The 8312 from EBM-Papst is a compact DC axial fan with a wall ring, measuring 80 × 80 × 32 mm. The fan operates within a wide voltage range of 6–15 V DC and delivers an airflow of up to 52 m³/h. It is ideal as a reliable and quiet component in electronic equipment, cooling systems, and industrial applications.
With an estimated ball bearing life of 70,000 hours (L10) and automatic restart in case of a locked rotor, the 8312 is built for continuous operation in demanding environments. Optional mounting positions and an included 310 mm cable make installation easy and flexible.

| Motor frame | The fan has dimensions of 80 × 80 × 32 mm and weighs 170 grams. The casing is made of plastic. Mounting is done with ISO 4762 M4 screws, degreased and without a washer. The maximum tightening torque varies depending on the mounting point: 20 Ncm at the corners of the cable outlet and 30 Ncm at the other corners. |
| Casing | plastic, square |
| Impeller | The impeller is made of plastic and rotates clockwise when viewed from the rotor side. The airflow is directed over the struts (air outlet over struts). At a nominal speed of 3,300 rpm, the impeller provides a maximum free airflow of 52 m³/h and a maximum static pressure of 60 Pa. |
| Bearing type | ball bearing |
| Motor protection | automatic restart on locked rotor |
| Rotation direction | clockwise |
| Motor type | The motor is a DC motor with a nominal voltage of 12 V and a voltage range of 6–15 V. The power consumption is 2.6 W at nominal voltage and free air flow. The motor has reverse polarity protection via a rectifier diode and automatic restart in case of a locked rotor. The lifespan is estimated at 70,000 hours (L10) at 40 °C ambient temperature. |
