The W4D250-CA36-01 from EBM-Papst is a robust axial fan with a wall ring, designed for demanding industrial ventilation applications. The fan measures 320×320×93 mm and is powered by a three-phase AC motor (M4D068-CF) that can be delta-connected at 230 V or star-connected at 400 V. With an airflow of up to 920 m³/h at 50 Hz, it provides reliable and efficient air circulation.
The fan is excellently suited for air handling units, industrial ventilation, and heat recovery systems where durable construction and stable airflow are crucial. The galvanized sheet steel casing with black plastic coating (RAL9005) and included protective grille make it ready for direct installation.
