The D3G146-LU09-31 from EBM-Papst is an EC-driven centrifugal fan with forward-curved blades, designed for demanding ventilation and air handling applications. This compact unit measures 215×202×272 mm and delivers an impressive airflow of 940 m³/h at 230 V AC. Thanks to the M3G055-CF EC motor, you get high efficiency, soft start, and easy speed control via 0–10 V DC or PWM signal.
The fan is ideal for air handling units, refrigeration systems, and industrial ventilation where energy efficiency and flexible control are crucial. Its optional mounting position makes installation easy in most configurations.
