Where fire dampers are used and what they accomplish?

Fire dampers are used in HVAC systems within buildings to prevent the spread of fire and smoke through ductwork. They are installed at points where ducts penetrate fire-rated walls or floors, automatically closing in the event of a fire to contain the flames and reduce smoke migration. This helps to maintain the integrity of fire barriers and protect occupants, property, and facilitate safe evacuation during emergencies. Additionally, fire dampers contribute to compliance with building codes and fire safety regulations.
