Man, I went down this EXACT path one month ago (except I bought the Goodyear 3/8" hose instead of Flexzilla). Milton V style fittings. Worried about CFM restriction. There's no "right" answer to your question because the answer depends on how you use air. But here's where I landed, so take from...
That motor is only 2 hp (even though it looks huge). That can't be enough for a big 2-stage compressor like that. Perhaps it has a tiny sheave on the motor so that it's not drawing too many amps, but I would bet that one of two things are happening:
1. The motor is overloaded (an ammeter would...
Ummm, it's 2.1 SCFM, not 21... :)
My local HF had one of those functioning on display (as in actually RUNNING), and I was blown away by how quiet it was! For light air needs, this thing seems perfect. Light and quiet. Hopefully they're somewhat reliable as well.
I know this is too late to help Todd out, but from the department of better-late-than-never, I wanted to offer more of a definitive answer on this so that others can benefit. High pressure air should never get to to where it's leaking from. There is an o-ring that should prevent it. However...
Again, I know it's an old thread, but it's still worth answering for others who stumble upon it.
The gaskets are different for the low vs. high pressure cylinder. On the low pressure (larger) cylinder, the copper gasket goes between the intake valve and head. Aluminum goes on exhaust valve...
I know this is an old thread, but since these Champion compressors will be around for decades more (because it's almost impossible to kill them!) I thought it would be worth adding my $0.02.
malibu101 is correct in saying that head pressure is released through that hose when the compressor...
I wanted to take some time to post the ongoing progress of my garage air compressor project. This is my first real post on this forum, but I learned a TON of information from here, so I thought I’d try to pay some of that back. Hopefully some of this is entertaining, enlightening, or in some way...
Oh, and will do, Mike! I'm actually going to give a pretty detailed write-up of a Champion air compressor project I took on (which actually turned into TWO Champion air compressor projects).
