|---|---|
| Airflow at 0 Pa | 187 m³/h |
| Speed | 2700 rpm |
| Power | 4.3 W |
| Voltage | 48 V DC VAC |
| Motor frame | The fan has a square plastic housing with dimensions 119 × 119 × 32 mm and weighs 0.23 kg. Mounting is done with ISO 4762 M4 screws without washers or additional support. The maximum torque for mounting across both mounting flanges is 80 Ncm in all corners. |
| Casing | plastic, square |
| Impeller | The impeller is made of plastic and mounted on a ball-bearing supported shaft for a long service life. At a nominal speed of 2700 rpm, a maximum free airflow of 187 m³/h and a maximum static pressure of 66 Pa are achieved. The direction of rotation is clockwise when looking at the rotor, and the airflow is directed outward over the struts. |
| Bearing type | ball bearing |
| Motor protection | automatic restart at locked rotor |
| 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. At nominal voltage and free airflow, the motor consumes 4.3 W with a current consumption of 90 mA. The motor has built-in reverse polarity protection via a rectifier diode and automatic restart in case of a locked rotor. There are no electronic functions. |
