The S4D400-AP12-04 from EBM-Papst is a robust axial fan with a protective grille, built for demanding industrial ventilation needs. The fan delivers an impressive airflow of up to 4,010 m³/h and is designed for three-phase AC operation with support for both 230 V (delta) and 400 V (star). With IP44 protection class and ball bearings, it is engineered for reliable, continuous operation in tough environments.
The fan is ideal for large ventilation units, industrial air treatment, and applications where high airflow and operational reliability are crucial. Its 400 mm square steel housing makes it easy to integrate into standardized duct systems.
