The R4E180-AS11-05 from EBM-Papst is a compact centrifugal fan with forward-curved blades, designed for demanding ventilation and air handling applications. The fan measures 180×180×125 mm and is powered by a single-phase 230 V AC motor with a frequency of 50/60 Hz. With an airflow of up to 965 m³/h, it delivers impressive performance in a small form factor.
Thanks to its optional mounting position and continuous operating mode (S1), the fan is perfectly suited for units, fan boxes, and industrial ventilation systems where reliability and flexibility are crucial.
