Io Hvac Controls D-14-PO Round Zone Damper 14 in

Product Description

The IO HVAC CONTROLS D-14-PO is a 14-inch round, two-position zone damper configured for powered-open operation. It controls airflow in zoned HVAC duct systems by opening on demand and closing when power is removed, providing reliable on/off airflow management. The damper ships at approximately 10 pounds and fits within an overall package envelope of 17 inches wide by 14 inches high by 17 inches deep. Licensed HVAC technicians and sheet metal contractors are the primary installers for this type of zone control component.

This damper is suited for residential and light commercial forced-air zoning applications where round ductwork is used. It is typically installed inline in a supply or return duct branch to serve a single zone controlled by a zone panel or thermostat. The powered-open, spring-return or gravity-close design makes it appropriate for fail-closed zoning strategies, where loss of power defaults the zone to a closed state.

Key Features

• 14-inch round duct diameter for direct inline duct installation
• Two-position operation: fully open or fully closed for straightforward zone control
• Powered-open actuation - closes automatically when power is removed
• Fail-closed behavior supports safe default operation in zoned systems
• Sturdy construction at 10 pounds suited for long-term duct service

Compatibility

Designed as an OEM-style replacement or new-installation zone damper for 14-inch round duct systems in residential or light commercial forced-air zoning setups.

Installation Notes

Installation should be performed by a licensed HVAC technician familiar with zoned forced-air systems. Shut down the air handler and de-energize the zone control panel before installing or wiring the damper. Secure the damper in the duct run according to the manufacturer's instructions and local mechanical code requirements before making low-voltage control wiring connections. Verify correct actuator voltage and wiring polarity at the zone panel before restoring power.
