Fire Dampers and Valves

Fire Dampers and Valves

Grills, valves and fire protection dampers are one of the types of the ventilation system fire protection.

The valves are installed as ceiling-mounted diffusers or exhausts which look like standard elements which, however, close automatically in case of fire.

Depending on the requirements of the partition and support walls, the dampers have the fire resistance class EIS60, EIS,90 and EIS120 and are originally equipped with electrical actuators or "fuses" closing  the damper at the temp. of 72oC.

Each of the dampers is designed to be coupled with the spiral round ducts or rectangular ventilation ducts.
