1) Shenlong oil-less screw compressor uses the water lubrication screw main machine produced by European technology, cast by copper alloy with once moulding, anti-corrosion, free of deformation under high or low temperature. The inner adopts separate lubrication channel, which maximum reduced the wear of main machine and air pollution, and increase the air flow speed. It adopts the water separation and water softening system originally imported from German DOS.DS. The separation speed of water in the water-gas buckle increases to get the optimal water separation effect and to ensure the water content under air discharge less than 2mg/m3.

2) It adopts the copper, screw and sealing materials imported from DOS.DS so that the screw’s sealing and engagement are tighter and the sealing materials are more stand wear and tear.

3) It adopts imported SKF bearings plus the separate internal hermetic seal technology to guarantee absolutely zero contact between lubricating water and bearings, reduce rustiness of bearings caused by lubricating water and make sure of the service life of bearings exceeding 50,000 hours.

4) It’s water systems adopts the unique water filtration and lubrication system of German DOS.DS to make the best use of lubrication, sealing, noise reduction and cooling functions. The full automatic water control system ensures reasonable water flow and reduces the compressor’s power loss.

5) It adopts a design of double systems: air and water cooling, to ensure easy use and installation for customers.

6) It all adopts direct connection transmission with the lowest power consumption.
