Fire dampers are shutters in ventilation duct systems that preventing spreading the fire and combustion gases from one fire
compartment to the other one by shutting of closing the air duct in the positions of fire separating constructions. Dampers blade
closes automatically air duct using a shutting spring or an return spring of its actuating mechanism in case of fire. The return spring
of the actuator is started when the thermal fuse is activated. In the case of thermos electrical fuse the activation (closing)
procedure starts, when a reset button on fuse is pushed or when a power supply of the actuating mechanism is stopped. In case
of mechanical control with thermal fuse, the return spring is activated after the moment, when thermal fuse is melted. The
damper´s blade is sealed with a silicon gasket/packing preventing smoke penetration after closing the blade. At the same time,
the damper´s blade will be tighten by intumescent tape, which will be expanding in the case of fire. Dampers have no inspection
door. For inspection of the damper, there is an inspection hole for camera. For others service works there must by installed
inspection door externally on the duct, next to the fire damper. The damper is equipped with additional collar, around the position
of the blade. On the collar, there are positioned several metallic plates (fixtures for easy installation on the wall or ceiling construction.

Fire damper´s proper functioning is determined by the following working conditions:
■ Maximum air speed: 12m/s.
■ Maximum pressure difference: 2500 Pa.
■ Operation of the dampers does not depend on the direction of air-flow (circulation).The dampers can be located in any
(arbitrary) position.
■ Dampers are suitable for ventilation air systems not containing any abrasive, chemical and adhesive particles.
■ Dampers are designed for macroclimatic areas with mild climate according to EN 60721-3-3.
■ Temperature in the place of installation is permitted to be in the range from - 30°C to + 50°C.
