|---|---|
| Airflow at 0 Pa | 82 m³/h |
| Speed | 4400 rpm |
| Power | 3.6 W |
| Voltage | 12 V DC VAC |
| Motor frame | The fan is mounted with ISO 4762 M4 screws, degreased and without washers. The maximum tightening torque at the mounting flanges is 30 Ncm at the cable outlet corner and 50 Ncm at the other corners. The mounting position is optional with regard to the shaft orientation. |
| Casing | plastic, square |
| Impeller | The fan impeller is made of plastic and mounted in a plastic casing measuring 80×80×25 mm. At full PWM (100%), the fan reaches a speed of 4,400 rpm and a maximum free air flow of 82 m³/h. The maximum static pressure is 70 Pa. The airflow is directed outwards over the struts. |
| Bearing type | ball bearing |
| Rotation direction | counterclockwise |
| Motor type | The motor is a DC motor with PWM control and a nominal voltage of 12 V. The voltage range is 10.8–13.2 V and the nominal power is 3.6 W at free airflow. The motor has built-in locked-rotor protection with automatic restart and reverse polarity protection via a rectifier diode. The direction of rotation is counter-clockwise when viewed from the rotor. |
