90NM3 200bar High Pressure Oil Free Oxygen Compressor

 1. Totally oil free ,absolute no oil inside, very safety 

2. Stainless steel cylinder ,4 cylinder two line design ,all cylinder vertical cylinder ,both piston left and right side same working condition,and same worn condition ,last longer maintenance time

3. Vertical cylinder and piston working condition,There is no lateral force, only acting in the vertical direction,Energy saving ,less electrical consumption for same gas work

4. 4pccs Stainless steel water cooler, better heat dissipation effect of cylinder

5. 4 pressure stage design ,each stage has safety valve and temperature sensor ,and prsure transmitter ,each stage pressure ratio 2-4 ,get balanced pressure for fronter and later cylinder, the overall cylinder has good heat dissipation and balanced stress, and all this make the compressor working heavy duty in long time

6.Patent piston and piston ring design ,including guide ring and seal ring,Self lubricating material, no oil inside， special Material formula Decrease gas leakage and make compressor working in high pressure and high temperature condtion

7.Suction terminal Y type filter, Filter molecular sieve powder in oxygen generator 1-2-3stasge  cylinder has one stainless filter, change filter element in time and make the compressor working longer and high efficiency

8.     Install pressure regulator before suction terminal, can adjust suction pressure scope, and adjust compressor flow rate speed (normally, fixed it when left factory )
