The 8315100138 from EBM-Papst is a compact and powerful DC axial fan measuring 80 × 80 × 38 mm. The fan operates on 48 V DC and delivers an impressive airflow of up to 178 m³/h – an excellent choice when high performance is required in a small form factor. With PWM control and a tacho output, it is perfect for systems with precision requirements for speed regulation.
The fan is well-suited for demanding cooling applications in industrial electronics, server cabinets, and power electronics where high static pressure and reliable operation are crucial.
- Voltage: 48 V DC (range 36–60 V)

|---|---|
| Airflow at 0 Pa | 178 m³/h |
| Speed | 13,200 rpm |
| Power | 25W |
| Voltage | 48 V DC VAC |
| Motor frame | The fan has a plastic chassis measuring 80 × 80 × 38 mm and weighing 220 g. Mounting is done via through-holes in all four corners with ISO 4762 M4 screws (degreased, without washer). The torque is limited to 50 Ncm in the cable outlet corner and 110 Ncm in the other corners. The mounting position on the axis is optional. |
| Casing | plastic, square |
| Impeller | The fan impeller is made of plastic and rotates counter-clockwise when viewed from the rotor side. The airflow is directed over the struts (air outlet over struts). At free airflow, a maximum flow of 178 m³/h and a maximum static pressure of 740 Pa are achieved. The optimal operating point is 125 m³/h at 410 Pa. |
| Bearing type | ball bearing |
| Motor protection | automatic restart on locked rotor |
| Rotation direction | counter-clockwise |
| Motor type | The motor is a DC motor with PWM control and a nominal voltage range of 36–60 V, with a nominal voltage of 48 V. It has reverse polarity protection via a rectifier diode and automatic restart in case of a locked rotor. The motor is speed-controlled via a PWM signal (1–10 kHz, typically 2 kHz) and provides an open collector tachometer output (/2). The starting current consumption is 2,300 mA. |
