|---|---|
| Airflow at 0 Pa | 178 m³/h |
| Speed | 13,000 rpm |
| Power | 25W |
| Voltage | 24V DC VAC |
| Motor frame | The fan measures 80 x 80 x 38 mm and weighs 220 grams. The casing is made of plastic. Mounting is done with ISO 4762 M4 screws without a washer and without additional support. The maximum torque for the corners with cable mounting is 50 Ncm, and for the other corners, it is 110 Ncm. |
| 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 outwards over the struts. At free airflow and 100% PWM, the fan impeller reaches up to 16,500 rpm with a maximum static pressure of 845 Pa and a maximum free airflow of 178 m³/h. |
| Bearing type | ball bearing |
| Rotation direction | counter-clockwise |
| Motor type | The motor is a DC motor with electronic speed control via PWM signal. Nominal voltage is 24 V DC with an operating range of 16–32 V. The motor has reverse polarity protection via a P-channel FET and automatic restart in case of a locked rotor. The motor shaft can be mounted horizontally, and the ball bearing system provides an expected lifetime (L10) of 62,500 hours at 40 °C. |
