Combination fire and smoke dampers provide both fire and smoke protection for HVAC ductwork and air transfer openings that penetrate fire and smoke-rated walls and floors. Designed to help maintain the integrity of fire and smoke-resistance barriers, these dampers prevent the spread of flames and smoke between building compartments during a fire event. Combination fire and smoke dampers are UL 555 classified for fire protection and UL 555S classified for smoke leakage, making them a critical component of code-compliant life safety systems.
