The 8315100135 from EBM-Papst is a compact and powerful DC axial fan with dimensions of 80 × 80 × 38 mm. It is designed for demanding applications where high airflow and high static pressure are required in a small format. With a rated voltage of 48 V DC and PWM speed control, it is ideal for modern control systems.
The fan is well suited for cooling electronics, server cabinets, and industrial equipment where precision control and compact dimensions are important.

Datasheet (PDF) - download| Product attribute | Value |
|---|---|
| Airflow at 0 Pa | 220 m³/h |
| Speed | 16,500 rpm |
| Power | 48 W |
| Voltage | 48 V DC VAC |
| Motor frame | The fan measures 80 × 80 × 38 mm and weighs 220 g. The housing is made of plastic. Mounting is done with degreased ISO 4762 M4 screws, without additional support or washer. The mounting torque is 50 Ncm in the cable outlet corner and 110 Ncm in the other corners. |
| Casing | plastic, square |
| Impeller | The fan impeller is made of plastic and rotates counter-clockwise when viewed from the rotor side. The airflow direction is outward over the struts. With free airflow and 16,500 rpm, a maximum airflow of 220 m³/h and a maximum static pressure of 1,160 Pa are achieved. The optimal operating point is 155 m³/h at 650 Pa. |
| Bearing type | ball bearing |
| Rotation direction | counter-clockwise |
| Motor type | The motor is a DC motor with electronic speed control via a PWM signal (1–10 kHz, typically 2 kHz). The rated voltage is 48 V DC with an allowed voltage range of 36–60 V. The motor has built-in reverse polarity protection via a rectifier diode and automatic restart in case of a locked rotor. Locked rotor current at rated voltage is approximately 200 mA and starting current is approximately 4,000 mA. |
