Automatic Vent Damper- A device installed in a furnace or boiler’s venting system to restrict the loss of heat after the furnace or boiler has been shut off. Vent dampers are usually used in conjunction with an intermittent ignition device (IID), but can be used with standing pilot flames as well. Vent dampers often ship on new furnace and. A zone damper (also known as a Volume Control Damper or VCD) is used specifically to control the flow of air in an HVAC heating or cooling system. HVAC systems are typically divided up into multiple zones. This will allow users of the system to direct heat or cool air to areas high occupancy areas, allowing the unoccupied areas to cool down.
A zone damper (also known as a Volume Control Damper or VCD) is a specific type of damper used to control the flow of air in an HVAC heating or cooling system. In order to improve efficiency and occupant comfort, HVAC systems are commonly divided up into multiple zones. For example, in a house, the main floor may be served by one heating zone while the upstairs . Hydraulic U-trap Silencers Filters Dampers Access doors Flexible connectors Clamps Plate heat exchangers Mixing chambers Fire damper PL Water heaters Electric heaters Water coolers Freon coolers Mixing sets Air flow regulators Kitchen exhaust hoods .
e.g. If one room is too cold, but the other ones are fine, the system will shut the dampers to the other rooms, and then fire up the heater so just the one room is heated. More sophisticated zoning systems for larger house will include multiple heating/cooling units (e.g. one for the upstairs and one for the downstairs).

When a HVAC damper goes bad, proper airflow is no longer achieved through the duct work. Heating, ventilation, and air conditioning (HVAC) is the technology of indoor and vehicular environmental comfort.
Its goal is to provide thermal comfort and acceptable indoor air system design is a subdiscipline of mechanical engineering, based on the principles of thermodynamics, fluid mechanics and heat transfer."Refrigeration" is sometimes. A central air conditioning system distributes the cooled air throughout your house via ducts.
How much air each room gets depends on the damper settings. These plates, which are located inside the ducts, are adjustable.
They can be opened or closed as much as needed to make the rooms they control comfortable. Installing dampers inside your ducts is the most common way to add zones to an existing system.
However, your blower can only operate at % capacity. The static pressure will be too intense for just the ductwork associated with a single zone (50% or so of your total ductwork). You'll need a way to redirect the excess air.
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.
Dampers may also be used to help control the rate of combustion in fuel burning equipment. Zone Dampers are used to control system supply duct airflow. ZONEFIRST is a leading manufacturer of HVAC Zone Dampers, Zone Controls and Zoning Systems. CALL TODAY. By-Pass Sizing Calculator Often with zoning systems a By-Pass is needed to relieve excess air when only a small zone or number of small zones cannot deliver the required air flow thru the HVAC System.
