Io Hvac Controls zd-3612 Zone Damper 36x12 Inches

Product Description

The IO HVAC CONTROLS zd-3612 is a modulating rectangular zone damper sized at 36 inches by 12 inches, designed for commercial HVAC zoning applications. It controls airflow distribution within a duct system by modulating its blade position, allowing independent temperature management across multiple zones. Licensed HVAC technicians working on commercial variable-air-volume or multi-zone systems will find this damper suited to ducted supply or return applications where precise airflow regulation is required.

This damper is intended for commercial installations where rectangular ductwork in a 36-inch by 12-inch opening is used. Typical scenarios include multi-tenant buildings, office spaces, retail environments, and other commercial facilities that require zone-level airflow control. Its modulating design means it is compatible with zone control systems that send variable positioning signals rather than simple open/close commands, making it appropriate for more sophisticated HVAC configurations.

Key Features

• Rectangular profile sized at 36 inches by 12 inches for direct duct integration
• Modulating operation allows variable blade positioning for precise airflow control
• Commercial-grade construction suited to higher-demand HVAC zoning systems
• Designed for ducted air distribution in multi-zone commercial environments

Compatibility

Designed as an OEM-style modulating zone damper for commercial rectangular duct systems requiring a 36-inch by 12-inch damper opening.

Installation Notes

Installation should be performed by a licensed HVAC technician familiar with commercial zoning systems and applicable mechanical codes. Shut down the air handling unit and de-energize the zone control panel before installing or wiring the damper actuator. Ensure the duct opening dimensions match the damper face size before securing to avoid air bypass. Wiring to the zone controller should follow the controller manufacturer's specifications and local electrical code requirements.
