Io Hvac Controls SC-ZD-09 Modulating Zone Damper 9 in

Product Description

The IO HVAC CONTROLS SC-ZD-09 is a modulating commercial zone damper designed to regulate airflow in zoned HVAC duct systems. It operates by adjusting blade position across a range of positions rather than simple open/close switching, allowing precise airflow control in variable-air-volume and multi-zone applications. At 9.125 inches wide, 8.125 inches high, and 9.125 inches deep, the unit fits standard commercial duct configurations. Weighing 6.3 pounds, it is sized for commercial-grade installation. Licensed HVAC technicians and sheet metal contractors are the typical installers for this type of zone control hardware.

The SC-ZD-09 is suited for commercial multi-zone HVAC systems where independent room or area temperature control is required. Modulating dampers of this type are commonly used in variable-air-volume systems, rooftop unit zoning applications, and commercial air handler distribution networks. The 9-inch round or duct-matched opening size targets mid-range commercial duct trunk and branch configurations. It is appropriate for light commercial buildings, retail spaces, office environments, and similar applications requiring zoned airflow management.

Key Features

• Modulating operation allows continuous blade positioning for precise airflow control, not limited to full-open or full-close
• 9-inch nominal size fits standard commercial duct branch and trunk openings
• Compact footprint at 9.125 x 8.125 x 9.125 inches suits tight mechanical space installations
• Commercial-grade construction at 6.3 pounds supports demanding duty cycles
• Designed for integration into multi-zone commercial HVAC control systems

Compatibility

Designed as an OEM-style modulating zone damper for commercial HVAC zoning systems requiring a 9-inch nominal duct connection.

Installation Notes

Installation should be performed by a licensed HVAC technician or qualified sheet metal contractor. Power down the air handler and de-energize all control wiring at the panel before beginning damper installation or wiring. Secure the damper to ductwork using appropriate sheet metal fasteners and seal all joints with listed duct sealant or foil tape per applicable mechanical codes. Verify actuator control signal compatibility with the zone control panel before energizing the system.
