| Motor frame | The fan measures 119 × 119 × 38 mm and weighs 0.375 kg. Mounting is done with ISO 4762 M4 screws, degreased and without washers. The maximum torque for mounting is 120 Ncm at the cable outlet corner and 150 Ncm at the other corners. The motor shaft can be mounted in any position. |
| Casing | mixed media, square |
| Impeller | The impeller is made of plastic and is designed for a mixed-flow fan. The airflow direction is outward over the struts. At free air flow and 6,000 rpm, the impeller delivers up to 280 m³/h and a maximum static pressure of 380 Pa. The optimal operating point is 185 m³/h at 137 Pa. |
| Bearing type | ball bearing |
| Motor code | DV4118N |
| Rotation direction | anticlockwise |
| Motor type | The motor is an EC motor (electronically commutated) with speed control and a nominal voltage of 48 V DC with a voltage range of 36–60 V. It has built-in reverse polarity protection via a rectifier diode and automatic restart in case of locked rotor. The motor is equipped with an internal fuse (2 A, Littelfuse NANO2 series) and has class III protection rating. The service life is estimated at 70,000 hours (L10) at 40 °C ambient temperature. |
