|---|---|
| Airflow at 0 Pa | 91 m³/h |
| Speed | 3050 rpm |
| Power | 2.1 W |
| Voltage | 12 V DC VAC |
| Motor frame | The fan has a square plastic casing measuring 92 × 92 × 32 mm and weighs 0.19 kg. Mounting is done via flanges with ISO 4762 M4 screws, degreased and without washers. The maximum tightening torque is 80 Ncm in all corners. The mounting position for the shaft is optional. |
| Casing | plastic, square |
| Impeller | The impeller is made of plastic and rotates clockwise when viewed from the rotor side. The airflow direction is out over the struts. At nominal operating conditions (3050 rpm), the fan delivers a maximum free air flow of 91 m³/h and a maximum static pressure of 64 Pa. |
| Bearing type | ball bearing |
| Motor protection | automatic restart at locked rotor |
| Rotation direction | clockwise |
| Motor type | The motor is a DC motor with electronics without extra functions. It has reverse polarity protection via a rectifier diode. In case of a locked rotor, automatic restart is activated with a blocking current of approximately 700 mA at nominal voltage. The voltage range is 6–15 V with a nominal voltage of 12 V. |
