materials, with a dust and other solid impurities content of no more than 10mg/m³, at a temperature of transported air not lower than
-10 °C and above +55 °C

Safety requirements

According to the shock-hazard protection type, the fans refer to Class II devices (for models 100-200), Class I (for models 250-
