The 612F/2L-640 from EBM-Papst is a compact DC axial fan with a wall ring, designed for 12 V DC systems. Measuring 60 × 60 × 15 mm, the fan is ideal for applications where space is limited but reliable airflow is required. With a free air flow of 15.0 m³/h and a noise level of only 11 dB(A), it offers quiet and efficient cooling.
The fan is well-suited for electronics cabinets, medical equipment, and embedded systems where low noise levels and a shallow installation depth are crucial. Optional shaft position and pre-wired connection with a connector further simplify installation.

Datasheet (PDF) - download| Product attribute | Value |
|---|---|
| Airflow at 0 Pa | 15.0 m³/h |
| Speed | 2250 rpm |
| Power | 0.33 W |
| Voltage | 12 V DC VAC |
| Motor frame | The housing is square and made of plastic with dimensions of 60 × 60 × 15 mm. Mounting is done with M3 screws (ISO 4762, degreased, without washer). Maximum tightening torque varies depending on the mounting corner: 50 Ncm at the cable corner and 70 Ncm at the other corners. The shaft can be in any position. |
| Casing | plastic, square |
| Impeller | The fan wheel is made of plastic and rotates counter-clockwise when viewed from the rotor side. The airflow is discharged over the struts. At a nominal speed of 2250 rpm, a free airflow of 15.0 m³/h and a maximum static pressure of 9 Pa are delivered. |
| Bearing type | plain bearing |
| Motor protection | automatic restart on locked rotor |
| Rotation direction | counterclockwise |
| Motor type | The motor is a DC motor with a rated voltage of 12 V and a voltage range of 10.8–13.2 V. Current consumption at free airflow is nominally 27 mA. The motor has built-in reverse polarity protection via a diode and automatic restart in case of a locked rotor. Locked rotor current is approximately 36 mA at rated voltage. |
