Io Hvac Controls MD-1410-BM Zone Damper 14x10 in Bottom Mount

Product Description

The IO HVAC CONTROLS MD-1410-BM is a rectangular 2-position zone damper designed for residential and light commercial HVAC zoning systems. Measuring 14 inches wide by 10 inches tall, this damper controls airflow to individual zones within a ducted forced-air system. It ships with a Belimo 3-wire actuator mounted to the bottom of the damper body, providing reliable open/close operation on a standard 24-volt control signal. Licensed HVAC technicians and zoning specialists are the typical installers for this type of equipment.

This damper is suited for rectangular supply or return duct applications where zone-by-zone airflow control is required. It fits into ducted systems as part of a multi-zone HVAC layout, typically controlled by a zone panel or thermostat system. The bottom-mount actuator orientation makes it a practical choice in installations where side or top access to the damper body is limited. The Belimo 3-wire actuator designation indicates spring-return or open/close operation compatible with standard low-voltage zoning controls.

Key Features

• Rectangular damper sized at 14 inches by 10 inches for direct duct installation
• 2-position operation (open/closed) for straightforward zone control
• Includes Belimo 3-wire actuator for reliable low-voltage actuation
• Bottom-mount actuator configuration for installations with restricted side or top access
• Designed for use in ducted forced-air residential and light commercial zoning applications

Compatibility

Designed as an OEM-style zone damper replacement or new-installation component for rectangular ducted forced-air HVAC zoning systems using standard low-voltage 3-wire actuator controls.

Installation Notes

Installation should be performed by a licensed HVAC technician familiar with ducted zoning systems. Disconnect power to the air handler and zone control panel before installing or wiring the actuator. The damper should be installed with proper sheet metal connections and sealed to prevent air bypass around the damper frame. Refer to the zoning panel manufacturer wiring diagram for correct actuator wire terminations, and verify polarity and control voltage before energizing the system.
