The 8315100161 from EBM-Papst is a compact DC axial fan with dimensions of 80 × 80 × 38 mm and an IP68 protection rating – built for demanding environments where moisture and dust are a factor. With an impressive airflow of 204 m³/h and a maximum static pressure of 1145 Pa, it delivers exceptional performance in a small form factor. The fan is powered by an electronically speed-controlled DC motor with a nominal voltage of 12 V.
Thanks to PWM control (2–5 kHz), the speed can be continuously adjusted between 0 and 100%, making the fan ideal for applications in industrial electronics, server cabinets, and other equipment where precise air cooling and a sealed design are required.

Technical specifications
Datasheet (PDF) - download| Product attribute | Value |
|---|---|
| Airflow at 0 Pa | 204 m³/h |
| Speed | 15,500 rpm |
| Power | 38 W |
| Voltage | 12 V DC VAC |
| Motor frame | The housing is square and made of plastic, with dimensions of 80 × 80 × 38 mm and a mass of 220 g. Mounting is done with degreased ISO 4762 M4 screws, without additional support or washer. The mounting position can be arbitrary in terms of the shaft's orientation. The maximum tightening torque varies between 50 Ncm (cable outlet corner) and 110 Ncm (other corners). |
| Casing | plastic, square |
| Impeller | The fan impeller is made of plastic and designed for axial flow with air discharge over the struts. At 100% PWM and free airflow, an airflow of 204 m³/h and a maximum static pressure of 1145 Pa are achieved. The optimal operating point is 145 m³/h at 510 Pa. The direction of rotation is counter-clockwise when viewed towards the rotor. |
| Bearing type | ball bearing |
| IP class | IP68 |
| Motor protection | automatic restart on locked rotor |
| Motor code | VWCF080KHFMS |
| 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 8–16 V. Power consumption at free airflow is up to 3200 mA at nominal voltage. The motor has reverse polarity protection via a P-channel FET and automatic restart upon locked rotor. Speed is controlled via a PWM signal (2–5 kHz) with 0–100% speed regulation capability. |
