Datasheet (PDF) - download| Product attribute | Value |
|---|---|
| Airflow at 0 Pa | 680 m³/h |
| Speed | 7000 rpm |
| Power | 67 W |
| Voltage | 48 V DC VAC |
| Motor frame | The fan has a metal casing with a diameter of 172 mm and a depth of 51 mm. Mounting is done with ISO 4762 M4 screws, degreased and without washer or extra support, with a maximum tightening torque of 600 Ncm in all corners. The mounting position for the shaft is optional. |
| Casing | metal |
| Impeller | The impeller is made of plastic and rotates counter-clockwise when viewed from the rotor side. The airflow is directed outwards over the struts (air outlet over struts). At maximum speed of 7000 rpm, the impeller delivers a free airflow of 680 m³/h and a maximum static pressure of 860 Pa. |
| Bearing type | ball bearing |
| Rotation direction | counterclockwise |
| Motor type | The motor is an electronically controlled DC motor with PWM speed control and a nominal voltage of 48 V DC (range 36–72 V). It has built-in reverse polarity protection via P-channel FET and automatic restart upon locked rotor. The motor is equipped with undervoltage and overvoltage protection that shuts down the fan if the voltage is outside the permitted range. The lifespan is estimated at 62,500 hours (L10) at 40 °C ambient temperature. |
