FSD-C Series Motorised Circular Fire Damper

FSD C Series circular single blade motorised fire dampers are designed to prevent the spread of both fire and smoke through circular ducts passing through fire rated walls, floors, ceilings and cavity barriers.

Tested and classified to ES rating under BS EN 1366 2, these dampers feature reduced smoke leakage performance and are available in sizes ranging from 100mm to 315mm diameter.

For ease of installation, the FSD C Series can be fitted from a single side of the fire separating barrier without the need for fire rated infill material.
