I also don't have any issues with moisture even though I live in Florida and paint outdoors. I think the long run of hose helps cool the air down before it hits the moisture trap.
Thanks, that's something else I was going to ask about. How long is the hose you're using between the compressor and trap? Outside of this forum, it's hard to sort out all the conflicting information. Makes it hard for someone like myself who knows nothing...half the pictures I see are of filters right on the compressor, and half the info I read says 38 ft are required. I'll be near a window that's going to be cracked in the winter, and your setup obviously is successfully removing water.
