A damper is a valve or plate that stops or regulates the flow of air inside a duct, chimney, VAV box, air handler, or other air handling equipment. A damper may be used to cut off central air conditioning (heating or cooling) to an unused room, or to regulate it for room-by-room temperature and climate control.
A Lock-Top damper or energy-saving damper is a damper that is connected to the chimney system at the top of the flue. Like a throat damper, it has an easy-to-use cable for opening and closing the flue (donât worry â you wonât have to go up on the roof!), but unlike a throat damper, a Lock-Top damper provides an airtight seal.
