A new air compressor
Click on his description of the video. I got the cooler, fan and power supply off Amazon very reasonably priced. Check your temp in, then out and see if it would even be worth the trouble. I'm making a stab at painting my own cars, so I wanted as dry of air as I could get. I used to have an old rattle around in the floor Craftsman 5 horse compressor. Night and day difference between it and the new one! My glass bead cabinet and spray guns are where I see a tremendous difference.
