A fire and smoke damper is an essential component of a building’s fire safety system. It is a device that is installed in the ducts of a building’s heating, ventilation, and air conditioning (HVAC) system. The purpose of a fire and smoke damper is to prevent the spread of smoke and fire through the ducts of the HVAC system. The damper is designed to close automatically when it detects the presence of smoke or heat, thereby preventing the spread of fire and smoke throughout the building. Fire and smoke dampers are an important part of any fire safety system and are required by building codes in many areas. They are typically made of steel or aluminum and are designed to be both fire and smoke resistant. Fire and smoke dampers are an important part of any fire safety system and should be inspected and maintained regularly to ensure that they are working properly.
