Dampers SF
SFDR fire dampers
SFDR fire dampers are used in offshore, marine and navy ventilation systems. The dampers are type-approved according to A-0 (A-60). The dampers can be installed in rectangular ducts. The dampers have a fusible link and prevent the spread of fire and smoke within the ventilation ductwork. The dampers can be welded directly on the bulkhead (as penetration) or installed in the ducting system with the optional flange. The dampers with non-standard dimensions are available on request. The dampers begin to close when the air pressure is below 1.5 bar and closes below 0.5 bar.
- Type-approved by most recognized classification societies: class A0 and A60 (A60 insulation in all cases).
- The damper has an indicator which shows whether the damper is open or closed.
- Nominal fuse release temperature: 72 ºC.
- For MED certificate, use a damper of 900 mm, including coaming and A60 insulation.
- Automatic electrical, pneumatic or spring operation system available.
