The 512F/2-531 from EBM-Papst is a compact DC axial fan with a wall ring, measuring 50×50×15 mm, designed for cooling and ventilation in electronics and industrial equipment. It operates on 12 V DC and delivers an airflow of up to 18.5 m³/h with a low sound pressure of just 28 dB(A).
Thanks to its small size and flexible mounting position, the fan is ideal for control cabinets, built-in systems, and other electronics where space is limited but there is a real need for cooling.

|---|---|
| Airflow at 0 Pa | 18.5 m³/h |
| Speed | 5000 rpm |
| Power | 1 W |
| Voltage | 12 V DC VAC |
| Motor frame | The fan has a square plastic casing measuring 50×50×15 mm and weighing 0.025 kg. Mounting is done with M3 screws (ISO 4762) without a washer or extra support. The tightening torque is a maximum of 50 Ncm for the cable corner flange and 60 Ncm for the other corners. |
| Casing | plastic, square |
| Impeller | The fan impeller is made of plastic and has a diameter adapted for the 50x50 mm format. Airflow occurs out over the struts (air outlet over struts). At a nominal speed of 5000 rpm, the fan provides a maximum free airflow of 18.5 m³/h and a maximum static pressure of 38 Pa. |
| Bearing type | plain bearing |
| Motor protection | impedance protected against locked rotor |
| Rotation direction | counter-clockwise |
| Motor type | The motor is a DC motor with a nominal voltage of 12 V and a voltage range of 10.8–13.2 V. The power consumption is nominally 1 W at free airflow. The motor is impedance-protected at locked rotor and has reverse polarity protection via a rectifier diode. The direction of rotation is counter-clockwise when viewed from the rotor. |
