Fire dampers are passive fire protection products used in heating, ventilation and air conditioning (HVAC) ducts to avoid the spread of fire inside the ductwork and prevent it from spreading to the adjacent compartments. When a rise in temperature occurs, the fire damper closes, usually activated by a thermal element which melts at temperature higher than ambient but low enough to indicate the presence of a fire, allowing springs to close the damper blades.
