Io Hvac Controls SC-ZD-14 Modulating Zone Damper 14in

Product Description

The IO HVAC CONTROLS SC-ZD-14 is a 14-inch modulating zone damper designed for commercial HVAC zoning applications. It controls airflow distribution within a ductwork system by modulating blade position in response to a zone controller or building automation signal. The unit measures 14 inches wide by 8 inches high by 14 inches deep and weighs 10.5 pounds. Licensed HVAC technicians and commercial mechanical contractors install this damper as part of a multi-zone air distribution system to balance supply air across independently controlled zones.

The SC-ZD-14 is suited for commercial variable air volume and zoned constant-volume systems where precise airflow control is required. Its 14-inch form factor fits standard rectangular duct openings of the same nominal size. Typical installations include light commercial office buildings, retail spaces, and multi-tenant facilities where independent room or zone temperature control is needed. A qualified mechanical contractor handles installation during new construction or retrofit duct modification projects.

Key Features

• 14-inch nominal duct size for direct fit into matching rectangular duct openings
• Modulating operation allows proportional blade positioning rather than simple open/close control
• Commercial-grade construction suitable for higher-demand zoning applications
• Compact depth of 14 inches supports installation in tight mechanical spaces
• 10.5-pound unit weight is manageable for single-technician overhead duct installation

Compatibility

Designed as an OEM-style replacement or new-installation modulating zone damper for commercial rectangular duct systems requiring a 14-inch nominal opening.

Installation Notes

Installation should be performed by a licensed HVAC technician familiar with commercial zoning systems and local mechanical codes. Shut down the air handling unit and de-energize all associated control circuits before cutting into ductwork or making wiring connections. Secure the damper to the duct with sheet metal screws and seal all joints with approved duct sealant or foil tape per SMACNA guidelines. Verify actuator signal type and control wiring with the zone controller manufacturer before completing the installation.
