1EASY INSTALLATION: Our electric damper actuator is user friendly and easy to install. Simply connect the damper shaft with the universal clamp and secure it with the anti rotation installation bar to prevent the actuator from rotating. 2ADJUSTABLE ROTATION ANGLE: The rotation angle can be easily adjusted through the mechanical limit switch, allowing for accurate control. 3MANUAL OPERATION OPTION: The actuator can be manually operated using a button to unlock or lock the gear transmission device. 4POWERFUL AND VERSATILE: The LFZ series electric damper driver is powered by imported DC brushless motor, providing a torsion range of 2Nm to 40Nm. It is suitable for angle stroke control in air and water systems, offering signal control options of 0(2)10V voltage or 0(4)20mA current with interchangeable feedback signals. 5WIDE APPLICATION: Our electric damper actuator can be directly applied to control the angle of ventilation systems and water systems. It is compatible with voltage and current signals, providing efficient and reliable control in various applications.
