Robert,
There's a mountain of information in the archives, I'd start a search with "Yong Heng" and "best-homepro." Lots of folks here ready and able to help with questions, too. That's a cheapo 10" box fan behind the compressor and the green bottles are ice-filled, just some tricks and tips others have shared for keeping the compressor cool. Hate to admit it but I get almost as much a kick out of using this fill station as I do shooting my PCPs. Pretty weird, WM
