What is a Suncourt Motorized Damper?

Suncourt Motorized Dampers also known as Zone Dampers, Motorized Duct Dampers, or Automatic Dampers are mounted in ductwork to automatically shut off or open branches of the duct to airflow. They are available in normally open (power close) or normally closed (power open) configurations.

What would I use a Motorized Damper for?

  • Zone Control-Do you have a spare bedroom that you don’t want to fully heat or air condition because the room is rarely used? A Zone Damper will shut off air to that room’s registers and only allow air to flow again when temperatures in that room exceed or drop below your preset temperature. Zone Dampers are typically controlled by a thermostat or some type of master controller. Likewise Zone Dampers can control airflow to whole sections of a home or building to regulate temperature in those specific areas at certain times of the day, evening or the time of your choosing, which saves on heating and cooling bills.
  • Ventilation-Zone Dampers can open to allow temporary ventilation of homes, garages, greenhouses, or other rooms where fresh air intake or stale air outtake is required.

How does a Motorized Damper run?

Suncourt Automatic Dampers are 24-volt powered and require a transformer. Suncourt Zone Master Dampers are often installed by homeowners and have a transformer included in the box. Suncourt Pro Dampers are often installed by professionals and do not have a transformer included in the box. Automatic Dampers can be wired to 24-volt thermostats. Suncourt Automatic Dampers feature a soft-stop, freewheeling coupling between the motor and the damper shaft, which greatly improves life over other similar style dampers on the market. Suncourt Automatic Dampers feature a hysteresis motor that is designed to hold the damper closed or open with power indefinitely.
