|---|---|
| Airflow at 0 Pa | 350 m³/h |
| Speed | 6800 rpm |
| Power | 28 W |
| Voltage | 48 V DC VAC |
| Motor frame | The fan measures 119 x 119 x 38 mm and weighs 390 g. Mounting is done with ISO 4762 M4 screws, degreased and without a washer. The maximum tightening torque when mounting across both flanges is 420 Ncm at the cable outlet corner and 560 Ncm at the other corners. The mounting position of the shaft can be arbitrary. |
| Casing | metal |
| Impeller | The impeller is made of plastic and rotates clockwise when viewed from the rotor side. The airflow direction is through the air intake over the struts. At free airflow and 6,800 rpm, a maximum airflow of 350 m³/h and a maximum static pressure of 400 Pa are achieved. |
| Bearing type | ball bearing |
| Rotation direction | clockwise |
| Motor type | The motor is a DC motor with a nominal voltage of 48 V and a voltage range of 36–60 V. It is speed-controlled and equipped with reverse polarity protection via a rectifier diode. The motor has automatic restart in case of a locked rotor and a locked rotor current of approximately 1,700 mA. The service life is 62,500 hours (L10) at 40 °C ambient temperature. |
