|---|---|
| Airflow at 0 Pa | 350 m³/h |
| Speed | 6800 rpm |
| Power | 32 W |
| Voltage | 12 V DC VAC |
| Motor frame | The fan is mounted with M4 screws (ISO 4762, degreased, without washer and without additional braces) across both mounting flanges. The mounting position can be selected anywhere along the motor axis. The maximum mounting torque is 420 Ncm in the cable outlet corners and 560 Ncm in the other corners. The unit weighs 0.390 kg. |
| Casing | metal |
| Impeller | The fan impeller is made of plastic and mounted in a metal housing with dimensions 119 × 119 × 38 mm. The airflow direction is via air intake over the struts. With free airflow and 6,800 rpm, a maximum airflow of 350 m³/h and a maximum static pressure of 400 Pa are achieved. The optimal operating point is at 250 m³/h and 140 Pa. |
| Bearing type | ball bearing |
| Rotation direction | clockwise |
| Motor type | The motor is a DC motor with electronic speed control and a nominal voltage of 12 V DC (voltage range 9–14 V). It has built-in reverse polarity protection via a rectifier diode and automatic restart in case of a locked rotor. An internal fuse (5 A) protects against overcurrent, and the motor has an open collector tachometer output for speed monitoring. The estimated lifespan is 62,500 hours (L10) at 40 °C ambient temperature. |
