The R4E225-AI01-10 from EBM-Papst is an AC centrifugal fan with a motorized impeller, belonging to the blowers and centrifugal fans category. With a 225 mm impeller and backward-curved blades, it delivers a maximum airflow of 450 m³/h at free flow. It is an excellent replacement part or component for demanding ventilation and air handling systems.
The fan is designed for single-phase 230 V AC operation and works at both 50 and 60 Hz. The optional mounting position and robust IP44 rating make it easy to integrate into air handling units, cooling systems, and industrial ventilation solutions.
