The 3412NGH is a compact DC fan from EBM-Papst in the DC axial fan category. It measures 92 × 92 × 25.4 mm and is equipped with a plastic wall ring housing and a double bearing for long and stable operation. The fan is ideal for electronics cooling, server equipment, and other applications where space is limited but cooling requirements are high.
With a voltage range of 8–15 V DC, the 3412NGH is flexible and easy to integrate into existing systems. The built-in reverse polarity protection and automatic restart in case of locked rotor make it robust and reliable.

| Motor frame | The fan has a square plastic casing with dimensions of 92 × 92 × 25.4 mm and a mass of 0.106 kg. Mounting is done with M4 screws (ISO 4762, degreased, without washer) through the mounting flanges. The maximum tightening torque is 40 Ncm for the corner where the cable is located and 60 Ncm for the other corners. |
| Casing | plastic, square |
| Impeller | The impeller is made of plastic and rotates counter-clockwise when viewed from the rotor side. The airflow is directed outwards over the struts (air outlet over struts). At a nominal speed of 3000 rpm, the impeller delivers a maximum free air flow of 91 m³/h and a maximum static pressure of 47 Pa. |
| Bearing type | plain bearing |
| Rotation direction | counter-clockwise |
| Motor type | The motor is a DC motor with a nominal voltage of 12 V and a voltage range of 8–15 V. It has built-in reverse polarity protection via a rectifier diode and automatic restart in case of a locked rotor. The motor's protection class is Class III. Power consumption at nominal voltage and free airflow is 208 mA with a power consumption of 2.5 W. |
