The R3G175-RD53-08 from EBM-Papst is a compact and powerful EC centrifugal fan of the RadiCal type with backward-curved blades. It is powered by an electronically commutated motor and delivers an airflow of up to 870 m³/h – an excellent choice for demanding ventilation applications. Thanks to EC technology, high efficiency is combined with low energy consumption.
The fan is ideal for air handling units, cooling systems, and industrial ventilation where reliable continuous operation and a compact size are important. The optional mounting position makes installation flexible.

| Motor frame | The fan is a free-standing centrifugal fan, 175 mm in size, without a separate mounting frame. The mounting position is optional thanks to the ball bearing motor. An accessory in the form of an inlet ring (article number 09576-2-4013) is available but not included in the delivery. Screw fastening is permitted with a maximum fastening depth of 10 mm and 5 mm respectively, depending on the fastening point, according to the product drawing. |
| Casing | 175 mm, RadiCal centrifugal fan |
| Impeller | The fan impeller is a RadiCal impeller with backward-curved blades and a single inlet opening. It is made of PA plastic and has 7 blades. The rotor surface is thick-film passivated for corrosion protection. At nominal operating conditions (4720 rpm), the impeller delivers an airflow of up to 870 m³/h with a static pressure increase of up to approximately 700 Pa. The fan impeller has an open rotor design without condensate drainage holes. |
| Bearing type | ball bearing |
| IP class | IP54 |
| Motor protection | Electronic motor protection |
| Motor code | M3G055-CF |
| Rotation direction | clockwise, looking towards the rotor |
| Motor type | The motor is an EC motor (electronically commutated) of type M3G055-CF with single-phase supply at 230 V AC (200–240 V) and frequency 50/60 Hz. It has a power consumption of 166 W and a rated current of 1.4 A in nominal operating mode. The motor is equipped with ball bearings and has insulation class B. The protection class is I (requires protective earth connection by the customer), and the operating mode is S1 (continuous operation). Electronic motor protection function is included, including overvoltage protection, undervoltage protection, and thermal overload protection for electronics and motor. |
