spraypaint cabine

For painting panels and other things, I build a spraypaint cabinet.
(the door-frame is from a shower, the plastic boxes from a industrial dishwasher)
in the top box there are two layers of dust filter,
in the lower box 2 layers of paintstopper filter.
the 2 fans on top are stronger than the lower ones
to get a bit over pressure.

a question,
when you spraypaint, do you use a water-trap inline with the compressor ?
what kind of paint should I use for acrylic panels ?
