The 622/2N is a compact DC axial fan from EBM-Papst, measuring 60 × 60 × 25 mm. It operates on 12 V DC and is perfectly suited for applications where limited space and reliable cooling are crucial. The fan delivers up to 40 m³/h at free air flow and maintains a maximum static pressure of 88 Pa.
With ball bearings, automatic restart upon locked rotor, and reverse polarity protection, the 622/2N is a robust choice for industrial electronics, control cabinets, and medical equipment. Optional mounting positions provide great flexibility in design.

Datasheet (PDF) - download| Product attribute | Value |
|---|---|
| Airflow at 0 Pa | 40 m³/h |
| Speed | 6100 rpm |
| Power | 2.1 W |
| Voltage | 12 V DC VAC |
| Motor frame | The fan is mounted via mounting flanges with ISO 4762 M3 screws, degreased and without extra washers or brackets. The mounting torque is limited to 10 Ncm in the corner at the cable outlet and 20 Ncm in the other corners. The mounting position for the shaft is optional. The unit weighs 0.070 kg. |
| Casing | plastic, square |
| Impeller | The impeller is made of plastic and mounted in a square plastic casing with dimensions of 60 × 60 × 25 mm. The airflow is directed over the struts (air outlet over struts). At nominal operation and free airflow, the fan achieves a maximum flow of 40 m³/h and a maximum static pressure of 88 Pa. The impeller rotates clockwise when viewed from the rotor side. |
| Bearing type | ball bearing |
| Rotation direction | clockwise |
| Motor type | The motor is a DC motor with electronic control and reverse polarity protection via a rectifier diode. In the event of a locked rotor, automatic restart is activated with a cycle pattern of typically 0.2 s / 1.1 s. The motor has no additional electronic functions and is rated protection class III. The operating voltage range is 8–15 V DC with a nominal voltage of 12 V DC. |
