Description
The Honeywell MS8120F1200/U 2-Position Spring Return Damper Actuator 24 VAC is designed to control the opening and closing of dampers used in ventilation and air distribution equipment. This actuator operates with two-position operates, allowing connected dampers to move between fully open and fully closed positions based on control signals from automation systems. Commonly installed in commercial HVAC applications, the unit supports regulating airflow through duct systems, rooftop units and air handlers to support balanced indoor air circulation. The spring return mechanism automatically returns the damper to its designated secure position during power loss, supporting controlled airflow management and system protection.
