The state clearly classifies energy efficiency levels limit value. The 2 class energy efficiency products can save 10%~15% of the power than 3 class energy efficiency products.and the 1 class energy efficiency products can save 10%~15% of the power than 2 class energy efficiency products. energy-saving effect is remarkable .
Energy -saving principle :
- Curve 12 '3' is an isothermal compression process, it form the area of 613 '4 with Y-axis which is the indicated work of isothermal compression
- Curve 123'' is the 1 stage compression process, it form the area 613 ''4 with Y-axis which is the indicator work of the 1 stage compression.
- Curve 12, 22 'and 2' 3 are the 2 stage compression process, and the sum of the area 6125 and the area 52 '34 (6122' 34) with Y-axis which is the indicator work of the 2 stage compression.
- It can be seen from the diagram that the isothermal compression process 613 '4 area (indicating work) is the smallest, but it is impossible to achieve isothermal compression in the air compressors' actual compression.
The 1 stage compression has the bigger area of power 13 '3 than isothermal compression, while the 2 stage compression saves 22" 33 "area of power.

Features description:
- Two stage compression unique air end :The two-stage compression oil-less screw machine has a unique design for air end. It combines the first-stage compression rotor and the second-stage compression rotor in a case, and rotates them directly through gears respectively, so that each stage of the rotor can obtain the best linear speed, so that the compression efficiency is higher.
- internal spray curtain cooling method: Two-stage compressed air compressor, using high energy saving internal spray curtain cooling method, good cooling effect, greatly reduce the temperature of compressed air, achieve close to isothermal compression, but also can reduce the pressure loss between the first and second, reduce the compression ratio, improve the compression efficiency
- Reduce internal leakage: Two-stage compression is adopted, which reduces the compression ratio of each compression, reduces the internal leakage from the high pressure end to the low pressure end of each compression, and improves the volume efficiency.
- Noise reduction: Two-stage compression is adopted, which reduces the compression ratio of each compression and greatly reduces the noise, especially the unloading noise
- Easy to do maintenance and service: Two-stage compressor unit, except the screw air end , other systems and structures of the unit are basically the same as single-stage compression, which brings convenience to the maintenance and use of users
- Reduce energy consumption: Energy-saving two-stage compression screw air compressor can effectively reduce energy consumption. Under the same power, the energy saving should be at least 15%-25% depending on different working conditions.
- For users with large amount of gas and continuous gas required, two-stage compressed air compressor should be given priority
- After 1 stage compression, coolant through multiple jet hole on the body, form the mist jet shade, to cool the hot 1 stage compressed air, greatly reduces the compressed air temperature before entering the 2 stage compression, which is near to isothermal compression process, save the energy compression effect.
- Even without inter-stage cooling, two stage compression is more efficient than single stage compression. This is because the volume of air becomes smaller after the 1 stage compression, so the 2nd stage compression can use a smaller diameter of the rotor, and the leakage rate of the unit volume is small.
- Reduce internal leakage: use 2 stage compression, reduce the compression ratio of each compression, reduce the leakage from the high pressure side to the low pressure side per class, and improve the volume efficiency.
- Noise reduction: the compression ratio of each compression is reduced by taking 2 stage compression, which greatly reduces the noise, especially the unloading noise
- 2 stage compression unit, except for screw air end, the other system and structure arrangement of the unit is basically the same as the single stage compression, which is convenient for the maintenance and usage to the user.
- For users who need large air consumption and continuously use, should take priority to use of a 2 stage compressed 1 class energy efficiency air compressor
