Fire damper FDMR

Fire-fighting systems represent a specific range in accordance with the regulations. They are configured as elements of protection against fire and the passage of smoke, due to the smoke tightness required in the tests.

For an optimum fit with the duct, there are perimeter seals at both ends of the damper. Standard models: Model FDMR.01 Manual operation and thermal outside of the damper with case of protection.
