| Motor frame | The fan has a square metal casing measuring 119 × 119 × 38 mm and weighs 380 g. Mounting is done with ISO 4762 M4 screws without additional fasteners or washers. The mounting position for the shaft is optional, and the torque limit varies depending on the mounting corner: 420 Ncm at the cable corner and 600 Ncm at the other corners. |
| Casing | metal, square |
| Impeller | The impeller is made of plastic and designed for axial airflow with air intake over the struts. At nominal voltage and free airflow, a speed of 4,400 rpm is achieved. The maximum free airflow is 227 m³/h, and the maximum static pressure is 180 Pa. The optimal operating point is 130 m³/h at 79 Pa. |
| Bearing type | ball bearing |
| Motor protection | automatic restart on locked rotor |
| Rotation direction | clockwise |
| Motor type | The motor is a DC motor with a nominal voltage of 24 V and a voltage range of 12–28 V. Power consumption at free airflow is 11 W at nominal voltage. The motor is equipped with reverse polarity protection via a rectifier diode and automatic restart in case of a locked rotor. Locked rotor current is approximately 1,900 mA at nominal voltage. |
