The 4312NNU from EBM-Papst is a compact axial fan with a wall ring for direct current, designed for demanding environments where high performance and robustness are required. Measuring 119 × 119 × 32 mm and with an IP68 rating, it can withstand moisture and dust – yet still delivers an impressive airflow of 187 m³/h. The fan is part of EBM-Papst's S-Panther series and is built for long and reliable operation.
Thanks to its wide voltage range of 6–15 V DC, the 4312NNU is suitable for a range of applications – from industrial machinery and medical equipment to marine installations where water and vibration place particularly high demands on the component.

|---|---|
| Airflow at 0 Pa | 187 m³/h |
| Speed | 2700 rpm |
| Power | 4.3 W |
| Voltage | 12 V DC VAC |
| Motor frame | The fan is to be mounted using ISO 4762 M4 screws, degreased and without washers or additional support. The maximum tightening torque for mounting across both mounting flanges is 80 Ncm in all corners. The mounting position for the shaft is optional. The fan's mass is 0.26 kg. |
| Casing | plastic, square |
| Impeller | The fan impeller is made of plastic and is mounted in an axial fan of type 4312 NNU with dimensions 119 × 119 × 32 mm. The airflow is directed over the struts (air outlet over struts), and at free air flow, a maximum flow of 187 m³/h and a maximum static pressure of 66 Pa are achieved at 2700 rpm. The direction of rotation is clockwise when viewed towards the rotor. |
| Bearing type | ball bearing |
| IP class | IP68 |
| Motor protection | automatic restart on locked rotor |
| Rotation direction | clockwise |
| Motor type | The motor is a DC motor without specified electronic function and with reverse polarity protection via a rectifier diode. It has automatic restart at locked rotor with a locked-rotor current of approximately 1400 mA. The motor is designed for a voltage range of 6–15 V with a nominal voltage of 12 V DC. The lifespan is up to 75,000 hours (L10) at 40 °C ambient temperature. |
