oily smell in tank drain water
When I drain the air tank, red milky water comes out. Smells like oil or coolant is
mixing with the air. What else can be done or checked?
Darnell, make of compressor? Model number? Age? Hard or light use? What color is the oil in the sump?
I can't specifically help you without specific information on the compressor as not all are the same.
Please provide more information as a comment to this post.
Water accumulates in the sump oil of Ingersoll Rand
by Dave Giles
(Auckland. New Zealand)
I have bought (12 months ago) a new 2 stage Ingersol Rand compressor.
The problem is that water accumulates in the sump oil until the compressor starts to squeal. This is how it first came to our attention.
Three times we have undone the filler to find it over flowing. We have drained it, found water mixed with the oil, refilled with clean oil.
when restarted it sounds great an obvious change in pitch.
My colleagues suggest that running for approx 2 minutes at intervals of 15-20 minutes minimum to approx 30 minutes or so is about a good run time for a large industrial piston compressor
Ingersoll-Rand blowing oil
Hi there we have a problem of milky oil flowing out with the air we have changed the oil/air separator and still the same
Oil in the air in an Ingersoll Rand EP50SE rotary compressor

Ingersoll Rand EP50SE rotary screw compressor
We have a Ingersoll Rand EP50SE (rotary screw)that runs our pneumatic equipment. Recently, if I use it there is a strong smell of oil in the plant. I have had some experience with these and the 100 H.P. model. I have seen collapsed separators cause this before.
But I removed the separator and it looked fine (I replaced it anyway, it was time), it has a new air filter, I removed and cleaned the scavenger tube and have generally inspected the machine without finding out whats causing the oil in the air.
This compressor is about nineteen years old and as far as I know it is the original air end. Could wear in the air end cause this? What else could cause it? I have it shut down and I'm using our smaller back up compressor for now.
