Description

The FD-C series Circular Single Blade Externally Resettable Combination Fire and Volume Control Damper is designed to prevent the spread of fire and smoke through circular ducts that pass through fire-rated walls, floors, ceilings, and cavity barriers.

ES classified fire damper with reduced smoke leakage characteristics (BS EN 1366-2). Size range available: 100mm to 315mm dia.

The FD-C Series can be installed from one side of the fire separation barrier without the need for fire-rated infill material.

The FD-C Series circular single blade Fire dampers are suitable for use in dryline walls and masonry/concrete walls and floors and cavity barriers and is independently 3rd party tested and certified to the following standards:

  • Fire resistance tested to BS EN 1366-2.
  • ES classified to BS EN13501-3 CE marked to BS EN 15650 Closed blade leakage Class 3 to BS EN 1751.
  • Damper casing leakage Class C to BS EN 1751. Normal operating conditions – up to a maximum of 1000Pa.
  • The patented single blade layered design is held open against a torsion spring that is released via a fusible link having an alloy component that melts at 72°C allowing the spring mechanism to close the damper.
  • The externally resettable damper assembly and fusible link design enables testing without the need for specialist tools or access panels. NB: Access panels may be required to comply with DW145 G.3.1.5.
  • For the protection of escape routes and areas with sleeping risk, the FSD-C damper should be used. Please refer Approved Document B (ADB).

Delivery is 2-3 days for our standard sizes 100mm dia, 25mm dia, 150mm dia, 160mm dia, 200mm dia, 250mm dia, 300mm dia, 315mm dia.
