The R3G630-FB32-03 from EBM-Papst is a powerful EC centrifugal fan with backward-curved blades, designed for demanding industrial ventilation applications. The fan combines the advanced RadiCal impeller with an integrated M3G150-IF EC motor, providing high efficiency and low energy consumption. With an airflow of 12,685 m³/h and IP55 protection, it is ideally suited for harsh operating environments.
The fan targets installers and OEMs in air handling, industrial ventilation, and process cooling where precise control and operational reliability are crucial. The integrated frequency converter with PID controller and RS-485 MODBUS-RTU makes it easy to integrate into modern automation systems.

| Motor frame | The fan is mounted with the shaft horizontally or with the rotor downwards as standard positions; mounting with the rotor upwards can be ordered upon request. Condensate drainage holes are located on the rotor side. For mounting, screws with a maximum insertion depth of 20 mm are used, and the tightening torque for the cable gland is 4 ± 0.6 Nm. The accessory inlet ring (article number 63355-2-4013) with a pressure tap is not included in the delivery but can be ordered separately. |
| Casing | cast aluminum, electronics enclosure housing |
| Impeller | The impeller is a backward-curved, single-inlet RadiCal impeller with a diameter of 630 mm. It is made of PP plastic and is painted black on the rotor surface. The impeller has 6 blades and rotates clockwise when viewed from the rotor. At nominal operating conditions, the impeller delivers an airflow of 12685 m³/h at a static pressure rise of 711 Pa. |
