I'm having some moisture issues with my garage compressor that maybe someone can help with. My setup is a 60gal upright Campbell housefield, water separator, regulator, 40ft hose. My issue is that after the compressor fills 3-4 times while using a grinder or da I get a good amount of water coming out. The water separator will have little or nothing in it. This happens all seasons, high an low humidity. Winter time the garage is heated. Short of a dryer on the end of my tools any suggestions?
 
i had that problem with an outdoor gas powered air compressor we have at work. the hot pump air meets cold tank and booom!!! the only thing i found to work well was to put air brake fluid in there. we add this to the air tanks on our tractor trailers at work in the winter for the same reason. seems to help alot and can be bought at most auto parts stores it is an alcohol based product. I would be careful if you plan to paint with that compressor though BC it does contain some kind of rust stopper. And you would want to put like a gallon in the tnk and leave it till spring, you dont drain it, hope this helps
 
A heat sink of sorts will get the job done...

I used a coil of copper and then an air separator.. add a few drains. Once you get into bigger compressors you need air driers.
 
The reason the air drier isnt working is because the air is still to hot when it passes the drier... you need to cool the air as fast as possible.
 
I paint with it so oils or additives are out. I'm thinking maybe I'll get some pipe and create a manifold on the garage wall so that I can remote mount the dryer. Do you have any pics of your copper heat sync?

This. I have a 30ft. section of soft copper coiled between the outlet on the compressor and the water seperator. This gives the air a chance to cool and let the water drop out so the seperator can pick it up.
 
Shiiiiiiiiiiit just sweat the pipe to an ac condenser from a car lol.

Just make sure its up and down ish so you can drain it and the lowest point is the ball valve.
 
Don't run your cooling tube in a coil. Run it side-to-side with a constant downward slope, so any moisture will end up at the bottom. Then, at the bottom add a down pipe with a drain in it. This guy's setup isn't the prettiest, but it should give you a good idea of how to do it. You can just use one long piece of pipe with curves at the sides instead of elbows like this guy did:
