|---|---|
| Airflow at 0 Pa | 520 m³/h |
| Speed | 4300 rpm |
| Power | 41 W |
| Voltage | 24V DC VAC |
| Motor frame | The fan has a metal casing with dimensions of 160 mm width, 51 mm depth, and 172 mm diameter. Mounting is done via mounting flanges with ISO 4762 - M4 screws, degreased and without washers. The mounting position for the motor shaft is arbitrary. The maximum tightening torque during mounting is 380 Ncm at all corners. |
| Casing | metal |
| Impeller | The impeller is made of plastic and designed for a mixed-flow fan. Under nominal operating conditions, a maximum free air flow of 520 m³/h and a maximum static pressure of 425 Pa are achieved. The optimal operating point is 340 m³/h at 131 Pa. The direction of rotation is counter-clockwise when viewed from the rotor side. |
| Bearing type | ball bearing |
| Motor protection | automatic restart on locked rotor, internal fuse 4 A |
| Motor code | DV6424/12 |
| Rotation direction | counterclockwise |
| Motor type | The motor is a DC motor with a nominal voltage of 24 V and a voltage range of 16–28 V. At nominal voltage and free airflow, the motor consumes 41 W with a current consumption of 1700 mA. The motor has built-in reverse polarity protection via a rectifier diode and automatic restart in case of a locked rotor. An internal 4 A fuse (Littlefuse NANO2 series) protects against overload. |
