|---|---|
| Airflow at 0 Pa | 545 m³/h |
| Speed | 5000 rpm |
| Power | 32.5 W |
| Voltage | 48 V DC VAC |
| Motor frame | The fan is mounted via a flange with screws according to ISO 4762 M4 (degreased, without washer). The maximum tightening torque when mounting over both mounting flanges is 460 Ncm in all corners. The mounting position for the shaft is optional. The total depth is 51 mm and the mass is 0.91 kg. |
| Casing | metal, round |
| Impeller | The impeller is made of plastic and has a diameter of 172 mm. It rotates counter-clockwise when viewed from the rotor side, and the airflow is directed out over the support struts. At free air flow and 5000 rpm, a maximum airflow of 545 m³/h and a maximum static pressure of 400 Pa are achieved. |
| Bearing type | stainless steel ball bearing |
| IP class | IP68 |
| Rotation direction | counter-clockwise |
| Motor type | The motor is a DC motor with electronic speed control via PWM signal (1–20 kHz, typically 2 kHz). The nominal voltage is 48 V DC with an allowed voltage range of 36–60 V. The motor has reverse polarity protection via a rectifier diode and automatic restart in case of a locked rotor. IP68 protection class makes the motor suitable for use in humid and dirty environments. |
