* xydf series centrifugal fan for the external rotor motor, external rotor motors of the series with a compact, easy to install, reliable operation, low noise, energy efficient features.
* xydf series centrifugal fan into operation two single-phase and three-phase asynchronous induction capacitor run. a wide variety of ground control facilities for electronic equipment forced ventilation, dust can also be used for pipe, the exhaust heat, inflatable advertising model, environmental protection and pollution control, etc..
* xydf series centrifugal fan insulation class b, class f.
* voltage: single-phase capacitor run fan to 220v/50hz, three phase wind is 380v/50hz. we can follow customer demand for the production of different voltages, fan frequency.
* fan for ambient temperatures between -30℃-60℃，relative humidity less than 90%, altitude less than 1000m.
* the average fan is applicable to life more than 30,000 hours.
* must be a ground wire motor with external grounding device before connecting the fan to use effectively.
* fan characteristic curves are circles under wind conditions and does not cover screening tests.
