The G3G140-AW21-12 from EBM-Papst is a compact EC centrifugal fan with a 140 mm round housing, designed for efficient and quiet air circulation. The fan is powered by an electronically commutated motor of type M3G055-CF and delivers an airflow of up to 300 m³/h at 2,370 rpm. Thanks to EC technology, it offers excellent energy efficiency and easy speed control via 0–10 V DC or PWM signal.
The fan is ideal for ventilation units, cooling systems, and air handling equipment where variable airflow and precise control are important. The optional mounting position and flange-mounted housing make installation easy in most applications.
