The R2E180-AS77-05 from EBM Papst is a compact centrifugal fan with backward-curved blades, designed for demanding ventilation applications. The fan measures 180×180×87 mm and is powered by a single-phase AC motor at 230 V AC, 50/60 Hz. With an airflow of up to 555 m³/h and an IP44 rating, it is built for reliable operation in harsh environments.
The fan is ideal for air handling units, air conditioning systems, and industrial ventilation where a compact size and high performance are required. The single-inlet design and backward-curved PA plastic blades provide efficient air handling with low noise levels.
