The S4E250-BI02-72 from EBM-Papst is a robust AC axial fan, designed for demanding ventilation applications. The fan features a round steel casing with a protective guard grille and is powered by a single-phase 230 V AC motor with a power output of 42 W. With ball bearings and an IP44 rating, it is built for long and reliable operation.
The fan is ideal for air handling units, air treatment systems, and industrial ventilation where stable airflow and high operational reliability are required. The S-series sickle-shaped fan blades contribute to high efficiency and low noise levels.
