The 8300100865 from EBM-Papst is a compact axial DC fan with dimensions of 40 × 40 × 28 mm. It is designed for high-performance cooling in confined spaces and is powered by an electronically speed-controlled 12 V DC motor with PWM control and a tachometer output.
The fan is ideal for electronics cabinets, server equipment, and industrial apparatus where high static pressure and compact dimensions are crucial. The maximum static pressure of 1,030 Pa makes it particularly suitable for applications with high resistance in the airflow path.
- Voltage: 12 V DC (range 6–13.8 V)
- Airflow: max 45 m³/h at free air flow
- Max static pressure: 1,030 Pa
- Rotational speed: 22,000 rpm (100% PWM)
- Bearing type: ball bearing for long lifespan
- Protection class: IP20
- Locked rotor protection with automatic restart and reverse polarity protection
- Connection: 310 mm cable with 4 conductors (PWM + tach)

|---|---|
| Airflow at 0 Pa | 45 m³/h |
| Speed | 22,000 rpm |
| Power | 11W |
| Voltage | 12 V DC VAC |
| Motor frame | The fan measures 40 × 40 × 28 mm and weighs 48 g. The housing is made of plastic. Mounting is done with ISO 4762 M3 screws (degreased, without spacer, and without washer) with a maximum tightening torque of 30 Ncm for all corners. The mounting position of the shaft can be arbitrary. |
| Casing | plastic, square |
| Impeller | The impeller is made of plastic and is of axial type with airflow direction outwards over the struts. The fan delivers a maximum free airflow of 45 m³/h and a maximum static pressure of 1,030 Pa at 22,000 rpm. The optimal operating point is 31 m³/h at 400 Pa. The impeller rotates counter-clockwise when viewed towards the rotor. |
| Bearing type | ball bearing |
| IP class | IP20 |
| Motor protection | locked rotor protection with automatic restart |
| Motor code | VWCE040KHDFS |
| Rotation direction | counter-clockwise (viewed from the rotor) |
| Motor type | The motor is an electronically speed-controlled DC motor with a nominal voltage of 12 V and a voltage range of 6–13.8 V. In free air flow and at 100% PWM, the motor achieves 22,000 rpm with a power consumption of up to 11 W. The motor is equipped with reverse polarity protection via N-channel FET, as well as locked rotor protection with automatic restart. The protection class is III and the enclosure rating is IP20. |
