High-Efficiency Oil-Free Compression System—Energy Saving

* Using German technology, the newly designed oil-free main engine has a large capacity and low energy consumption.
* Provide real oil-free compressed air to avoid safety problems caused by unclean compressed air
* With a new design, our oil-free compressor system minimizes lubrication consumption, less wearing parts, and has low operating costs. Ideal for long periods of continuous operation.
* With a new casing design, the machine is more compact and runs more quietly.
* Compact design, the machine is easy to install and saves your installation cost
* With labyrinth and centrifugal shaft seal design, our shaft seal can not only prevent lubricating oil and other impurities from entering the compression chamber but also avoid air leakage, ensuring that our machines provide pure oil-free compressed air.

Two-Stage Compression Technology

Our machines adopt the two-stage compression technology, which not only increases the efficiency of compression but also avoids the negative influence from the high discharge air temperature and increases the reliability and running life of airend.

Our Benefit

1. Imported premium principal engine. It is the third generation product of the world-class brand an asymmetrical 5:6 toothed rotor with outstanding performance and high efficiency much higher than comparable brands.

2. Control system that is fully intelligent and has an LCD display equipped with self-diagnosis and security devices remote control, and interlocking for multiple hosts for unattended and advanced operation.

3. Three-phase asynchronous motor devoted to Y series compressors bearings from world-renowned brands imported F-class insulation, IP54 is particularly suitable for long-term use, secure and reliable.

4. Filter for imported oil, gas and oil Separation filter, 3-way separation in order to make sure that content of oil is not more than 0.001ppm The main body is constructed of metal pipethat is safe to use for a long time with no leakage or deformation. This V-shaped conveyor belt that is imported from Germany has a lifespan that exceeds 10,000 hours.

5. Automated intelligent control of the air volume, and automatic shut-down when the speed of idle is extremely long and ensuring energy savings by more than 25 percent.

9.6 A valve-less circuit for oil makes operation of the entire machine more secure and safer. The main engine uses specially-designed compressor oil imported from the United States which minimizes the external and internal leakage in the compressor, enhances the performance for the primary engine and extends the lifespan of the machine.
