| Motor frame | The fan has a metal housing measuring 119 x 119 x 38 mm and weighing 0.54 kg. Mounting is done with ISO 4762 M4 screws, degreased and without a washer. The maximum tightening torque during mounting across both mounting flanges is 120 Ncm at the cable outlet corner and 350 Ncm at the other corners. The mounting position for the shaft is optional. |
| Casing | metal, square |
| Impeller | The impeller is made of metal and balanced to grade 2.5. The airflow is discharged over the struts. At 50 Hz, the fan delivers a maximum free air flow of 98 m³/h and a maximum static pressure of 27 Pa. At 60 Hz, the corresponding values are 104 m³/h and 24 Pa, respectively. |
| Bearing type | plain bearing |
| Rotation direction | clockwise |
| Motor type | The motor is an AC motor with impedance protection against locked rotor. It is designed for 230 V voltage at both 50 and 60 Hz. At 50 Hz, the power consumption is 13 W, and at 60 Hz, it is 12 W. The motor achieves a speed of 1700 rpm at 50 Hz and 1800 rpm at 60 Hz under free airflow. The L10 lifetime at 40 °C is 50,000 hours at 50 Hz and 52,500 hours at 60 Hz. |
