Manual dampers are turned by a handle on the outside of a duct. In a chimney flue, a damper closes off the flue to keep the weather (and birds and other animals) out and warm or cool air in. This is usually done in the summer, but also sometimes in the winter between uses.

How does a manual damper work?
Manual dampers work by the homeowner twisting a screw to regulate the airflow that goes into a certain zone. Motorized dampers are more convenient for homeowners with a programmed HVAC zoning system, as they work in concert with the whole HVAC system and follow the home’s heating and cooling regime set by the owner.
What are the 3 types of dampers?
Some of the various types of dampers used in the HVAC system are mentioned below.
- Butterfly Flat Dish Damper. Butterfly dish dampers are mainly designed for high efficiency with less maintenance.
- Blade Dampers.
- Guillotine Dampers.
- Louver Dampers.
- Inlet Vane Dampers.

Where are manual dampers located?
Go into your basement or attic and find the dampers. Usually, they are positioned somewhere in the “take-offs” or “branches” of the duct system. With manual-type dampers, they have either a rod that you can adjust using a screwdriver or a lever that you can turn by hand.
What’s the difference between damper and dampener?
Actually, damper means that something is wetter than something else, more damp. A dampener is something that dampens, as in someTHING that makes something wet OR dampens vibration.
What is the purpose of a damper?
Dampers keep cold air out. When your chimney is not in use, the outside air can easily work its way in by coming down through the chimney. This makes your home cold and uncomfortable, and it causes your heating bills to increase fast.
What are the two basic style of dampers?
At the highest level, there are 2 distinctly different applications for dampers: HVAC (Heating, Ventilating, and Air Conditioning) applications and Industrial Process applications.
Do all HVAC systems have dampers?
Typically in most homes, your HVAC dampers are located in the main supply trunks. Some homes have no dampers at all. Hopefully most homes have a damper in each one of the supply ducts. Your home may have a supply duct go to the right and you might have one go to the left off of your furnace.
What is a butterfly damper?
Butterfly dampers are used to restrict the flow of materials in ducting systems where flow control and low leakage isolation are a priority. These dampers are especially useful in applications such as incinerators, balancing systems, control air systems, stack isolation, and scrubber systems.
Do you leave the damper open?
The damper should be kept open until all embers are finished burning to prevent smoke from escaping into the home. When the fireplace is not in use, the damper should always be closed. An open damper is like an open window, allowing large amounts of heat from the home to escape.
How do I know if my damper is open or closed?
Before lighting a fire, you can tell if the damper is open by placing your hand into the fireplace. If you feel a draft coming down the chimney, it is a good indicator that the damper is open. If you don’t feel any cold air coming down the chimney, it means that the damper is closed.
How are motorized dampers controlled?
Dampers are operated manually or automatic (motor driven). Automatic Dampers are used to constantly regulate airflow and are operated by electric or pneumatic (Air Pressure) motors – each controlled by a thermostat or building automation system.
How do you close a fresh air intake?
Closing the Supply of Air from Outside By blocking it, you could strain the system or, in the case of an intake serving a furnace, cause negative pressure that causes fumes and carbon monoxide to back up. That being said, you can safely close an intake vent by sliding the dampers into the closed position.
How do dampers work?
A shock absorber or damper is a mechanical or hydraulic device designed to absorb and damp shock impulses. It does this by converting the kinetic energy of the shock into another form of energy (typically heat) which is then dissipated.
