The Protecta FR Fire Damper is a proven passive fire protection solution designed to maintain fire compartmentation in ventilation systems where ductwork passes through fire-rated walls and floors.
This clearance listing is for a single variant only – 100mm diameter, supplied exclusively as a pack of 6 dampers, making it ideal for small-to-medium projects or specific upgrade works.
In the event of a fire, the damper activates automatically via intumescent graphite fins, expanding to seal the duct and prevent the spread of fire and smoke between compartments. Its mechanical, power-free design ensures reliable operation without the need for electrical connections or ongoing maintenance.
With a compact 150mm length, the damper allows for immediate duct bends after installation, making it particularly useful in space-restricted environments. It also supports installation within multi-service penetrations when used as part of a tested system.
Tested to the highest standards and CE-marked, the Protecta FR Damper provides dependable fire resistance and long-term performance in both residential and commercial applications.
