Separator filter

I'm not sure from your first post if have checked the separator and the separator filter to be sure they are working properly.

For a manual, if you haven't got one, talk to the manufacturer:

It's a bit hard for anyone to offer specifics as you do not indicate the make or model of your compressor.

You should check the manual to see about the oil separator on your compressor. This strips the oil from the air stream entering the tank, and if it is not working properly, more oil than normal is getting into the the compressor tank and into the air mains.

There is also typically a filter element in there, and yours may be plugged.
