The 3412NGLE from EBM-Papst is a compact axial fan for direct current with a wall ring, in the 92 × 92 × 25 mm format. It is equipped with a brushless DC motor and is suitable for voltages between 8 and 15 V DC, with 12 V as the nominal voltage. Thanks to its low sound pressure of only 24 dB(A), the fan is well-suited for applications where quiet operation is important, such as in electronics cabinets, medical equipment, and industrial automation.
With built-in reverse polarity protection and automatic restart upon locked rotor, the 3412NGLE is built for reliable, maintenance-free operation in demanding environments.

Datasheet (PDF) - download| Product attribute | Value |
|---|---|
| Airflow at 0 Pa | 58 m³/h |
| Speed | 1950 rpm |
| Power | 1.1 W |
| Voltage | 12 V DC VAC |
| Motor frame | The fan has a plastic casing measuring 92 × 92 × 25.4 mm and a mass of 0.106 kg. Mounting is done via mounting flanges with ISO 4762 M4 screws (degreased, without washer, and without additional support). The torque limit is 40 Ncm in the corner with the cable and 60 Ncm in the other corners. The mounting position for the motor shaft can be arbitrary. |
| 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 nominal voltage and free airflow, a maximum airflow of 58 m³/h and a maximum static pressure of 20 Pa are achieved. The optimal operating point is at 38 m³/h and 7 Pa. |
| Bearing type | plain bearing |
| Rotation direction | counter-clockwise |
| Motor type | The motor is a brushles DC motor designed for 12 V nominal voltage with a voltage range of 8–15 V. At nominal voltage and free airflow, the current consumption is 90 mA and the power consumption is 1.1 W. The motor has built-in reverse polarity protection via a rectifier diode and automatic restart in case of a locked rotor. The locked rotor current is approximately 220 mA at nominal voltage. |
