Ship fire damper FDL

Halton FDL fire dampers are type-approved classA0(A60) fire dampers for use in offshore, marine and navy ventilation systems. The FDL can be installed in rectangular or circular ducts. The FDL dampers are used to prevent the spread of fire within the ventilation ductwork. All fire dampers have a fusible link and spring return actuator.
