Johnson Controls M9220-HGC-3 Electric Spring Return Damper Actuator W/2-Auxiliary Switch 177 in-lb 24V

The Johnson Controls M9220-HGC-3 Proportional Electric Spring Return Actuator with Zero and Span which is a well choice for air damper management in HVAC systems that need fail safe and custom operations. This makes it possible to achieve accurate control of the actuator to the control input so as to position the damper blade perfectly for optimum air flow within the HVAC system. Another benefit is the inclusion of a spring-return mechanism that causes the damper to close in case of power failure, thus ensuring the right shutdown in case of an incident. This real time data can be interfaced with building automation systems to improve the monitoring and control of airflow.
