The 8412N/2GHP from EBM-Papst is a compact DC axial fan with a flanged housing, measuring 80 × 80 × 25 mm, designed for electronic cooling and ventilation with a 12 V DC power supply. The fan delivers up to 78 m³/h of free air flow and maintains a low noise level of 37 dB(A). With PWM speed control and an open collector tachometer signal, it is well-suited for controllable cooling solutions.
The fan is suitable for control cabinets, embedded systems, and industrial electronics where a compact form factor and precise speed control are important. The optional mounting position provides great flexibility in design and installation.

|---|---|
| Airflow at 0 Pa | 78 m³/h |
| Speed | 3600 rpm |
| Power | 3 W |
| Voltage | 12 V DC VAC |
| Motor frame | The fan is flange-mounted at all four corners using ISO 4762 M4 screws (degreased, without washer, and without additional support). Maximum tightening torque varies by corner: 50 Ncm for the corner with the cable outlet and 70 Ncm for the other corners. The mounting position of the shaft is optional. |
| Casing | plastic, square |
| Impeller | The fan impeller is made of plastic and is housed in a plastic casing measuring 80 × 80 × 25.4 mm. With free air flow and 3600 rpm, the fan delivers up to 78 m³/h and a maximum static pressure of 58 Pa. The optimal operating point is 64 m³/h at 14 Pa. The airflow direction is air outlet over struts. |
| Bearing type | plain bearing |
| Rotation direction | counterclockwise |
| Motor type | The motor is a DC motor with electronic speed control via PWM signal (21–28 kHz, typically 25 kHz). The nominal voltage is 12 V DC with an allowable voltage range of 10.8–13.2 V. The motor has reverse polarity protection via a rectifier diode and automatic restart in case of a locked rotor. The motor shaft can be mounted horizontally, and the direction of rotation is counter-clockwise when viewed from the rotor. |
