Is compressor supposed to fart?

[MrBasse]

The noise you hear is just the compressor working, think of a car with no exhaust versus one with exhaust. When you plumb your system a lot ofthe noise will be contained.

It will vibrate around like crazy without being bolted down, try holding it in place and it will quiet down a bit, just don't touch the air output or hold the case for too long as it will get very hot.
