Electronic VAV Flow Controller Actuator • Primarily for use with variable air volume terminal units

Specifications: • Output torque: 45 +/- 10 in./Lb. (5 +/- 1 Nm) • Velocity range: 0 to 3,000 fpm (15.24 m/s) • Stroke time: 18° per minute • Angular rotation: selectable for 45°, 60° or 100° WARNING: Cancer and Reproductive Harm - www.P65Warnings.ca.gov

• Cooling and heating air flow is sensed by a temperature compensation hot-wire anemometer (sensor not included) • Actuator section provides a magnetic clutch which allows the actuator to be stalled at either end of stroke eliminating the requirement for mechanical stops or end switches
