The R4E250-AB01-25 from EBM-Papst is an AC-powered centrifugal fan with backward-curved impellers, designed for demanding ventilation and air handling applications. With an airflow of up to 1070 m³/h and a robust galvanized sheet steel casing, it delivers reliable performance in continuous operation. The fan is excellently suited for air handling units, process cooling, and ventilation systems where stable and efficient air circulation is required.
Thanks to its flexible mounting position and compact design, the R4E250-AB01-25 is easy to integrate into existing systems. The M4E068-CF type motor is single-phase and operates on 230 V / 60 Hz, making it suitable for applications with North American mains frequency.
