Do compressor water/oil separators go bad over time?
I've been trying my hand at spraying lacquer and I seem to wind up with what looks like little bubbles in my finish. After trying a number of things to resolve what looked like solvent pop, I now think it isn't bubbles, but rather some contaminant which is coming from my ancient compressor. I got the water/oil separator when I got the compressor some 35 years ago (the compressor was probably 10 years old at the time !).
So, back to my original question - do the seperators quit doing their job after just a few decades? I'm not sure how good the separator was to begin with.
If I should get a new one, can someone offer some brand recommendations?
