The R3G225-RN28-01 from EBM-Papst is a compact DC centrifugal fan with backward-curved blades, designed for demanding ventilation and cooling applications. The fan is powered by an M3G074-CF type EC motor operating at 24 V DC, delivering an impressive airflow of up to 1,275 m³/h at free flow. Thanks to the aerodynamic design of the RadiCal impeller, high performance is combined with low energy consumption.
The fan is ideal for applications requiring precise control and energy-efficient operation – for example, in industrial ventilation, refrigeration equipment, and air handling units. The 0–10 V DC or PWM control input makes speed regulation easy to integrate into existing systems.
- Airflow: up to 1,275 m³/h at free flow
- Supply voltage: 24 V DC (range 16–28 V DC)
- Power consumption: 205 W, rated current 8.5 A
- EC motor with soft start, tach output, and current limitation
- Control input 0–10 V DC / PWM, as well as overvoltage and polarity protection
- RadiCal impeller with 7 PA plastic blades, 225 mm
- Ball bearings and IP44 protection class
- Connection via AWG16 PVC cable with 4 conductors and wire end ferrules

| Voltage | 24V DC VAC |
| Motor frame | The fan is a freestanding centrifugal fan without a separate stand. The standard mounting position is shaft horizontal or rotor upwards; rotor downwards can be ordered on request. Fastening is done with screws with a maximum screw-in depth of 12–14 mm. An accessory inlet nozzle (part no. 96358-2-4013) is available but not included in the delivery. |
| Impeller | The fan impeller is a RadiCal impeller with backward-curved blades and a single-sided inlet opening, with a size designation of 225 mm. It has 7 blades made of PA plastic, and the rotor surface is painted black. At nominal voltage, an airflow of up to 1275 m³/h is achieved at free air flow. The fan impeller rotates clockwise when viewed towards the rotor. |
