You can get a decent sized oil-less air compressor for a few hundred or
less. Then a few line filters with one line filter right at the gun, the
one Evan posted works. Or you can just use a normal line filter attached to
the gun as well. All-in you can make a pretty nice clean air setup for
under $400 if you buy middle of the road stuff new. That's about how much
I'll be into my setup.
I'm the subject of cleaning, something that is great for cleaning small
parts like plumbing fittings is a ultrasonic cleaner. You fill the bath
with water but float a glass Tupperware dish in the water. You fill the
dish with clean IPA. Have two dishes, one for clean IPA one for when the
IPA gets dirty. 10-15 minutes in the dirty dish first, then 10-15 in the
clean dish. Once the clean dish starts looking dirty it's now the new dirty
dish and the old dirty dish, dispose of the IPA and wipe it out then fill
with fresh IPA. It's now the new clean dish.
The floating dish method in water makes it a lot safer to run IPA in a
cheap ultrasonic cleaner. If it ever catches fire just sink the dish in the
water.
