Cas Staff asked 5 years ago

We have oil free compressor atlas copco zr 55.
After we replace oil seal ( seal ring p/n: 1202 5245 00) with non original part, we have this problem:

Element 1 Outlet Temperature reach 225 deg. Celcius.

Intercooler Pressure reach 3.9 bars.

Milky oil in oil tank.

We have checked intercooler, aftercooler, water separator, inlet valve, replace air cleaner; but all that actions didn’t solve the problems.

Please share your experiences and knowledges.
Thank you
