Air Compressor Set-up suggestions needed

i put a dryer/filter right at the compressor. i also put a shutoff valve right before the dryer (so i can cut the air to the line and drain the dryer.) when i paint i use a totally different air hose(one that is set aside just for painting) and drain the air and moisture out of the compressor. i also buy a disposable dryer to put right at the spray gun to catch the moisture that the other dryer doesnt get. dont settle for a cheap dryer, buy a good one that will get alotof the moisture out.

i can post a pic if wanted

also drain your compressor every so often, the moisture build on the inside can rust the compressor from the inside out.
