Io Hvac Controls SC-ZD-1006 Modulating Zone Damper

Product Description

The IO HVAC CONTROLS SC-ZD-1006 is a modulating zone damper designed for commercial HVAC zoning applications. It controls airflow through a 10 x 6 inch duct opening by modulating blade position across a continuous range rather than simple open/close switching. This allows precise zone-by-zone airflow management in variable air volume (VAV) and zoned forced-air systems. Licensed HVAC technicians install this damper as part of a multi-zone control system to balance supply air distribution across a building. The unit weighs 6.4 pounds and has an overall body dimension of 5.875 x 5.875 x 9.875 inches.

This damper is suited for commercial zoning installations where individual zones require independent airflow modulation rather than binary on/off control. Typical applications include multi-zone rooftop unit systems, commercial VAV retrofits, and zoned split systems in light commercial buildings. It fits into 10 x 6 inch rectangular duct runs and is installed in-line between the supply trunk and the branch duct serving the zone. HVAC controls contractors and commercial service technicians are the primary installers of this unit.

Key Features

• Modulating operation for precise airflow control across a continuous range
• Designed for commercial HVAC zoning systems
• 10 x 6 inch duct opening for standard rectangular branch duct installations
• Compact body profile at 5.875 x 5.875 x 9.875 inches for tight mechanical spaces
• Rated installation weight of 6.4 pounds for straightforward single-technician handling

Compatibility

Designed as an OEM-style modulating zone damper for commercial rectangular duct systems requiring a 10 x 6 inch inline damper with modulating control capability.

Installation Notes

Installation should be performed by a licensed HVAC technician familiar with commercial zoning control wiring and duct fabrication. Shut down and de-energize the air handling unit and all associated zone control panels before beginning installation. Secure the damper to the duct section per the manufacturer instructions and verify control wiring connections comply with applicable NEC requirements before restoring power. Confirm modulating actuator response and full blade travel during system commissioning.
