| Motor frame | The fan has external dimensions of 119 × 119 × 38 mm and a mass of 0.425 kg. Mounting is done with ISO 4762 M4 screws (degreased, without additional support or washer). The mounting position for the shaft is optional. The maximum torque during mounting varies depending on the corner: 420 Ncm at the cable outlet corner and 600 Ncm at the other corners. |
| Casing | metal |
| Impeller | The fan impeller is made of plastic and provides a maximum free airflow of 565 m³/h at 11,000 rpm. The maximum static pressure is 1,490 Pa. The airflow is directed so that air is drawn in over the struts. The optimal operating point is 390 m³/h at 485 Pa. |
| Bearing type | ball bearing |
| Rotation direction | clockwise |
| Motor type | The motor is a DC motor with electronic speed control via PWM signal (0–100%, 1–20 kHz) or analog control signal 0–5 V. Nominal voltage is 48 V DC with an allowable voltage range of 36–60 V. The motor has built-in reverse polarity protection (N-channel FET) and automatic restart upon locked rotor. Power consumption at free airflow is 127 W at 48 V. |
