Um, they make driers and filters for air lines for just such an
occasion. They also make oilers that put air Into the line for
equipment such as air nailers and wrenches that LIKE oil in the line.
Also if your air compressor is the oil type and the oil iscoming out the
air line you need to fix your compressor!!
Yes it is VERY normal for water to condense in air compressor tanks.
These days there are systems that drain the water automatically. However
in my high school days I worked in a small shop that had two compressors
with 250 gallon tanks. One night we noticed the compressors cycled a lot
but ran for a very short time. When I mentioned this to the boss he told
me to 'drank the tank' and pointed at a bucket and a valve on the tank.
It being very late and I very tired I didn't think, I just stuck the
bucket under the open pipe (about an inch and a quarter or so) and
opened said valve. Now looking back it doesn't take rocket scientist to
realize that the water in there would come out with 'some force' (about
150PSI as I recall.) Said water did NOT stay in the bucket but rather
shot straight up soaking me and everything within 20 feet. Needless to
say several things were true. a) The water was ugly dirty from the rust
in the tank. b) I could NOT close that valve fast enough, c) The boss
was laughing his arse off, d) I had gotten got. Turns out there is a
hose fitting down there too and we hooked up the big 3/4 Inch hose
hanging outside the door and drained the tanks. Clearly it hadn't been
done in a while because I spent a long time watering the weeds out back.
At 150 PSI with a 3/4" hose I felt like a fireman blasting water all
over while i stood there and 'dried out'......

That's because there are compressors that require oil for self

There are also compressors that are oil free. In my experience, the former
type lasts longer due the film of oil on the internal parts.
Not that this has anything to do with computers............ :-))

My father-in-laws air compressor seems to put out a small quantity of oil
or water when you use the sprayer so I'd be careful with that technique on
computer equipment.
