Io Hvac Controls MD-1406-BM Rectangular Zone Damper 14x6 in

Product Description

The IO HVAC CONTROLS MD-1406-BM is a rectangular 2-position zone damper sized at 14 inches wide by 6 inches tall, designed for ducted HVAC zoning systems. It ships with a Belimo 3-wire actuator mounted on the bottom of the damper body, providing reliable open/close control in low-voltage zoning applications. At 6 pounds, the unit is manageable for single-technician installation in standard residential or light commercial ductwork. The Belimo actuator is a recognized name in HVAC controls, offering consistent torque and long service life in 2-position damper duty.

This damper is intended for rectangular duct zoning installations where a dedicated actuated damper controls airflow to a single zone. Typical applications include residential forced-air systems with zone control panels, light commercial VAV-style zoning, and new construction or retrofit duct zoning projects. The bottom-mount actuator configuration suits installations where side-mount access is restricted. HVAC technicians and sheet metal contractors are the primary installers for this product.

Installation Notes

Installation should be performed by a licensed HVAC technician or qualified sheet metal contractor. Shut down the air handling system and de-energize the zone control panel before wiring or mounting the damper. Secure the damper body to the duct using sheet metal screws and seal edges with mastic or foil tape per local mechanical code requirements. Refer to the Belimo actuator wiring diagram and the zone control panel documentation for low-voltage control wiring connections.
