Fire And Smoke Dampers
Critical safety devices that prevent the spread of fire and smoke through ventilation ducts, protecting all areas of your building.
Essential Duct Protection Systems
Fire and smoke dampers are passive fire protection devices installed in ductwork to automatically close when fire or smoke is detected, preventing the spread of flames and toxic gases through the building's ventilation system.
Our dampers comply with BS EN 15650 and BS 476 standards, providing reliable compartmentation and maintaining the integrity of fire-rated walls and floors.
