Ship fire damper FEX

The Halton FEX fire dampers are type-approved class H0(H120) fire dampers for use in offshore, nuclear and navy ventilation systems. FEX dampers are used to protect the integrity of bulkheads where they are penetrated by ventilation ducts. The Halton FEX dampers can be installed in rectangular or circular ducts. Dampers have a fusible link and they prevent the spread of fire and gases within the ventilation ductwork. When the blades are in a open position, the device does not cause significant pressure loss, noise or flow disturbance. FEX dampers are set from outside and are suitable to be installed in bulkheads. An open-closed label is visible on the outside of the damper.
