My compressor blew up for the second time this past Fall. So I have been looking and checking Craigslist for a few months.
Last week I almost ordered a Quincy QT-54. Found one locally on Craigslist, nearly new, for $3-400 cheaper. It's sitting in the shop today. Need to run a new circuit and might just run all new air lines.
So here is something I am looking into. I want dry air. So I am thinking about engineering my own system. I simply don't want to spend an extra $200-1000 on a commercial air dryer.
I'm thinking about running the air from the compressor head into several vertical pipes 12 ft. high with drains in the bottom. Next I will run the air from the tank into particulate filters and then into a home made desiccant filter. I just can't see the value of buying desiccant filters at $50-100 each. Especially when I can buy 1.5 lb cans of desiccant from Walmart. Silica gel can be dried out in an oven or in a dehydrator for next to nothing.
