RSKM smoke exhaust dampers and the BSK-1, BSK-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 protec tion for the damper and its actuator. The grille has a single horizontal row of non-adjustable air flow guides fixed at 45°.
The grille can be made of galvanized steel (Zn), carbon steel with a spe cial coating (M), stainless steel (N) or aluminium (A).
The grille is attached directly to the damper flange by means of self-tap ping screws with the louvre shutters facing outwards.
