Product Description
Castle Curtain Fire Dampers are passive fire protection devices installed in duct penetrations through fire-rated walls and floors. The curtain-style blade drops by gravity when the fusible link melts at 72°C, sealing the duct opening and preventing fire spread through the HVAC system. Available in 1.5-hour and 3-hour fire ratings per UL 555 and BS EN 1366-2.
