| Impeller | The fan impeller is made of plastic and rotates clockwise when viewed from the rotor side. The airflow is directed outwards over the struts. At a nominal speed of 6,000 rpm, the fan provides a maximum free airflow of 130 m³/h and a maximum static pressure of 205 Pa. The optimal operating point is 88 m³/h at 65 Pa. |
| Bearing type | ball bearing |
| Rotation direction | clockwise |
| Motor type | The motor is a DC motor with a nominal voltage of 24 V and a voltage range of 11–28 V. The power consumption is 6.5 W at free air flow and nominal voltage. The motor has automatic restart on locked rotor and is protected against reverse polarity via a rectifier diode. The rated current is 270 mA at nominal voltage and free air flow. |
