The W4D250-CA04-01 from EBM-Papst is a robust AC axial fan with IP44 rating, suitable for demanding industrial ventilation applications. The fan delivers an impressive airflow of 890 m³/h at 1,420 rpm and is powered by a 4-pole AC motor (M4D068-CF) for 230/400 V and 50 Hz. No external capacitor is required, simplifying installation.
The fan is ideal for units, ventilation systems, and process equipment where reliable air circulation and durable construction are crucial. The black painted sheet metal housing with a round shape makes it easy to integrate into existing systems.
