| Motor frame | The fan has a square plastic housing measuring 92 × 92 × 38 mm and weighs 0.240 kg. It is mounted with M4 screws (ISO 4762) without washers or additional support. The mounting position of the shaft is optional, and the maximum tightening torque for mounting is 30 Ncm in all corners. |
| Casing | plastic, square |
| Impeller | The fan impeller is made of plastic and rotates clockwise when viewed from the rotor side. The airflow is directed outwards over the struts (air outlet over struts). At 6000 rpm and free airflow, the fan delivers 130 m³/h with a maximum static pressure of 205 Pa. |
| Bearing type | ball bearing |
| Rotation direction | clockwise |
| Motor type | The motor is a DC motor with a nominal voltage of 24 V and a voltage range of 11–28 V. At nominal voltage and free airflow, the motor consumes 6.5 W and 270 mA. The motor has automatic restart on locked rotor and is protected against incorrect polarity via a directional diode. Protection class III applies to electrical safety. |
