Halton FDL fire dampers are type-approved classA0(A60) fire dampers for use in offshore, marine and navy ventilation systems. The FDL can be installed in rectangular or circular ducts. The FDL dampers are used to prevent the spread of fire within the ventilation ductwork. All fire dampers have a fusible link and spring return actuator. When the blades are in the open position, the device does not cause significant pressure loss 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. Fire dampers with non-standard dimensions can also be supplied on request.
The Halton FDL fire dampers are manufactured according to international standards for both rectangular (width B 100-1300 mm and height H 100-1200 mm, 1 mm division) and circular ducts (Ø100-1250 mm). Modular constructions are available for bigger sizes. Non-standard dimensions and flange drilling are available on request.
Standard flange width 27 mm. Flanges and drilling also available according to ISO 15138 standards.
Blades are made of two sheets, each of them being 1 mm thick (sandwich design).
Modular construction sizes up to 2660×2460 mm.
Frame material thickness 3 mm or 3-5 mm according to SOLAS.
