The 8315100473 from EBM-Papst is a compact axial DC fan with dimensions of 40 × 40 × 28 mm. It is powered by a 24 V DC motor with electronic speed control and delivers an impressive airflow of 24 m³/h at a maximum static pressure of 305 Pa. Thanks to its small size, it is ideally suited for compact designs where performance cannot be compromised.
The fan is well-suited for cooling electronics, control equipment, and industrial devices where reliable and quiet operation is a requirement. With ball bearings and automatic restart in case of locked rotor, it is built for a long service life and high operational reliability.

|---|---|
| Airflow at 0 Pa | 24 m³/h |
| Speed | 12,000 rpm |
| Power | 2.7 W |
| Voltage | 24V DC VAC |
| Motor frame | The fan has a square plastic housing with dimensions 40 × 40 × 28 mm and a mass of 48 g. Mounting is done with degreased ISO 4762 M3 screws, without additional bridging and without a washer. The maximum tightening torque for the mounting flanges is 30 Ncm in all corners. |
| Casing | plastic, square |
| Impeller | The fan impeller is made of plastic and is an axial fan impeller that provides airflow over the struts. With free air circulation and a nominal speed of 12,000 rpm, a maximum airflow of 24 m³/h and a maximum static pressure of 305 Pa are achieved. The optimal operating point is 18 m³/h at 97 Pa. |
| Bearing type | ball bearing |
| IP class | IP20 |
| Motor protection | automatic restart on locked rotor |
| Motor code | VWCE040KJDDS |
| Rotation direction | counter-clockwise (viewed towards the rotor) |
| Motor type | The motor is a DC motor with electronic speed control and reverse polarity protection via N-channel FET. It features automatic restart at locked rotor and a locked-rotor current of approximately 1200 mA at nominal voltage. The operating voltage range is 15–30 V DC with a nominal voltage of 24 V DC. The motor comes with a tachometer signal (open collector, type /2) for speed feedback. |
