|---|---|
| Airflow at 0 Pa | 238 m³/h |
| Speed | 11,000 rpm |
| Power | 31 W |
| Voltage | 12 V DC VAC |
| Motor frame | The fan has a square plastic casing measuring 92 × 92 × 38 mm and weighs 280 g. Mounting is done with M4 screws (ISO 4762) without a washer or extra support, with a maximum tightening torque of 30 Ncm in all corners. The cable is located in one of the corners of the casing. |
| Casing | plastic, square |
| Impeller | The fan impeller is made of plastic and designed for axial flow with air discharge over the struts. At a maximum speed of 11,000 rpm, the fan delivers a maximum free air flow of 238 m³/h and a maximum static pressure of 645 Pa. The optimal operating point is 170 m³/h at 300 Pa. |
| Bearing type | ball bearing |
| Motor protection | locked rotor protection with automatic restart |
| Rotation direction | clockwise (viewed facing the rotor) |
| Motor type | The motor is a DC motor with speed control and reverse polarity protection via a rectifier diode. The locked rotor protection activates automatic restart with an on/off cycle of typically 0.5 s / 10.0 s. Nominal voltage is 12 V DC with an allowed voltage range of 6–13.8 V. In free airflow and at nominal voltage, the motor consumes 31 W with a current of 2,600 mA. |
