1.The air end adopts water lubrication to completely replace the oil lubrication in the past, so as to ensure that the air used by customers is absolutely oil-free and pollution-free.
2.The exhaust temperature is generally not exceed 50 ℃ to ensure that the air in the compression process is close to the isothermal compression process (isothermal compression process is the most energy-saving and power-saving compression process).
3.The maintenance cost is one tenth of the maintenance cost of the general compressor. There are few maintenance parts and only need to replace the air filter element and water filter element.
4.The air end structure design is reasonable, the axial force and radial force balance each other, the spindle vibration is less, the noise is low.
5.Full intelligent control, dynamic display of system working condition, real-time monitoring of important parameters, intelligent automatic switch on and off can completely realize continuous operation under the unattended condition.

1.The double-stage compressing screw air end reduces the compression ratio of each stage and the internal leakage and improves the volumetric efficiency, it adopt large diameter rotor which is greatly improved the working efficiency compared with the single-stage air end, and the highest exhaust gas volume is achieved.

2.The equipment adopts IE4 permanent magnet synchronous motor, which makes the energy saving efficiency higher than ordinary induction motor and high efficiency induction motor, the soft starting of frequency conversion can reduce the peak current of start-up, realize the smooth start-up, and make it possible to reduce the cost of power equipment.

3.Through the optimal flow control and constant pressure control to reduce the energy consumption, make sure the pressure fluctuation amplitude is controlled within ± 0.01Mpa and the necessary exhaust volume is accurately provided by the best power.

4.The whole machine adopts direct drive, high reliability, low noise and easy maintenance.

5.Full intelligent control, dynamic display of system working condition, real-time monitoring of important parameters.

6.At the same power, the gas production of two-stage compression is increased by 15% compared with single-stage compression, which can achieve energy-saving effect of up to 15%, and save electricity by 45% - 50% compared with ordinary screw air compressor.

1.Using the valve plate of "straight side multi barrel concentric DC valve" has no fracture for life, more convenient maintenance and lower noise.

2.The connecting rod adopts needle roller bearing design, which is more wear-resistant, and the crankshaft has no wear for life.

3.Cast iron piston precision processing, more wear-resistant, not easy to deformation.

4.The imported piston ring is adopted, which has less oil consumption and wear resistance.
