WANG R&ace cooperates with Shangai Jiao Tong University on technology, External Rotor Fan Blade adopts advanced aerodynamic design, which is beautiful appearance, high efficiency.
Fan rotor is directly with rotor and blade, that adopt dual-sided dynamic balance, dynamic balance achieved G6.3.
The fan blade, rotor and grid is all sprayed, the surface is bright appearance that is not easy oxidation and discoloration, and has good corrosion-resistant effect, Motor Cover also by the special treatment.Fan normal ambient temperature: -25°C~+60°C, if the temperature range exceed the above, our factory can be customized according to customer requirements.The insulation grade of currently supplied fan is B-class, F-class and H-class, the protecti- on class is IP54. At present, we can also supply the fan of working environment temperature: -40°C~+60°C and -25°C~+80°C. All fans can install thermal protection in them. Our factory will put out the IP56 external rotor motor with new structure soon and this structure has got natio- nal patent. It can apply to the high humidity and bad environment.Fans have single-phase capacitor running and three-phase asynchronous running. Sing- le-phase motor has 220V/50HZ and 220V/60HZ. Three-phase motor has 380V/50HZ and 380V/60HZ. At the same time, we can provide our customers with motors of the special requi- rements: special voltage, dual voltage and so on.The line fan motor can be directly leaded out and can provide various forms of water-proof junction box for the user’s selection. Fan flow curves acquisition developed by the Shanghai Jiao Tong University Air-cooled Technology. The testing data collected from the wind room is accurate and reliable.
