FDO in picture with flanges (available as an option) Halton 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. • Type-approved by most recognized classification societies, class A0 - A60 fire damper when suitably insulated • Availabe as ATEX approved • 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 °C) • Nominal fuse release temperature 50 °C, 74 °C or 100 °C. 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 halton MARINE
