What Is a Fire Damper?
A fire damper is a safety device designed to halt the spread of fire and smoke within a ductwork.
Fire dampers operate by detecting fire through sensors like temperature fuses or smoke detectors. Upon detection, they automatically close, acting on the signal from these sensors. They are commonly installed in various structures, including buildings, industrial sites, and transportation facilities. In these settings, fire dampers are essential in exhaust ducts, ventilation ducts, and air conditioning systems to block fire and smoke during a fire event.
Their mechanism is primarily based on automatic closure triggered by fire detection. When a fire is sensed, the damper promptly shuts, effectively impeding the passage of fire and smoke. A significant aspect of fire dampers is their autonomous operation, requiring no human intervention, thus playing a crucial role in fire containment by preventing the spread of fire and smoke.
