holy molly! This puma compressor is quiet. I was expecting something similar to what I get from my 120v AC oiless compressors, but was pleasantly surprised by this little thing. I can't even think of what to compare it to, it is more quiet than even my belt driven compressor in the garage. For 2-3 CFM, I couldn't be more pleased.
Of note:
It has a factory installed 50amp mega fuse. And 10ga feed wire is really at the limit. I put together an 8' extension last night with 10ga and soldered ends. I turned it off after about 2 minutes when the wire was nearly too hot to touch. I'd recommend 8ga minimum for this.
Also, I'm using SMH 50amp connectors for my hookups. Put one on the compressor, and will install others as needed for source. 1 in the back of the bronco, 1 in the back of the sequoia, one anywhere else I may need.
