|---|---|
| Airflow at 0 Pa | 285 m³/h |
| Speed | 13,000 rpm |
| Power | 50 W |
| Voltage | 24V DC VAC |
| Motor frame | The fan has dimensions of 92 x 92 x 38 mm and weighs 290 g. Mounting is done with M4 screws (ISO 4762, degreased, without washer or support bracket). The mounting position is optional. The maximum permissible tightening torque during mounting is 30 Ncm at both the cable corners and the other corners. |
| Casing | plastic, square |
| Impeller | The fan impeller is made of plastic and mounted in a 92 x 92 x 38 mm plastic housing. The airflow direction is out over the struts. At maximum speed (13,000 rpm), the fan delivers a free airflow of 285 m³/h and a maximum static pressure of 800 Pa. |
| Bearing type | ball bearing |
| Rotation direction | clockwise |
| Motor type | The motor is a DC motor with electronic speed control via PWM signal (1–5 kHz). Nominal voltage is 24 V DC with an allowed voltage range of 12–27.6 V. The motor has reverse polarity protection via rectifier diode and automatic restart in case of locked rotor. Locked-rotor current is approximately 6,500 mA and inrush current at startup is 34,000 mA. |
