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 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.
FDO fire dampers meet international standards for circular ducts (Ø100-500 mm). Sizes Ø100 and Ø125 are not available of stainless steel. Sizes starting from Ø160 can be manufactured with 1 mm division. Flanges and drilling available as an option and according to ISO 15138 standards. Special flanges and drilling available on request. Frame material thickness 3 mm or according to SOLAS. Flap is made of two sheets, each of them being 1 mm thick (riveted together).
