The S4D450-AO14-02 from EBM-Papst is a robust axial fan with a protective grille, designed for demanding industrial ventilation applications. The fan is supplied in size 538 × 538 × 214 mm and is powered by a three-phase AC motor (M4D094-HA) for 400/480 V AC at 50/60 Hz. With an IP54 protection rating and ball bearings, it is built for long and reliable operation.
The fan is ideal for integration into units and duct systems where high airflow and robust construction are required. The sickle-shaped steel blades with a PP plastic surface contribute to efficient airflow control and low noise levels.
