The RER125-19/12N from EBM-Papst is a DC centrifugal fan with backward-curved blades, designed for compact installations where efficient airflow is required. The impeller measures 138 × 35 mm and delivers up to 105 m³/h at free air flow and a maximum static pressure of 125 Pa. The unit is supplied without a housing and is designed for mounting between two plates.
Thanks to its wide voltage range (7–15 V DC) and optional mounting position, the RER125-19/12N is well-suited for medical equipment, control cabinets, telecommunications, and other electronics where quiet and reliable cooling or ventilation is crucial.

|---|---|
| Airflow at 0 Pa | 105 m³/h |
| Speed | 2650 rpm |
| Power | 4.6 W |
| Voltage | 12 V DC VAC |
| Motor frame | The fan is supplied without a housing and is intended to be mounted between two plates. The test setup uses 220 × 220 mm steel plates with a 39 mm spacing between the bottom and top plates. The mounting position for the axis can be in any direction. The total mass of the fan is 0.310 kg. |
| Casing | mixed material, without chassis |
| Impeller | The fan impeller is a centrifugal fan (blower) without a casing, equipped with an inlet nozzle. Air is drawn in axially and blown out radially. The impeller is made of mixed material and has a diameter of 138 mm and a depth of 35 mm. At a nominal speed of 2,650 rpm, a maximum free air flow of 105 m³/h and a maximum static pressure of 125 Pa are achieved. |
| Bearing type | ball bearing |
| Rotation direction | clockwise |
| Motor type | The motor is a DC motor without a chassis and without an electronic control unit. It has built-in reverse polarity protection via a rectifier diode and automatic restart in case of a locked rotor. The voltage range is 7–15 V with a nominal voltage of 12 V. At nominal voltage and free airflow, the current consumption is 380 mA and the power consumption is 4.6 W. |
