The R4E250-AH01-05 from EBM-Papst is a motorized impeller system with backward-curved blades, designed for demanding ventilation and air handling applications. With a 250 mm PA plastic impeller and a 230 V single-phase AC motor, it delivers an impressive airflow of up to 800 m³/h. The fan is ideal for air handling units, air treatment units, and industrial ventilation where compact design and high performance are required.
Thanks to the backward-curved single inlet and the well-balanced 11-blade impeller, the R4E250-AH01-05 offers quiet and efficient operation. Flexible mounting options make it easy to integrate into existing systems.
