The fire dampers FDA-BU are manufactured in the following nominal sizes: DN100, DN125, DN160, DN200. The fire dampers are equipped with a thermal fuse mechanism ensuring the damper switch to the safe position in case of reaching an ambient temperature equal to or higher than 72°C. The fire dampers allow using limit switches signalling closed position of the damper blade (1 limit switch) or blades (in case of using 2 limit switches). The casing is made from galvanised steel sheet; the fire damper blade is made from a silicate cement board.

The FDA-12 shut-off dampers may be used when the ventilation system passes through the vertical and horizontal building partitions, ensuring fire integrity E, fire insulation I, smoke-leakage S 120 - EI 120 (ve ho i↔o ) S, depending on the fire resistance class of the building partition. The subject of the present document covers the FDA-12 round shut-off fire dampers used in the general ventilation systems as protections that prevent smoke and fire from getting between the separated neighbouring fire zones.
