Protecta FR Damper is used to fireproof ventilation ducts that penetrate fire rated constructions such as fire compartments and firewalls, preventing the passage of fire and smoke (surrounding and inside the ventilation duct). The product consists of a steel casing and contains horizontal steel blades, treated with a technically advanced heat expanding graphite which closes off the whole damper in a fire.
The aperture surrounding the dampers are fire sealed with Protecta fire stopping products. The damper can be installed in the fire seal and the ventilation ducting attached, or the damper can be connected to the ducting and then fire sealed. The aperture where the ducts pass through can include one or multiple ventilation ducts. One can also pass through other technical services such as cables, cable trays and pipes within the same aperture.
