Zone dampers as used in home HVAC systems are usually electrically powered. In large commercial installations, vacuum or compressed air may be used instead. In either case, the motor is usually connected to the damper via a mechanical coupling.
For electrical zone dampers, there are two principal designs.
In one design, the motor is often a small shaded-pole
synchronous motor combined with a rotary switch that can disconnect
the motor at either of the two stopping points ("damper open" or
"damper closed"). In this way, applying power to the "open damper"
terminal causes the motor to run until the damper is open while
applying power at the "close damper" terminal causes the motor to
run until the damper is closed. The motor is commonly powered from
the same *4 volt ac power source that is used for the rest of the
control system. This allows the zone dampers to be directly
controlled by low-voltage thermostats and wired with low-voltage
wiring. Because simultaneous closure of all dampers might harm the
furnace or air handler, this style of damper is often designed to
only obstruct a portion of the air duct, for example, *5%
