Sullair 185 has oil in air discharge line

I changed the separator after it had an internal issue about a year or more, the compressor produces air just fine but has an unacceptable amount of oil thru pressure hose.

Good day sir. My question is about our at last copco model:GF11FF why always discharging of oil and hightemp?

Possibility that the orffice in the scavenge line is plugged . Oil gets pushed out of the unit and the temp rises. May also be the spin on separator Bad. Separator should be changed at least once per year.

I have a atlas copco compressor 185 after I change the separator it is blowing hot air and keeps turning off

The change may have stirred up the oil; and subsequently, a piece of dirt or sludge is lodged in thermostatic mixing valve or separator scavenge line. Because it is sounds like it is shutting down on high heat, I would look at the mixing valve first.

What would cause compressor oil to migrate to dischage air.

If it is a screw compressor and by you saying you replaced the seperator i would say it it you need to check the scavange line. This is a pipe that goes to the bottom of the seperator filter and sucks any excess oil back into the bottom of the element (pump ) if this is blocked oil will pass down the line insted of going back into compressor. Check pipe on seperator and flex hose going from seperator vessel to bottom of element.

I have two comp and they both are now dumping there oil throgh my air dryer.

With out a model # my suggestion would be to replace the separator on both units. Also make sure the scavenge line is not plugged. The separator removes oil from the compressed air and the scavenge line sucks the oil that is removed by the separator back to the air end. If either the scavenge line is plugged or the separator is fouled (dirty) the oil builds up and is carried over to the dryer and eventually Thur out the entire air system. If your equipment being used can not take any oil you need to take care of this problem asap.

Sullair 185 screw compressor

The sullair 185 has a low oil pressure override button that you have to hold in while starting. after the oil pressure builds up(takes about ten seconds) you can release the button and the machine should continue to run.
