A fire-rated damper is a crucial fire protection device installed within HVAC (Heating, Ventilation, and Air Conditioning) systems to prevent the spread of fire and smoke through ductwork.
When a fire occurs, the fire-rated damper automatically closes to seal off the ducts, acting as a barrier that limits the fire’s movement to other parts of the building.
These dampers are constructed from fire-resistant materials and have a specified fire rating indicating their ability to withstand high temperatures.
Fire-rated dampers are classified based on their location and function, such as curtain-style dampers for horizontal ducts and multilouver-style dampers for vertical applications.
Regular inspection, testing, and maintenance are essential to ensure fire-rated dampers operate effectively during an emergency.
Fire-rated dampers play a crucial role in passive fire protection, enhancing the overall safety of occupants and protecting property.
