| Speed | 6,700 rpm |
| Power | 2.4 W |
| Voltage | 12 V DC VAC |
| Motor frame | The fan measures 51 × 51 × 15 mm and weighs 36 grams. Mounting is done with M4 screws (ISO 4762) without a washer or extra support, with a maximum tightening torque of 100 Ncm in all mounting corners. The motor shaft can be mounted in any position. |
| Casing | plastic |
| Impeller | The fan impeller is made of plastic and rotates counter-clockwise when viewed facing the rotor. The fan is a blower type with axial intake and centrifugal discharge. At nominal voltage and free airflow, a speed of 6,700 rpm and a maximum static pressure of 170 Pa are achieved. |
| Bearing type | ball bearing |
| Motor protection | automatic restart on locked rotor |
| Rotation direction | counter-clockwise (viewed from the rotor) |
| Motor type | The motor is a DC motor without a specified separate motor designation. It has built-in reverse polarity protection via a rectifier diode and automatic restart in case of a locked rotor. The locked-rotor current at nominal voltage is approximately 300 mA. The motor belongs to protection class III and is approved according to, among others, UL507, EN 62368, and CSA C22.2 No. 113. |
