A smoke fire damper is an important component of any building’s fire safety system. It is a device that is installed in the ductwork of a building’s heating, ventilation, and air conditioning (HVAC) system. Its purpose is to prevent the spread of smoke and fire through the ducts in the event of a fire. Smoke fire dampers are designed to close automatically when a fire is detected, cutting off the airflow and preventing the spread of smoke and fire. They are also designed to open when the fire is extinguished, allowing the air to flow again. Smoke fire dampers are an essential part of any fire safety system and should be regularly inspected and maintained to ensure they are working properly.
