heh, he said cheap... your sharp probably cost me more than my whole setup incluing all the fittings to get it to connect together, assorted valves so I can turn off any part, quick connects...
- no inspection window
- the only hard part about swapping desiccant is the way I mounted it (literally, untread cap and dump it out, in theory with it mounted to the wall you can unthread the bottom cap, dump it, unthread top cap to refill, no disconnecting air lines or anything)
- No leaks- that was the big hassle with home built, I spent a lot of time chasing leaks with my older setups
- No rust that I've seen, though I don't see why it couldn't. that is the reason that I have the motorguard after it, nothing steel comes in contact with the air on the other side of the motorguard.
