Io Hvac Controls D-Z1-1212 Zone Damper 12x12

Product Description

The IO HVAC CONTROLS D-Z1-1212 is a two-position zone one damper assembly designed for ducted HVAC zoning systems. Operating in a fully open or fully closed position, this damper controls airflow to a single zone, allowing the system to direct conditioned air only where it is needed. The 12 x 12 inch frame size fits standard rectangular ductwork of the same nominal dimension. At 7.32 pounds, the assembly is substantial enough for commercial-grade applications while remaining manageable for single-technician installation. HVAC technicians installing or servicing zoning systems will find this a direct-fit replacement or new-installation component.

This damper assembly is suited for residential and light commercial forced-air zoning applications where a dedicated zone one position is required. It mounts inline within rectangular supply or return ductwork measuring 12 x 12 inches. Two-position dampers are commonly paired with zone control boards and 24-volt actuators as part of a complete zoning package, making this a core component in multi-zone comfort systems that regulate airflow independently to separate areas of a building.

Key Features

• Two-position operation for straightforward open or closed airflow control
• 12 x 12 inch frame fits standard nominal rectangular ductwork
• 6 inch depth accommodates typical inline duct mounting clearances
• Sturdy construction at 7.32 pounds suitable for residential and light commercial use
• Zone one designation for use in structured multi-zone HVAC system layouts

Compatibility

Designed as an OEM-style replacement or new-installation damper assembly for two-position zoning systems using standard 12 x 12 inch rectangular ductwork.

Installation Notes

Installation should be performed by a licensed HVAC technician familiar with zoning system wiring and ductwork modification. Shut down the air handler and disconnect power to the zone control board before installing or replacing the damper assembly. Secure the unit inline within the duct run and verify actuator wiring connections comply with the zone control manufacturer's wiring diagram. Refer to local mechanical codes and the International Mechanical Code for duct penetration and support requirements.
