Io Hvac Controls HD-BM-NA-2210 Zone Damper 22x10

Product Description

The IO HVAC CONTROLS HD-BM-NA-2210 is a two-position zone damper designed for use in rectangular HVAC duct systems to control airflow distribution across independently conditioned zones. Sized at 22 x 10 inches, this bottom-mount unit ships without an actuator, allowing installers to pair it with their preferred 5/8-inch or 1/2-inch shaft-compatible actuator. The damper blade assembly provides reliable open/closed operation, making it a standard choice for residential and light commercial zoning applications where proportional control is not required. Licensed HVAC technicians install this component as part of a complete zoning panel system.

This damper is suited for residential and light commercial forced-air systems where multiple zones require independent temperature control. The bottom-mount configuration fits duct runs where top access is restricted or impractical. Because no actuator is included, the installer selects and mounts the appropriate two-position or spring-return actuator for the application. It is typically installed in supply duct branches controlled by a zoning panel and thermostat network.

Key Features

• Two-position operation for straightforward open/closed airflow control in zoned systems
• 22 x 10 inch duct opening size for standard rectangular duct installations
• Bottom-mount design accommodates duct runs with limited top clearance
• No actuator included, allowing field selection of 5/8-inch or 1/2-inch shaft-compatible actuators
• Weighs 9.04 pounds for straightforward handling during installation

Compatibility

Designed as an OEM-style replacement or new-installation zone damper for rectangular supply duct zoning systems in residential and light commercial forced-air HVAC applications.

Installation Notes

Installation should be performed by a licensed HVAC technician. De-energize the air handler or furnace and disable the zoning panel before beginning work. Secure the damper to the duct section following sheet metal fabrication practices, and verify the shaft orientation aligns with the actuator mount before final assembly. Refer to local mechanical codes and the zoning panel manufacturer guidelines for wiring and control sequencing.
