The R3G310-PV69-03 from EBM-Papst is a powerful EC centrifugal fan with backward-curved blades, designed for demanding ventilation and air handling applications. The fan delivers an airflow of up to 4,020 m³/h and is powered by the three-phase EC motor M3G112-GA with a rated voltage of 400 V AC. The housing is cast in aluminum, and the IP55 protection class makes it suitable for harsh environments.
The fan is excellently suited for industrial ventilation systems, air handling units, and process ventilation where high efficiency and operational reliability are crucial. Thanks to EC technology and the energy-efficient RadiPac impeller, operating costs are kept low even during continuous operation (S1).
