The 3312NNU from EBM-Papst is a compact DC axial fan with a wall ring, designed for demanding environments where high reliability is essential. The fan measures 92 × 92 × 32 mm and is powered by a 12 V DC motor with a voltage range of 6–15 V. Thanks to its IP68 rating and stainless steel bearings, it easily withstands moisture, dust, and harsh operating conditions.
The fan is ideal for applications requiring robust construction and quiet operation – for example, in marine technology, industry, and medical equipment. The optional mounting position and the 310 mm long connecting cable make installation easy and flexible.

|---|---|
| Airflow at 0 Pa | 80 m³/h |
| Speed | 2650 rpm |
| Power | 1.6 W |
| Voltage | 12 V DC VAC |
| Motor frame | The casing is made of plastic, square-shaped, with dimensions of 92 × 92 × 32 mm. The fan is mounted using M4 screws (ISO 4762, degreased, without washer or extra support) in the mounting flanges. The maximum tightening torque is 80 Ncm in all corners. The mounting position is optional, with the shaft in any direction. |
| Casing | plastic, square |
| Impeller | The fan impeller is made of plastic and mounted on an axial fan with dimensions 92 × 92 × 32 mm. The airflow direction is out over the struts (air outlet over struts). At a nominal speed of 2650 rpm, the fan provides a maximum free airflow of 80 m³/h and a maximum static pressure of 49 Pa. The fan impeller rotates clockwise when viewed from the rotor. |
| Bearing type | stainless steel bearing |
| IP class | IP68 |
| Motor protection | automatic restart on locked rotor |
| Motor code | VWCE092PHGHS |
| Rotation direction | clockwise (viewed facing the rotor) |
| Motor type | The motor is an axial-type DC motor with a nominal voltage of 12 V and a voltage range of 6–15 V. At nominal voltage and free airflow, the power consumption is 1.6 W and the current consumption is 135 mA. The motor has built-in reverse polarity protection via a rectifier diode and automatic restart in case of a locked rotor. The protection class is III and the insulation resistance exceeds 10 MOhm. |
