NCA S100 • Fire damper CE marked

Fire damper CE marked

A CE marked fire damper, comprising a folding curtain type blade design. Constructed from galvanised steel as standard, with stainless steel optional, and available with 120 minute ‘E’ rated installations to suit masonry walls, drywall partitions and concrete floors. During normal conditions, the curtain type blade pack is recessed into the damper header and retained in place by a fusible link, leaving the duct open to airflow. Upon exposure to temperatures exceeding the temperature rating of the fusible link, the link will split, and the blade pack will be fully extended by springs to shut down the duct. Series 100 fire dampers are designed to be used as part of building compartmentalisation, this being the process of constructing a building with zones. The purpose of this is that if a fire starts in any one zone, it is contained within that zone and not allowed to spread, thereby potentially savings lives, limiting damage to the building and making the job of fire fighters easier. It is useful to think of fire dampers as the ductwork equivalent of fire doors, allowing an unrestricted flow of air during normal operation, but shutting down a potential transmission route in the event of fire.
