| Motor frame | The fan has a square plastic housing with dimensions of 92 × 92 × 25.4 mm and a weight of 0.106 kg. Mounting is done with M4 screws (ISO 4762, degreased) without additional support or washer. The mounting position for the shaft is optional, and the maximum tightening torque during assembly is 40 Ncm in the cable corner and 60 Ncm in the other corners. |
| Casing | plastic, square |
| Impeller | The fan impeller is made of plastic and rotates counter-clockwise when viewed from the rotor side. The airflow is directed out over the struts. In free air conditions and at 3000 rpm, the fan delivers up to 91 m³/h and a maximum static pressure of 47 Pa. |
| Bearing type | ball bearing |
| Rotation direction | counter-clockwise |
| Motor type | The motor is a DC motor with ball bearings and protection class III. It features reverse polarity protection via a rectifier diode and automatic restart in case of a locked rotor. The nominal voltage is 12 V DC with a voltage range of 8–15 V. The motor lacks electronic speed control but has an alarm signal output (open collector) for rotation monitoring. |
