The R4E280-AD08-25 from EBM Papst is an AC centrifugal fan with backward-curved blades, designed for demanding ventilation and air handling applications. The fan delivers an airflow of up to 1,425 m³/h and is powered by the M4E068-DF motor – a single-phase motor for 230 V AC at 50 or 60 Hz. The combination of high efficiency and robust construction makes it a reliable choice in industrial environments.
The fan is perfectly suited for air handling units and industrial ventilation where stable flow and long operating times are required.
