I have been fighting moisture in my air supply ever since I got my big compressor. So this thread really caught my eye. I did some YouTube searching and found a very ingenious way of obtaining dry air on the cheap. The video shows how a guy plumbed an automotive A/C condenser into his air path straight out of the compressor head and then back to the compressor tank via an auxiliary air tank which he uses as the water trap reservoir. I think you can pickup a used condenser at the junk yard pretty cheap and then all you have to by is some tubing and fittings. The aux. tank you could also source used off of Craigslist I suppose. I would need a small compressor tank rated to at least 175 psi. as that is the max for my machine. I am definitely going to do this as my blast cabinet will work so much better once I rid it of the excessive moisture in the air lines.
