Johnson Controls M9220-GGC-3 Proportional Electric Spring Return Actuator W/2-Auxiliary switches 177 lb-In 24V

The Johnson Controls M9220-GGC-3 proportional electric spring return actuator is a complete package for air damper control in HVAC systems. It has a high-strength thermoplastic construction for durability and can be installed directly on the damper shafts. The higher the voltage, the greater the torque of the motor. The inherent spring-return mechanism of the damper also has the advantage of automatically closing (fail-safe) during power failure, guaranteeing shutdown during any abnormality. For enhanced functionality, it contains two auxiliary switches that provide electrical feedback on the position of the damper (open or closed). This real-time can be an input into building evaluations as well as in the building automation systems for managing air flow in buildings.
