Finished up my Air cooler/dryer system. I used a Derale Transmission cooler and added a 24vdc fan that kicks on when the compressor motor kicks on. 1st stage after the tranny-cooler is the water-trap, then on the output side, it goes through the usual regulator/filter/trap, 2cd micro-filter, then a desiccant-dryer. Very cool and dry air on the output side. (btw, none of the tubes are actually touching anything, it is hard to tell from the front shot). The compressor is a McGraw 29 gallon (oiled compressor), 175psi max. I really like the Oil-compressor they run sssssooooo much quieter than the oil-free compressors.
Is this all plumbed after the compressor and tank? You’ll want an auto tank drain in there too.
Bear in mind that this will only be able to drop your air down to ~ ambient temp dew point, and you’ll still need a fine particulate filter after your desiccant (for dust from the beads) before your plasma.
Hi Andy, thanks for your reply and instructional comments. So, it has dryer/collector (with auto drain) after the radiator and before the tank. Then after the tank it has a pressure regulator (with dryer/auto-drain), then discant beads, then a micron filter, followed by another smaller micron filter then out to the shop. Understood on the max/best air temp being room air temp, and that is fine with me. I was trying to cool the hot compressed air and capture the bulk of that condensation in that first primary dryer between radiator & tank.
The crazy(ist) part, was that the OE tubing that was on the compressor (china made), is it’s own size, close to 1/2” but small enough that USA made 1/2” compression fittings where to large to just flair/adapt their tubing. So had to replumb it all. Luckily the fitting threads that was on the compressor output and tank input where -8AN and faired/compression type. My concern there of course what NOT being able to get a seal. I had to “Hand Bend” (carefully) the copper tubing, I had bought one of those official benders…. but, due to the construction of the bender, co-planer bends had to be almost 10 inches away to the next bend. I needed closer together bends than that. I will probably paint the component wood mount surface as well, to cut down on some of the “Hillbilly” engineering look. I know it looks horrible as is, but I was wanting function and it is just me in my shop.
