Wenling Dayang Electric Appliances Factory

1. The fan blade is designed with advanced aerodynamics, which makes the fan artistic and efficient; the fan rotor adopts double-sided dynamic balance. The dynamic balance achieves G 6.3.
2. The fan blade, rotor and grid are all powder sprayed. The surface is bright, artistic and corrosion-resistant. The cover of the motor is also specially handled, which protects it from being oxidized and discolored.
3. The normal ambient temperature for the fan is: -25℃~+60℃. If the operating temperature exceeds this range, we can customize per customer’s requirements.
4. Currently, the insulation class we supply is B and F, and the protection class is IP54. The operating temperature is: -40℃~+60℃ and -25℃~+80℃. The motor can be equipped with thermal overload protector. We have launched axial fans with IP56 recently, whose structure was authorized the national patent. The new structure makes the fan applicable to humid and poor working conditions.
5. We have two kinds of the fan motors: single phase and three phase fan motor. For single-phase fan motor, 220V/50Hz and 220V/60Hz are applicable. For three-phase fan motor, 380V/50Hz and 380V/60Hz are applicable. Moreover, we can supply motors with special requirements, such as special voltage, dual voltage, etc.
6. The wire of the fan can be directly leaded out. We can also provide various kinds of water-proof connection box for customer’s selection. 

Burn out filter drier is used on the suction pipeline of refrigeration and air-conditioning. The core inside is 48% molecule and 5% carbon. It can absorb the acid and water in the system very efficiency and also can absorb injurant that burnt by the compressor. It can guarantee the whole refrigeration and air-conditioning system not be broken. The two sides of the pressure gauge can test the pressure difference of filter drier.
