A fire damper is an important component of a building’s HVAC system. It is designed to prevent the spread of fire and smoke from one area of the building to another. Fire dampers are typically installed in walls and ceilings, and they are usually made of metal. They are usually connected to the building’s fire alarm system, so that when the alarm is triggered, the fire damper will close automatically. Fire dampers are also sometimes used in combination with smoke dampers, which are designed to prevent the spread of smoke, but not necessarily fire. Fire dampers are an important part of any HVAC system, as they help to protect the building and its occupants from the dangers of fire and smoke.
