Io Hvac Controls HD-BM-NA-2606 Zone Damper 26x6

Product Description

The IO HVAC CONTROLS HD-BM-NA-2606 is a two-position zone damper designed for duct-mounted zoning applications in forced-air HVAC systems. Built for a 26-inch by 6-inch duct opening, this bottom-mount damper ships without an actuator, allowing the installer to pair it with a compatible actuator suited to the job. The 5/8-to-1/2-inch shaft accommodates standard actuator couplings used in residential and light commercial zoning systems. Weighing approximately 8 pounds, the unit is sized at 13 inches wide, 28 inches tall, and 7 inches deep in its packaged form. Licensed HVAC technicians handling zone system installations and replacements are the primary installers.

This damper is suited for residential and light commercial forced-air zoning systems where independent room or zone temperature control is required. The two-position design operates fully open or fully closed, making it appropriate for standard zone control applications managed by a zone control board and individual thermostats. The bottom-mount configuration positions the actuator mount at the base of the damper blade assembly, which suits specific duct orientations and equipment room layouts where top or side mounting is not practical.

Key Features

• Fits 26-inch by 6-inch duct openings for standard residential and light commercial zoning
• Bottom-mount actuator configuration for flexible installation in constrained duct layouts
• Ships without actuator, allowing pairing with installer-specified or job-specific actuator
• 5/8-to-1/2-inch shaft compatible with standard zone actuator couplings
• Two-position operation for fully open or fully closed zone control

Compatibility

Designed as an OEM-style replacement or new-installation zone damper for forced-air residential and light commercial zoning systems requiring a 26-inch by 6-inch two-position bottom-mount damper with a 5/8-to-1/2-inch shaft.

Installation Notes

Installation should be performed by a licensed HVAC technician familiar with zoned forced-air systems. Power down the air handler and zone control system before mounting or wiring any components. The actuator must be sourced and installed separately; verify actuator shaft compatibility with the 5/8-to-1/2-inch damper shaft before proceeding. Secure the damper into the duct section according to the manufacturer instructions and confirm blade travel is unobstructed before restoring power.
