They are designed with high ventilation capacity. The dampers can protect people and equipment from explosions or momentary pressure change (e.g. tornadoes, etc.). When an explosion occurs, the valve will close instantly under the action of the shock wave; when the shock wave disappears, the valve will be automatically restored. They are mainly used in refineries, oil & gas, nuclear power plants and some other facilities which are at risk of explosions. They are installed on the air openings (air inlet and air outlet) of the facilities.

Expansion Chambers RK

Expansion chambers RK type are used to reduce the blast wave pressure after the blast dampers. Our range includes three types of metal expansion chambers: RK-0.5 (volume 0.5 m3); RK-2-I (volume 2 m3, air inlet from the side) RK-2-II (volume 2 m3, air inlet from the top). On request, it is possible to manufacture the RCF-6 product with built-in prefilters.
Other spaces can be used as expansion chambers – reinforced concrete rooms, sections of the air duct, and other.
