Io Hvac Controls MD-2608 Rectangular Zone Damper 26x8 in

Product Description

The IO HVAC CONTROLS MD-2608 is a rectangular two-position zone damper sized at 26 inches by 8 inches, equipped with a Belimo three-wire actuator. It is designed to control airflow within a zoned HVAC duct system by opening or closing to direct conditioned air where it is needed. The two-position actuator operates on a simple open/close command signal, making it compatible with standard zone control boards and thermostats. Weighing 9 pounds, the MD-2608 is built for straightforward field installation in residential and light commercial duct systems by licensed HVAC technicians.

This damper is intended for rectangular duct applications where zone control is required. The 26-inch by 8-inch blade size fits standard rectangular trunk or branch ducts of matching dimensions. The integrated Belimo three-wire actuator eliminates the need for a separate actuator purchase and simplifies wiring at the zone control panel. Typical installations include multi-zone forced-air systems in residential homes and small commercial buildings where individual room or area temperature control is required.

Installation Notes

Installation should be performed by a licensed HVAC technician. Shut down the air handler and de-energize the zone control panel before mounting or wiring the damper. The damper should be secured to the duct using sheet metal screws with an airtight connection to prevent bypass leakage. Follow low-voltage wiring practices and local mechanical codes when connecting the actuator leads to the zone control board.
