HVAC fire dampers are an important component of any HVAC system. They are designed to close automatically when a fire is detected, thus preventing the spread of smoke and flames throughout the building. This is an essential safety feature, as it helps to contain the fire and minimize the damage caused by it. HVAC fire dampers are typically installed in the walls and ceilings of buildings, and they are usually connected to a fire alarm system. When the fire alarm is triggered, the dampers close, cutting off the air supply to the affected area. This helps to contain the fire and prevent it from spreading. HVAC fire dampers are also used to control the flow of air in a building, as they can be adjusted to regulate the temperature and humidity levels. By controlling the flow of air, they can help to improve the overall comfort of the building.
