mcr FID B cut-off dampers are intended for installation in fire ventilation systems operated manually (feature MA) and automatically (feature AA).

They support single fire zones, as well as several zones within a single facility.

They prevent the spread of fire, smoke and fire gases to neighboring zones. The dampers can operate in so-called mixed systems.
