Halton FDK fire dampers are type-approved class A0(A60) fire dampers that are developed to be used in speed ferries and yachts where saving weight plays an important role. The FDK can be installed in rectangular or circular ducts. All fire dampers have a fusible link and they prevent the spread of fire within the ventilation ductwork. When the blades are in the open position, the device does not cause significant pressure loss, noise or flow disturbance. Fire dampers are set from outside and can be installed in any position. An open-closed indicator is visible on the outside of the damper. Fire dampers with non-standard dimensions can be supplied on request.
