Io Hvac Controls MD-2406 Rectangular Zone Damper 24x6 in

Product Description

The IO HVAC CONTROLS MD-2406 is a rectangular 2-position zone damper sized at 24 inches by 6 inches, designed for zoned HVAC duct systems where precise airflow control is required. It ships with a Belimo 3-wire actuator, which handles both open and closed positioning on demand from a zone control board or thermostat. This damper controls conditioned air delivery to individual zones in residential or light commercial forced-air systems. Licensed HVAC technicians typically handle installation as part of a multi-zone retrofit or new construction build-out. The unit weighs 7 pounds and fits standard rectangular ductwork of the matching nominal size.

The MD-2406 is suited for rectangular supply or return duct branches in forced-air zoning applications. The 2-position operation makes it compatible with standard zone control panels that switch the actuator between fully open and fully closed states. Typical installations include residential multi-zone systems, small commercial HVAC builds, and retrofit zoning projects where balancing airflow between areas is the primary goal. The included Belimo 3-wire actuator eliminates the need to source a separate actuator, simplifying procurement and installation.

Key Features

• 24-inch by 6-inch rectangular form factor fits standard duct openings of the same nominal size
• 2-position operation provides fully open and fully closed airflow control
• Includes Belimo 3-wire actuator for reliable, field-proven actuation
• Compatible with standard zone control boards that output a 3-wire actuator signal
• 7-pound unit weight suitable for overhead or inline duct mounting

Compatibility

Designed as an OEM-style zone damper for rectangular duct zoning systems using a 3-wire actuator control signal. Verify duct opening dimensions and zone control panel actuator wiring type before ordering.

Installation Notes

Installation should be performed by a licensed HVAC technician familiar with forced-air zoning systems. Shut down the air handler and disable the zone control panel before mounting or wiring the damper. Secure the damper to the duct with sheet metal screws and verify the actuator rotates freely through its full travel before restoring power. Follow local mechanical codes and manufacturer wiring diagrams when connecting the 3-wire actuator leads to the zone control board.
