The W4E450-WP01-30 from EBM-Papst is a powerful axial fan with a wall ring, built for demanding industrial ventilation tasks. The fan delivers an impressive airflow of up to 5,390 m³/h and is powered by a single-phase AC motor at 230 V at 50/60 Hz. With its compact dimensions of 688 × 548 × 232 mm, it fits where truly high capacity is needed.
The fan is excellent for industrial premises, ventilation units, and large air handling systems where reliable and continuous operation is a requirement. Ball bearings with low-temperature lubricant and an M4E074-GA type motor make it suitable even in cold operating environments.
