Choosing the right fire damper to protect your facility

Engineering Resources Ruskin

A fire damper is installed in fire-resistive-rated assemblies where ducts penetrate or there are air transfer openings. Its purpose is to close automatically on detecting heat and help prevent the spread of fire through the opening. It does so using a design intended to interrupt migratory airflow, resist the passage of flame and maintain the integrity of the fire-rated separation. By minimizing the spread of smoke and flames, dampers aid the evacuation of a building and can reduce reconstruction costs to building owners.
