Description
The Ruskin FSTF120-RUS Electric On/Off Spring Return Actuator is designed to provide accurate control of airflow together with consistent torque for HVAC dampers. It has a spring-return mechanism that allows it to return to a predetermined position in case of a power failure. It is operated by 120 V AC and has a torque of 18 in-lb, power of 2W and holds power of 1.5W and has a maximum rotation angle of 95°. Suited for direct coupling to 1/2” shafts, it operates in the temperature range of 0°C to 50°C and relative humidity of 5% to 95%. Especially useful when used in HVAC systems to regulate the flow of air in dampers and vents.
