| Motor frame | The fan has a plastic housing with dimensions of 92 × 92 × 25.4 mm and a mass of 0.106 kg. ISO 4762 M4 mounting screws are used, degreased and without washers. The maximum tightening torque is 40 Ncm for the corner where the cable exits and 60 Ncm for the other corners. The mounting position for the shaft is arbitrary. |
| Casing | plastic, square |
| Impeller | The fan impeller is made of plastic and rotates counter-clockwise when viewed from the rotor side. The airflow is directed outwards over the struts. At a nominal speed of 3,000 rpm, the fan impeller delivers a maximum free air flow of 91 m³/h and a maximum static pressure of 47 Pa. The optimal operating point is 70 m³/h at 13 Pa. |
| Bearing type | ball bearing |
| Rotation direction | anticlockwise |
| Motor type | The motor is a DC motor with a nominal voltage of 12 V and a voltage range of 8–15 V. Power consumption at free air flow is 2.5 W and current consumption is 208 mA at nominal voltage. The motor has automatic restart at locked rotor and is equipped with reverse polarity protection via a rectifier diode. The bearing type is ball bearing with an L10 lifetime of 70,000 hours at 40 °C. |
