* 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.
