Morning all in cybeerland, we just received our new keg washer from Premier Stainless (KGW-M-02 for those interested in which one) and am in the midst of getting the system up and running. Looking over the service requirements there is one for an air compressor that can deliver 30-40 psi @ 7-15 SCFM and is oil free. I poked around on the probrewer.com forums and I see that some are skipping the compressed air and are using their existing CO2 source to purge the kegs and are using Acid #6 or similar product for cleaning in a CO2 environment. So what are my fellow brewers here using for their keg washing set ups, air compressors or straight CO2? Thanks for the help with this.
