FDA – A0(A60) Fire and gas damper

• Type-approved fire damper by most recognized classification societies: A0 without insulation, A-15 to A-60 when suitably insulated
• Available as ATEX certified
• Blades contain stainless steel spring seals for low leakage in normal conditions and thermal expansion graphite seals (effective from 150ºC) to seal the damper in case of fire. Silicon sealing as an option.
• Closed damper fulfills the requirement of leakage class 3 (EN1751:2014) > 300×300 mm and for size > 200×200 mm (silicon seals). Casing leakage class C.
• Nominal strip fuse release temperature 50ºC, 74ºC or 100ºC. Other temperatures available.
• Nominal glass bulb fuse release available as an option with temperatures 68ºC or 93ºC. Other temperatures available
• Low weight due to double skin blade structure
• Electrical or pneumatic operation system available
• Maximum duct pressure for damper construction 5000 Pa and maximum air velocity 15 m/s
• Normal operation temperature for damper between -50ºC to +80ºC. Actuator and component selection can have an effect on this temperature range. Other temperatures available on request.

Halton FDA fire dampers are type-approved class A0(A60) fire and gas dampers for use in offshore, marine and navy ventilation systems. The FDA 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. An open-closed indicator is visible on the outside of the damper. Fire dampers with non-standard dimensions can be supplied on request.

FDA fire dampers meet international standards for both rectangular (width B 200-1200 mm with 25 mm division and height H 200-1600 mm with 50 mm division) and circular ducts (Ø200-1250 mm). Modular constructions up to 2500×2600 mm available.
Non-standard dimensions and flange drilling available on request. Standard flanges and drilling according to ISO 15138 standards. Frame thickness 3 mm or 3-5 mm according to SOLAS.
Blades are made of two sheets, each of them being 1 mm thick (sandwich design).

Halton FDA is available with following actuators:

• FDA-EL: Electrical spring return actuator; standard actuators being 24 VAC/DC or 230 VAC or 120 VAC. Depending on the choice of actuator, the actuator might contain built-in open-closed limit switches. Separate junction box included in the EL-model. A wide range of Ex actuators available, including a one second closing time function as an option.
• FDA-PNR: Pneumatic rotating actuator

In the event of a temperature rise in ductwork:
