| Impeller | The fan impeller is made of plastic and is designed for radial discharge with axial intake, classifying the unit as a centrifugal blower. At a nominal speed of 2500 rpm, a maximum free air flow of 40 m³/h and a maximum static pressure of 120 Pa are achieved. The direction of rotation, when viewed from the rotor, is clockwise. |
| Bearing type | ball bearing |
| Motor protection | automatic restart on locked rotor |
| Rotation direction | clockwise |
| Motor type | The motor is a DC motor with electronic control and protection class III. It has built-in reverse polarity protection via a rectifier diode and automatic restart in case of a locked rotor. The voltage range is 12–28 V DC with a nominal voltage of 24 V DC. At nominal voltage and free airflow, the motor consumes 5.6 W and 234 mA. |
