Datasheet (PDF) - download| Product attribute | Value |
|---|---|
| Airflow at 0 Pa | 46 m³/h |
| Speed | 6850 rpm |
| Power | 2.4 W |
| Voltage | 24V DC VAC |
| Motor frame | The fan has a plastic casing measuring 60 × 60 × 25 mm and a mass of 70 g. It is mounted using ISO 4762 M3 screws, degreased and without a washer. The maximum tightening torque during assembly is 10 Ncm at the cable outlet corner and 20 Ncm at the other corners. The mounting position for the shaft is arbitrary. |
| Casing | plastic, square |
| Impeller | The impeller is made of plastic and rotates clockwise when viewed towards the rotor. The airflow direction is outwards over the struts (air outlet over struts). At free airflow and 6,850 rpm, the impeller delivers a maximum airflow of 46 m³/h and a maximum static pressure of 105 Pa. |
| Bearing type | ball bearing |
| Motor protection | automatic restart on locked rotor |
| Rotation direction | clockwise (viewed facing the rotor) |
| Motor type | The motor is a brushless DC motor designed for 24 V nominal voltage with a voltage range of 18–28 V. It has reverse polarity protection via a rectifier diode and automatic restart in case of a locked rotor. The locked rotor current is approximately 500 mA, and protection class III applies. The estimated lifetime is 70,000 hours (L10) at 40 °C ambient temperature. |
