A plate or valve that closes the fireplace flue when the fireplace is not in use. You must fully open it before lighting the fire.
Found at the exit point of ductwork, this plate usually contains grates that can be opened or closed to control the flow of air into a zone.
The movable plate in a fireplace, which allows smoke to travel up the chimney's flue.
Devices in duct work regulates airflow. Effective in controlling airflow for zoning.
A baffler used to open or close the throat of ventilators.
A device for adjusting or for closing the opening in the stack of the kiln to stop the escape of heat.
A device that is located in ductwork to adjust air flow. This movable plate opens and closes to control airflow. Dampers are used effectively in zoning to regulate airflow to certain rooms. There are basically two types of dampers: Manual and motorized. A manual damper generally consists of a sheet metal (or similar material) flap, shaped to fit the inside of a round or rectangular duct. By rotating a handle located outside of the duct a technician can adjust (see Balancing) air flow to match the needs of a particular area or room. A motorized damper is generally used in a zoned system (see Zoning) to automatically deliver conditioned air to specific rooms or zones. In particular, the following types, can be distinguished: Multiple leaf dampers, comprising of a number of blades (or shutters) of opposed or parallel leaf type. Single leaf dampers (the flap being mounted at one end), commonly called splitter dampers. Hit-and-miss dampers, having two or more slotted slide mechanism. Butterfly dampers, with two flaps in "V" arrangement.
A device used to vary airflow through an air duct. A damper may be immovable, manually adjustable, or part of an automated system.
Valve for controlling airflow.
An adjustable plate for controlling draft.
A moveable blade located in the throat of the fireplace. Designed to impede air flow into the chimney.
a plate which is adjusted inside the flue or vent of a fireplace or furnace that controls the draft from the flame or that may prevent loss of conditioned air from within a building or back drafting of outside air
Device for controlling air flow.
A device within the exhaust vent that can restrict the air flow through the exhaust vent.
A device to regulate flow of gas through a stack or duct and to control draft in a heater. A typical damper consists of a flat plate connected to a shaft, which can be rotated, similar to a butterfly valve. A damper may have more than one blade.
A metal door placed within the fireplace chimney; normally closed when the fireplace is not in use

A valve, or plate, used to regulate the flow of air or other gases.
A manually or automatically controlled device to regulate draft or the rate of flow of air or combustion gases. Volume damper. A device that, when installed, will restrict, retard or direct the flow of air in a duct, or the products of combustion in a heat-producing appliance, its vent connector, vent or chimney therefrom.
A valve to control air flow to or from any desired point.
A device for introducing a variable resistance of regulating the volumetric flow of gas or air.
A movable plate used to control air flow; in a wood stove or fireplace, used to control the amount and direction of air going to the fire.
In a duct or chimney, a damper is a valve or plate that stops or regulates the flow of air. 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. In the case of cutting off air, it is often manual, turned by a handle on the outside of a duct.
