|---|---|
| Airflow at 0 Pa | 104 m³/h |
| Speed | 3450 rpm |
| Power | 3.4 W |
| Voltage | 24V DC VAC |
| Motor frame | The fan is designed for mounting via mounting flanges on both sides using screw size ISO 4762 M4, degreased and without a washer. The mounting position is optional with regard to the axle's orientation. The maximum mounting torque is 80 Ncm at each corner. |
| Casing | plastic, square |
| Impeller | The impeller is made of plastic and mounted in an axial plastic fan housing with dimensions 92 x 92 x 32 mm. At a nominal speed of 3,450 rpm, the impeller delivers a maximum airflow of 104 m³/h in free air and a maximum static pressure of 83 Pa. The direction of rotation is clockwise when viewed from the rotor, and the air flows out over the struts. |
| Bearing type | stainless steel bearing |
| IP class | IP68 |
| Motor protection | automatic restart on locked rotor |
| Rotation direction | clockwise |
| Motor type | The motor is a DC motor with a nominal voltage of 24 V and an operating range between 12 V and 28 V. With free airflow and nominal voltage, the motor draws 140 mA and consumes 3.4 W. The motor has built-in reverse polarity protection via a rectifier diode and automatic restart in case of a locked rotor. The protection class is III and the insulation meets the requirements according to DIN EN 62368. |
