Description
The Honeywell MS4105A1130/U 2-Position Direct Coupled S/R Damper Actuator is a spring-return actuator designed to operate air dampers between two positions. It drives the connected damper to control airflow and returns it to its normal position when required by the control sequence. In HVAC systems, it is used with air-handling and ventilation equipment where dependable damper positioning is needed. The actuator connects directly to the damper shaft allowing the motor movement to be transmitted to the damper using a separate linkage. Its operation supports controlled airflow and proper positioning during equipment startup shutdown and normal ventilation cycles.
