Fire Damper
Critical Fire Safety Components for HVAC Ductwork Systems
FIRE & SMOKE CONTAINMENT SYSTEMS
Fire Damper
Fire Dampers are critical safety devices installed in HVAC ductwork to prevent the spread of fire and smoke through ventilation systems. They automatically close when triggered by heat or smoke detection systems, compartmentalizing fire zones and protecting life and property.
