The Belimo NMX120-3 On/Off Floating NSR Damper Actuator 100–240 VAC is an electric part to control damper positioning for regulated airflow in ventilation equipment. It delivers reliable motion control to support HVAC systems enabling accurate opening and closing of dampers within air distribution networks. Operating on power with an on/off and floating control operator, the actuator ensures responsive positioning for airflow management. Mounted on dampers in ductwork or air handling units, it supports maintaining balanced air distribution, supports system efficiency, and contributes to stable environmental control.
