The W4S250-CA20-56 from EBM-Papst is a robust axial fan for single-phase AC, with a compact housing-shaped fan housing measuring 320×320×85 mm. The fan is powered by the M4S068-CF motor at 115 V AC at 60 Hz and delivers an impressive airflow of 1,030 m³/h. It is perfectly suited for ventilation systems, industrial units, and similar applications where high capacity and operational reliability are required.
With ball bearings and continuous operation (S1), the fan is built for demanding, long-term operation. The internal thermal overload protection and IP44 enclosure provide reliable protection in harsh environments.
