Io Hvac Controls zd-22 Zone Damper 22 Inches Commercial

Product Description

The IO HVAC CONTROLS zd-22 is a 22-inch modulating zone damper designed for commercial HVAC zoning systems. Zone dampers control airflow distribution across multiple zones in forced-air systems, allowing independent temperature management in different areas of a building. The zd-22 is built for commercial applications where precise, modulating control is required rather than simple open-close operation. Licensed HVAC technicians typically source and install this type of damper as part of a multi-zone ductwork system paired with a compatible zone controller and thermostat network.

The zd-22 is intended for commercial forced-air HVAC installations where 22-inch duct openings are present. Modulating dampers like this one allow the zone controller to position the blade at varying degrees of opening, delivering proportional airflow rather than full-on or full-off delivery. This makes them well-suited for larger commercial spaces with variable load requirements across zones. No specific compatible models or controllers are listed in the available product data.

Key Features

• 22-inch size fits commercial duct openings requiring a full 22-inch damper blade
• Modulating operation allows proportional airflow control between fully open and fully closed positions
• Commercial-grade construction suited for higher-demand HVAC zoning applications
• Designed for integration into multi-zone forced-air systems with compatible zone control panels

Compatibility

Designed as a commercial-grade modulating zone damper replacement or new-installation component for 22-inch duct openings in commercial forced-air HVAC zoning systems.

Installation Notes

Installation should be performed by a licensed HVAC technician familiar with commercial zoning systems and ductwork. Power down the air handler and zone control panel before connecting or disconnecting damper wiring. Ensure the damper actuator signal type matches the zone controller output before wiring. Follow local mechanical codes and the zone controller manufacturer wiring diagram for proper low-voltage control connections.
