The R3G146-AK07-14 from EBM-Papst is a compact and powerful EC-motorized impeller, 146 mm in size, designed for blower and centrifugal fan applications. It is powered by a single-phase EC motor type M3G055-DF at 230 V AC and delivers an impressive airflow of 350 m³/h with a static pressure of 569 Pa. Thanks to hybrid bearing technology, it combines long service life with quiet and efficient operation.
The unit is perfectly suited for stationary ventilation and air handling systems where compact size, flexible mounting position, and precise control are important. Support for 0–10 V DC/PWM control signal and tach output makes it easy to integrate into modern control systems.
