|---|---|
| Airflow at 0 Pa | 115 m³/h |
| Speed | 6200 rpm |
| Power | 6.8 W |
| Voltage | 24V DC VAC |
| Motor frame | The housing is square with dimensions 80 × 80 × 25 mm and is made of plastic. Mounting is done with ISO 4762 M4 screws, degreased and without washer or additional support. Maximum torque during mounting is 30 Ncm at the cable corner and 50 Ncm at the other corners. The unit weighs 110 g. |
| Casing | plastic, square |
| Impeller | The fan wheel is made of plastic and rotates counter-clockwise when viewed from the rotor side. With unrestricted air supply, a maximum airflow of 115 m³/h and a maximum static pressure of 133 Pa are achieved at 6200 rpm. The optimal operating point is at 94 m³/h and 36 Pa. The airflow direction is outwards over the struts. |
| Bearing type | ball bearings |
| Rotation direction | counter-clockwise |
| Motor type | The motor is a DC motor with electronic speed control via a PWM signal (1–30 kHz, typically 5 kHz). The rated voltage is 24 V DC with an allowed voltage range of 20–26.4 V. The motor has reverse polarity protection via a rectifier diode and automatic restart in case of a locked rotor. The electronics provide a speed signal via a tachometer output (open collector, 2 pulses per revolution). |
