The R3G400-RJ75-01 from EBM-Papst is a high-performance EC centrifugal fan with backward-curved RadiCal blades, designed for demanding industrial ventilation applications. With an airflow of 4,090 m³/h and IP55 protection class, it delivers reliable performance even in harsh environments. The integrated EC motor M3G112-EA enables energy-efficient and quiet operation with a sound pressure level of 68 dB(A).
The fan is ideal for air handling units, process ventilation, and heat recovery systems where robust construction and smart motor control are crucial. The built-in frequency converter with PID controller, soft start, and RS-485 MODBUS-RTU communication makes it easy to integrate into modern control systems.

| Motor frame | The fan weighs 8.7 kg and is designed for mounting with the shaft horizontally or with the rotor downwards; mounting with the rotor upwards is possible on request. Condensate drainage is located on the rotor side. Accessories in the form of an inlet cone (article number 54476-2-4013) are not included in the delivery but can be ordered separately. The maximum screw length for mounting is 16 mm. |
| Casing | die-cast aluminium, material of the electronics housing |
| Impeller | The impeller is of the RadiCal type with backward-curved blades and single inlet, with a size of 400 mm. It is made of PP plastic and has 6 blades. The rotor surface is black painted. The impeller rotates clockwise when viewed towards the rotor and provides an airflow of 4090 m³/h at a static pressure increase of 676 Pa at rated operation. |
| Bearing type | ball bearing |
| IP class | IP55 |
| Motor protection | Thermal overload protection (TOP), internally connected |
| Motor code | M3G112-EA |
| Rotation direction | clockwise, looking towards the rotor |
| Motor type | The motor is an EC motor (electronically commutated) of type M3G112-EA, designed for three-phase operation (3~) with a rated voltage of 400 V AC (range 380–480 V AC). The motor has insulation class F and environmental protection class H1. Motor protection is provided by an internal thermal overload protector (TOP). The motor is equipped with ball bearings and operating mode S1 (continuous duty). The integrated frequency inverter offers functions such as soft start, PID controller, motor current limiting, phase failure detection, and communication via RS-485 MODBUS-RTU. |
