Resideo MARD-14 Round Modulating Automatic Damper 14"

The Resideo MARD-14 Round Modulating Automatic Damper is an essentialaccessory in HVAC systems to control and modulate the airflow in residential or commercial ducting. This 14" diameter damper is constructed out of galvanized steel, which will provide the unit with a long service life. This damper employs modulating spring-return actuation to adjust the position of the damper and hence the airflow in response to a thermostat or control system. This ensures the highest levels of comfort can be maintained because heating or cooling is spread evenly through the building and delivered to the areas where it is most needed.
