The W4D400-DP12-41 from EBM-Papst is a robust axial fan with a wall ring, designed for demanding industrial ventilation. The fan is powered by a three-phase AC motor (M4D074-EI) in a star connection and is suitable for 380 V / 50 Hz or 480 V / 60 Hz power supply. With a maximum airflow of 4,010 m³/h and a compact design in galvanized sheet metal, it is built for long-term, reliable operation.
The fan is ideal for industrial ventilation systems, air handling units, and process cooling where high airflow and operational reliability are crucial.
