The RL48-19/12ML from EBM-Papst is a compact DC centrifugal fan with forward-curved blades in a 76 × 76 × 27 mm format. It is designed for applications where space is limited but reliable airflow is still required. With ball bearings and a robust sheet metal housing, it is built for long and reliable operation.
The fan is ideal for electronics cabinets, medical technology equipment, and embedded systems where efficient radial airflow in a compact format is crucial. Its optional mounting position and short flange-mounted design simplify integration into existing systems.

|---|---|
| Airflow at 0 Pa | 21 m³/h |
| Speed | 3500 rpm |
| Power | 2.9 W |
| Voltage | 12 V DC VAC |
| Motor frame | The fan has a plastic housing with dimensions 76 × 76 × 27 mm and a mass of 0.075 kg. Mounting is done via a flange in both mounting corners with ISO 4762 M4 screws (degreased, without additional support or washer). The mounting position for the shaft can be arbitrary (optional). |
| Casing | plastic |
| Impeller | The fan impeller is made of plastic and rotates counter-clockwise when viewed from the rotor side. Air is drawn in axially and blown out radially, which is typical for a centrifugal fan (blower). At a nominal speed of 3,500 rpm and free airflow, the fan impeller provides a maximum airflow of 21 m³/h and a maximum static pressure of 98 Pa. |
| Bearing type | ball bearing |
| Rotation direction | counter-clockwise |
| Motor type | The motor is a DC motor without a specified electronic function and has built-in reverse polarity protection via a rectifier diode. It has automatic restart upon locked rotor with a typical on/off pattern of 0.16 s / 1.0 s. The rated voltage is 12 V DC with a voltage range of 8–15 V. Protection class III. |
