The R3G500-PB24-03 from EBM-Papst is a powerful EC centrifugal fan from the RadiPac series with backward-curved blades and single-sided air intake. The fan combines a three-phase EC motor type M3G150-IF with a 500 mm aluminum fan impeller for high efficiency and energy-efficient operation. It is excellent for large-scale ventilation and air handling systems where reliable performance and smart control are required.
Thanks to built-in RS-485 MODBUS-RTU communication, integrated PI controller, and configurable I/O, the R3G500-PB24-03 is well suited for modern building automation systems and industrial applications with high demands on control and operational monitoring.

| Airflow at 0 Pa | 8685 m³/h |
| Speed | 2000 rpm |
| Power | 3900 W |
| Frequency | 50/60 Hz |
| Voltage | 400V AC VAC |
| Motor frame | The fan is designed as a self-standing RadiPac centrifugal fan without a separate stand included in the standard delivery. The mounting position is shaft horizontal or rotor downward; mounting with rotor upward can be ordered on request. Condensate drain holes are located on the impeller side. An accessory inlet cone (64025-2-4013 with pressure tap, k-factor 281) is available as an option but not included in the standard delivery. Weight: 25.8 kg. |
| Casing | cast aluminum, the material of the electronics enclosure |
| Impeller | The fan impeller is made of sheet aluminum and has 5 backward-curved blades with single-sided air intake. The rotor surface is painted black. The fan impeller has a size of 500 mm and is designed for high efficiency with an optimal efficiency value of approximately 70.3%. The fan impeller rotates clockwise when viewed from the rotor and provides an airflow of up to approximately 15,810 m³/h at free air when operating at maximum load. |
| Bearing type | ball bearing |
| IP class | IP55 |
| Motor protection | thermal overload protection for electronics/motor |
| Motor code | M3G150-IF |
| Rotation direction | clockwise, looking towards the rotor |
| Motor type | The motor is type M3G150-IF, a three-phase EC motor (electronically commutated) designed for operation at 400 V AC (range 380–480 V AC) and 50/60 Hz. The rated power is 3900 W at 2000 rpm and the rated current is 6.0 A. The motor is equipped with passive power factor correction (PFC) via a low-capacitance DC link, as well as integrated soft start function and motor current limitation. The ingress protection rating is IP55 and the insulation class is F. The motor has built-in RS-485 MODBUS-RTU communication, configurable I/O, integrated PI controller, and LED indication for operating status. |
