Been thinking about purchasing a GX CS4 I. I see some folks are using some inline filters and perhaps water separators on their unit. I see from comments that it can take an extra 5 minutes just to bring the inline filters to pressure to begin the fill. I am wondering if your using the CS4 I just to fill straight to the gun, - it is usually a quick fill for even a 480cc bottle on an fx Crown. In a short 480cc bottle fill do you still get some moisture ? If so, then perhaps it is worth working the compressor harder with more run time and spending the extra dollars for the inline filters? I assume the longer the compressor run the more moisture buildup you get? Would appreciate any of your comments and advice. Thanks , KB
