Io Hvac Controls SC-ZD-1206 Commercial Zone Damper

Product Description

The IO HVAC CONTROLS SC-ZD-1206 is a modulating zone damper designed for commercial HVAC zoning applications. It provides precise airflow control within duct systems by modulating blade position across a full range of travel, rather than operating in a simple open/closed mode. This makes it well suited for variable air volume and multi-zone systems where accurate zone-by-zone airflow management is required. The damper measures 12 x 6 inches in duct opening size and weighs 6.5 pounds. It is typically installed by licensed HVAC contractors during new construction or retrofit of commercial zoning systems.

This damper is intended for commercial zoning installations where modulating control is required rather than two-position switching. Typical applications include multi-zone rooftop unit systems, commercial VAV retrofits, and zone control panel integrations in light commercial buildings. The 12 x 6 inch size fits standard rectangular duct branches common in commercial trunk-and-branch ductwork layouts. It is paired with a compatible zone control panel or modulating actuator controller to achieve proportional airflow regulation across individual zones.

Key Features

• Modulating operation for precise, proportional airflow control across the full damper travel range
• 12 x 6 inch duct opening size suited to common commercial branch duct applications
• Compact body dimensions of 5.875 x 5.875 x 11.875 inches for installation in tight duct spaces
• 6.5 pound unit weight supports secure mounting without excessive structural load on ductwork
• Designed for commercial zoning systems requiring variable airflow management

Compatibility

Designed as an OEM-style modulating zone damper for commercial HVAC zoning systems requiring a 12 x 6 inch rectangular damper with proportional control capability.

Installation Notes

Installation should be performed by a licensed HVAC technician familiar with commercial zoning systems and local mechanical codes. Disconnect and lock out power to the air handling unit and zone control panel before beginning installation. Ensure the duct opening is cut to the correct rough-in dimensions before inserting the damper, and verify actuator wiring connections against the zone control panel documentation before restoring power. Do not operate the damper manually against actuator resistance, as this may damage the blade mechanism.
