| Motor frame | The fan has a square housing with dimensions 119 x 119 x 38 mm and weighs 0.54 kg. Any mounting position is permitted. Mounting screws of type ISO 4762 M4 are used, degreased and without a washer. The maximum permissible tightening torque during assembly is 120 Ncm for the corners at the cable exit and 350 Ncm for the other corners. |
| Casing | metal |
| Impeller | The fan wheel is made of metal and has a balancing grade of 2.5. The airflow direction is outwards over the struts (air outlet over struts). At 50 Hz and free air intake, a maximum airflow of 152 m³/h and a maximum static pressure of 70 Pa are achieved. At 60 Hz, the corresponding values are 180 m³/h and 80 Pa, respectively. |
| Bearing type | ball bearing |
| IP class | IP55 |
| Motor protection | locked rotor impedance protection |
| Rotation direction | clockwise |
| Motor type | The motor is an AC motor with impedance protection for locked rotor. The rated voltage is 230 V AC and the motor is designed for operation at both 50 Hz and 60 Hz. At 50 Hz, the power consumption is 19 W, and at 60 Hz, it is 17 W. The motor complies with the requirements of DIN EN 60950 and DIN EN 60335 and is CE, UL, VDE, CSA, and CCC certified. The expected service life (L10) at 40 °C is 37,500 hours at 50 Hz. |
