A fire dampener is a device that is designed to reduce the risk of fire spreading through a building or structure. It is typically used in places where there is a risk of fire, such as in factories, warehouses, and other industrial facilities. Fire dampeners are designed to limit the spread of fire by restricting the flow of air through a building. This is done by using a series of dampening materials, such as metal plates, which are placed between the walls of the building and the air. These materials act as a barrier, preventing the fire from spreading through the building. Fire dampeners are also used in residential buildings, such as apartments and condominiums, to help protect against the spread of fire. They are also used in public buildings, such as schools and hospitals, to reduce the risk of fire spreading. Fire dampeners are an important part of fire safety and can help to save lives in the event of a fire.
