Io Hvac Controls MD-3014-BM Zone Damper 30x14 Bottom Mount

Product Description

The IO HVAC CONTROLS MD-3014-BM is a rectangular two-position zone damper sized at 30 inches wide by 14 inches tall, fitted with a Belimo three-wire actuator mounted at the bottom of the frame. Two-position zone dampers control airflow by switching between fully open and fully closed, making them a standard component in zoned forced-air HVAC systems. The Belimo actuator provides reliable, repeatable positioning and is driven by a standard three-wire control signal. This damper is installed by licensed HVAC technicians during new construction zoning layouts or retrofit zone control upgrades.

The MD-3014-BM is suited for rectangular duct applications in residential and light commercial forced-air systems where zone control is required. Its 30-by-14-inch blade size fits a corresponding duct opening of that dimension. The bottom-mount actuator orientation makes it a fit for installations where top or side clearance is limited. HVAC techs typically deploy this damper as part of a multi-zone control system paired with a zone control board and individual thermostats.

Key Features

• 30 inches by 14 inches rectangular blade size for direct duct installation
• Two-position operation: fully open or fully closed for straightforward zone control
• Factory-mounted Belimo three-wire actuator for dependable actuation
• Bottom-mount actuator orientation accommodates restricted overhead or side clearance
• Designed for use in multi-zone forced-air HVAC systems

Compatibility

Designed as an OEM-style zone damper for rectangular duct systems requiring a 30-by-14-inch two-position damper with a Belimo three-wire actuator interface.

Installation Notes

Installation should be performed by a licensed HVAC technician in accordance with local mechanical codes and the system manufacturer guidelines. Shut down the air handling unit and de-energize the zone control board before installing or wiring the damper. Verify actuator wiring matches the three-wire control scheme of the zone board before energizing. Ensure the damper frame is square to the duct opening and sealed per applicable mechanical code requirements to prevent bypass leakage.
