300mm 400mm 500mm Axial Fan For Cold Room
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 G6.3.
2. High strength carbon steel fan blade,The fan blade is made of thick high-hardness carbon steel, cold stamping high strength, not easy to deform, not easy to fall off, large air volume, low noise, corrosion resistance, rust, and stable operation.
3. The fan blade rotor and grid are all powder sprayed are all powder sprayed. The surface is bright artistic and corrosion-resistant. The cover of the motor is also specially treated, which protects it from being oxidized and discolored.
4. The normal ambient temperature for the fan is -25 ℃ to 60℃. If the operating temperature exceeds this range, we can customize per customer’s requirements.
5. Currently, the insulation class we supply is B and F, and the protection class is IP54. The other available operating temperature is -40 ℃ to +60℃, -25℃ to +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 high humid and poor working conditions.
6. we have two kinds of 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.
7. The wire of the fan can be directly leaded out, or we can also provide various kinds of water-proof connection box for customer’s selection.
