The 612F/2-638 from EBM-Papst is a compact DC tubeaxial fan in a 60 × 60 × 15 mm format, designed for reliable cooling and ventilation in space-constrained applications. The fan operates on 12 V DC and delivers an airflow of 27 m³/h with a low sound pressure of just 27 dB(A). With electronic commutation and built-in reverse polarity protection, it is easy to integrate into sensitive electronics.
Thanks to its optional mounting position and a 300 mm connection cable with a connector, the fan is ideal for control cabinets, medical equipment, network equipment, and other electronics where quiet and efficient air circulation is required.

|---|---|
| Airflow at 0 Pa | 27 m³/h |
| Speed | 3900 rpm |
| Power | 1 W |
| Voltage | 12 V DC VAC |
| Motor frame | The fan has a plastic casing with dimensions of 60 × 60 × 15 mm and a mass of 0.030 kg. It is mounted using M3 screws (ISO 4762) without washers or additional support. The maximum tightening torque varies depending on the mounting point: 50 Ncm at the cable outlet corners and 70 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 (air discharge over struts). At a nominal speed of 3,900 rpm, the fan delivers a maximum free air flow of 27 m³/h and a maximum static pressure of 29 Pa. |
| Bearing type | plain bearing |
| Rotation direction | counterclockwise |
| Motor type | The motor is a DC motor with electronic commutation and protection class III. It has built-in reverse polarity protection via a rectifier diode and automatic restart in case of a locked rotor. The rated voltage is 12 V DC with an allowed voltage range of 10.8–13.2 V. The nominal power consumption is 1 W and current consumption is 82 mA at free airflow. |
