The 612NMLE from EBM-Papst is a compact DC axial fan with a flange, measuring 60 × 60 × 25 mm. It is ideal for electronic equipment, cooling units, and industrial systems where space is limited but cooling is critical. The fan operates on 12 V DC with a wide voltage range of 8–15 V, providing excellent flexibility in design and installation.
Thanks to its low sound pressure of just 21 dB(A), the 612NMLE is well-suited for noise-sensitive environments—such as medical equipment, network hardware, and office electronics.

| Motor frame | The fan has a square plastic casing measuring 60 × 60 × 25 mm and a mass of 0.066 kg. ISO 4762 – M3 mounting screws are used without washers or additional support. The mounting position for the shaft is optional. The maximum torque during assembly varies depending on the corner: 20 Ncm at the cable corner and 40 Ncm at the other corners. |
| Casing | plastic, square |
| Impeller | The fan impeller is made of plastic and rotates clockwise when viewed from the rotor side. Airflow is discharged over the struts. At a nominal speed of 3000 rpm and free air flow, a maximum flow rate of 23 m³/h and a maximum static pressure of 24 Pa are achieved. |
| Bearing type | ball bearing |
| Rotation direction | clockwise |
| Motor type | The motor is a DC motor with no specified motor designation. It has a voltage range of 8–15 V DC with a nominal voltage of 12 V DC. The motor is equipped with reverse polarity protection via a rectifier diode and automatic restart in case of a blocked rotor. The rated power at free airflow is 0.4 W and the rated current is 35 mA. |
