The W3G400-ZN12-W1 from EBM-Papst is a powerful EC axial fan with a square panel housing, designed for demanding ventilation applications. The fan is powered by the M3G084-GF EC motor for three-phase operation and delivers an airflow of up to 4,525 m³/h at a static pressure increase of 454 Pa. Thanks to electronically commutated motor technology, you get high efficiency and lower energy consumption compared to traditional AC solutions.
The fan is ideal for ventilation units, refrigeration systems, and industrial air handling where robustness and reliable operation are crucial.
