The 8315100474 from EBM-Papst is a compact DC axial fan measuring 40 × 40 × 28 mm. The fan delivers an impressive airflow of 24 m³/h and a maximum static pressure of 305 Pa at 12,000 rpm – all in a small package weighing only 48 grams. It is ideal for dense electronic cabinets, industrial equipment, and cooling solutions where space is limited.
Thanks to the built-in locked rotor protection with automatic restart and reverse polarity protection via N-channel FET, the fan is durable and reliable even in demanding environments. The mounting position is completely flexible, simplifying integration into various designs.

|---|---|
| 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 measuring 40 × 40 × 28 mm and weighs 48 g. Mounting is done with ISO 4762 M3 screws without washers and without extra support, with a maximum tightening torque of 30 Ncm in all corners. The mounting position is optional with the shaft in any direction. |
| Casing | plastic, square |
| Impeller | The impeller is made of plastic and rotates counter-clockwise when viewed from the rotor side. It provides a maximum free air flow of 24 m³/h and a maximum static pressure of 305 Pa at 12,000 rpm. The airflow direction is outward over the struts (air outlet over struts). The optimal operating point is 18 m³/h at 97 Pa. |
| Bearing type | ball bearing |
| IP class | IP20 |
| Motor protection | Locked rotor protection with auto-restart |
| Motor code | VWCE040KJDDS |
| Rotation direction | counter-clockwise (viewed from the rotor) |
| Motor type | The motor is a DC motor with speed control and reverse polarity protection via an N-channel FET. It has built-in locked rotor protection with automatic restart. The rated voltage is 24 V DC with an allowed voltage range of 15–30 V DC. Power consumption with free airflow and nominal voltage is 2.7 W. The motor lacks an internal fuse but has extended downtime protection after repeated start attempts. |
