Electric damper actuator LFZ05

motorizedrotarypart-turn

Product overview
The LFZ05 damper actuator is a direct-coupled unit driven by a brushless motor, designed for reliable control of dampers in HVAC and mechanical ventilation systems. It supports multiple control modes (On/Off, 2-point, 3-point, 0(2)-10 VDC, 0(4)-20 mA, RS485) and offers low noise, long service life and easy on-site wiring with a terminal box and waterproof cable gland.
