Io Hvac Controls HD-2810-BM Zone Damper 28x10 Bottom Mount

Product Description

The IO HVAC CONTROLS HD-2810-BM is a rectangular two-position zone damper designed for forced-air HVAC zoning systems. It uses a 2-wire actuator to control airflow between open and closed positions, making it a straightforward solution for residential and light commercial zone control applications. The damper measures 28 inches wide by 10 inches tall in duct opening size and features a bottom-mount actuator configuration. At 9 pounds, it is built with the structural weight typical of a full-sized rectangular duct damper. Licensed HVAC technicians install this component during zone system commissioning or as a replacement in existing multi-zone ducted systems.

This damper is suited for rectangular supply or return duct runs in multi-zone forced-air systems. The bottom-mount actuator position is selected when duct layout or clearance conditions require actuator access from below. Two-position operation means the damper blade drives fully open or fully closed based on the zone controller signal, which is standard for on/off zone control rather than modulating airflow. It is appropriate for residential new construction, renovation zoning retrofits, and light commercial ducted HVAC applications.

Key Features

• Two-position (open/closed) operation for standard on/off zone control
• 2-wire actuator simplifies wiring to compatible zone control boards
• Bottom-mount actuator accommodates restricted overhead clearance installations
• 28 x 10 inch rectangular duct opening fits common residential trunk and branch duct sizes
• 9-pound construction provides durability typical of full-sized rectangular zone dampers

Compatibility

Designed as an OEM-style replacement or new-installation zone damper for rectangular ducted forced-air HVAC zoning systems using 2-wire actuator zone controllers.

Installation Notes

Installation should be performed by a licensed HVAC technician familiar with forced-air zoning systems and applicable mechanical codes. Power down the air handler and zone control panel before wiring the actuator. Confirm duct opening dimensions match the damper frame size before securing to the duct to avoid air bypass. Follow the zone controller manufacturer wiring instructions for the 2-wire actuator connection.
