Io Hvac Controls MD-2612-BM Zone Damper 26x12 in Bottom Mount

Product Description

The IO HVAC CONTROLS MD-2612-BM is a rectangular 2-position zone damper sized at 26 inches wide by 12 inches tall, fitted with a Belimo 3-wire actuator in a bottom-mount configuration. Zone dampers are critical components in HVAC zoning systems, directing conditioned air to specific areas of a building by opening or closing on demand from a zone controller or thermostat. The Belimo actuator provides reliable spring-return or powered operation, depending on wiring configuration. Weighing 11 pounds, this damper is built for duct installation in residential or light commercial forced-air systems. Licensed HVAC technicians are the primary installers of this assembly.

The MD-2612-BM is suited for use in multi-zone forced-air HVAC systems where independent temperature control is required across different areas or rooms. The 26-by-12-inch rectangular form factor fits standard rectangular ductwork of that cross-section. The bottom-mount actuator position accommodates installations where access or clearance above the duct is limited. This unit is appropriate for both new construction and retrofit zoning projects in residential and light commercial applications.

Key Features

Compatibility

Designed as an OEM-style replacement or new-install zone damper for rectangular duct systems requiring a 26-inch by 12-inch damper with a Belimo 3-wire actuator interface.

Installation Notes

Installation should be performed by a licensed HVAC technician familiar with forced-air zoning systems and low-voltage control wiring. Before servicing or installing, shut down the air handler and de-energize all associated control circuits. Secure the damper to the ductwork using sheet metal screws and seal all joints with approved duct tape or mastic sealant in accordance with local mechanical codes. Verify actuator wiring against the zone controller or panel specifications before restoring power.
