Fire and Smoke Dampers
FDO A0(A60) FIRE DAMPER
FDO fire dampers are type-approved class A0(A60) fire dampers for use in marine and offshore ventilation systems.
The FDO can be installed in circular ducts.
All fire dampers have a fusible link and they prevent the spread of fire within the ventilation ductwork.
When the blade is 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.

• Fixed frame of painted, galvanized or stainless steel. Blades stainless or galvanized steel. Flanges available as an option.
• Blade contains seals (effective up to 270 ºC)
• Nominal fuse release temperature 50 ºC, 74 ºC or 100 ºC. Other temperatures available.
• Very low leakage
• Automatic electrical, pneumatic or spring operation system available
• Maximum duct pressure for damper construction 5000 Pa and maximum air velocity 15 m/s
FDB 2A0(A60) FIRE AND SMOKE DAMPER
FDB2 fire dampers are type-approved class A0(A60) fire and gas dampers for use in offshore, marine and navy ventilation systems.
The FDB2 can be installed in rectangular or circular ducts.
All fire dampers have a fusible link and they prevent the spread of fire and gases 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.
