At one point in time the company for whom I work had a flying probe tester=
for PCB's which used a cushion of air to "float" the moving parts and any =
water droplets, any at all, would cause the thing to crash.=C2=A0 Therefore=

Of course a water droplet passing though your paint gun can ruin your whole=
day, but other than that I'm with you.

Howdy,
Are you painting or in a super high humidity environment or something?=C2=
=A0 My experience with compressors is that mostly I can remember to drain t=
he tank every now and then and it all "just works" without any elaborate co=
olers / separators / whatever.
YMMV.
