The 3412NG is a compact axial fan from EBM-Papst in the DC fans category. It measures 92 × 92 × 25 mm and is powered by a 12 V DC motor with a wide voltage range of 8–15 V. The fan is ideal where space is limited but reliable airflow is still required.
Thanks to its low sound pressure of 33 dB(A) and low power consumption of 2.2 W, the 3412NG is well-suited for electronics cooling, medical equipment, and embedded systems where quiet operation and energy efficiency are important.

Technical specifications
Datasheet (PDF) - download| Product attribute | Value |
|---|---|
| Airflow at 0 Pa | 82 m³/h |
| Speed | 2700 rpm |
| Power | 2.2 W |
| Voltage | 12 V DC VAC |
| Motor frame | The fan has a plastic housing with dimensions 92 × 92 × 25.4 mm and a mass of 0.106 kg. Mounting is done with ISO 4762 M4 screws, degreased and without a washer, over both mounting flanges. The motor shaft can be mounted in any position, and the specified torque for the screw corners varies between 40 and 60 Ncm depending on the position. |
| Casing | plastic, square |
| Impeller | The fan impeller is made of plastic and rotates counter-clockwise when viewed from the rotor side. The airflow exits over the struts (air outlet over struts). At nominal operating conditions (2700 rpm, free airflow), the fan impeller delivers a maximum airflow of 82 m³/h and a maximum static pressure of 39 Pa. |
| Bearing type | plain bearing |
| Rotation direction | counter-clockwise |
| Motor type | The motor is a DC motor with no specified motor designation, designed for 12 V DC nominal voltage with a voltage range of 8–15 V. Current consumption at nominal speed and free airflow is 185 mA with a power consumption of 2.2 W. The motor has reverse polarity protection via a rectifier diode and automatic restart in case of a blocked rotor. Protection class III applies to electrical safety. |
