The 3412NH from EBM-Papst is a compact DC axial fan with a wall ring, measuring 92 × 92 × 25 mm. The fan delivers an impressive airflow of 91 m³/h and is excellent as a spare part or in new installations where reliable cooling is required. Thanks to ball bearings and a robust plastic housing, it is built for long and stable operation.
The model is well-suited for electronics cooling, telecommunications equipment, and industrial applications where quiet and efficient air circulation is important. The optional mounting position makes it easy to integrate the fan into existing designs.

| Motor frame | The fan has dimensions of 92 × 92 × 25 mm and is mounted in a plastic housing. Mounting screws of type ISO 4762 M4 (degreased, without washer or extra support) are used. The maximum tightening torque during assembly is 40 Ncm in the corner with the cable and 60 Ncm in the other corners. The mounting position for 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 outwards over the struts. At a nominal speed of 3000 rpm, the fan impeller provides a maximum free airflow of 91 m³/h and a maximum static pressure of 47 Pa. |
| Bearing type | ball bearing |
| Rotation direction | counter-clockwise (viewed from the rotor) |
| Motor type | The motor is a DC motor with automatic restart in case of a locked rotor. It has built-in reverse polarity protection via a rectifier diode. Nominal voltage is 12 V DC with a voltage range of 8–15 V. Leakage current at nominal voltage is a maximum of 5 µA. The motor's protection class is Class III. |
