The 3412N/2HH is a compact DC axial fan from EBM-Papst, measuring 92 × 92 × 25 mm. It operates on 12 V DC and is suitable for applications where reliable airflow and low power consumption are important. Thanks to ball bearings and reverse polarity protection, it is built for a long and reliable service life.
The fan is well-suited for cooling electronics, control cabinets, and industrial equipment. Its optional mounting position and 310 mm long cable make installation easy and flexible in most environments.

|---|---|
| Airflow at 0 Pa | 100 m³/h |
| Speed | 3250 rpm |
| Power | 2.9 W |
| Voltage | 12 V DC VAC |
| Motor frame | The casing is made of plastic and measures 92 × 92 × 25.4 mm. ISO 4762 M4 screws are used, degreased and without spacers. The maximum tightening torque varies depending on the mounting point: 40 Ncm at the cable outlet corner and 60 Ncm at the other corners. |
| 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. With free airflow and a nominal speed of 3250 rpm, the impeller delivers up to 100 m³/h and a maximum static pressure of 57 Pa. |
| Bearing type | ball bearing |
| Rotation direction | counterclockwise |
| Motor type | The motor is a DC motor with electronic control and reverse polarity protection via a rectifier diode. It has automatic restart upon locked rotor with a cycle of typically 0.2 s on and 1.1 s off. The motor lacks a dedicated electronic regulation function (no PWM or similar). The voltage range is 8–13.2 V with a nominal voltage of 12 V DC. |
