| Motor frame | The housing is square and made of metal with dimensions of 119 × 119 × 38 mm and weighs 535 g. Mounting is done with ISO 4762 M4 screws, degreased and without a washer. The maximum tightening torque varies depending on the mounting corner: 190 Ncm for the cable outlet corner and 310 Ncm for the other corners. |
| Casing | metal, square |
| Impeller | The fan impeller is made of metal and is balanced to balancing class 2.5. The airflow direction is out over the struts (air outlet over struts). At 50 Hz and free airflow, the fan delivers 73 m³/h with a maximum static pressure of 19 Pa. The fan impeller rotates clockwise when viewed from the rotor side. |
| Bearing type | plain bearing |
| Motor protection | locked rotor impedance protection |
| Rotation direction | clockwise |
| Motor type | The motor is an AC motor designed for 230 V and 50/60 Hz operation. At 50 Hz, the power consumption is 11 W and at 60 Hz, it is 10 W. The motor is protected against locked rotor via impedance. Protection class I applies to electrical safety. The operating temperature range is -10 °C to 70 °C (50 Hz) and -10 °C to 75 °C (60 Hz) respectively. |
