Application

  • Suitable for internal fire zone compartmentalisation.
  • Certified for use in masonry walls, drywall partitions and concrete floors.

Description

A CE marked fire damper, comprising a folding curtain type blade design. 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 72°C the fusible 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, containing any potential fire within one zone and not allowing it to spread, thereby potentially savings lives, limiting damage to the building and making the job of fire fighters easier. Fire dampers allow an unrestricted flow of air during normal operation, but shutting down a potential transmission route in the event of fire.

  • CE marked curtain type fire damper.
