The 612N/2H from EBM-Papst is a compact tubeaxial DC fan measuring 92 × 92 × 25.4 mm. It is designed for reliable operation at 12 V DC and delivers up to 91 m³/h at free air flow. With ball bearings and a robust plastic housing, it is built for long operating life in demanding environments.
The fan is ideal for cooling electronics, control cabinets, and embedded systems where quiet operation and a compact form factor are prioritized. The integrated alarm output (open collector) makes it easy to monitor the rotational speed in applications with reliability requirements.

|---|---|
| Airflow at 0 Pa | 91 m³/h |
| Speed | 3000 rpm |
| Power | 2.5 W |
| Voltage | 12 V DC VAC |
| Motor frame | The casing is made of plastic and measures 92 × 92 × 25.4 mm with a mass of 0.106 kg. ISO 4762 M4 mounting screws are used, degreased and without a washer. Maximum tightening torque varies depending on the mounting corner: 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 exits over the struts. At free airflow and 3000 rpm, a maximum airflow of 91 m³/h and a maximum static pressure of 47 Pa are delivered. |
| Bearing type | ball 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, as well as automatic restart upon locked rotor. The locked rotor current is approximately 640 mA at nominal voltage. The motor is equipped with an open collector type alarm output signal (active low = OK). |
