Fire and smoke dampers

Fire dampers are divided into two types – fire resistant dampers and smoke dampers. Fire resistant damper is a fire damper designed to cover the holes in those places, where vent canals pass through the overlays between floors, walls and partitions. Fire resistant dampers produced according to the features of resistance range may be of 30 minutes (ЕI 30), 60 minutes (ЕI 60) and 120 minutes (ЕI 120), round or square cut, mechanical with fusible element or electromechanical actuator.
Smoke damper is a fire damper designed to cover the holes in the enclosed structures of supply and removal canals of the emergency and anti-smoke vent systems. The dampers are operated by electromechanical actuator and produced of rectangular shape.
