I have hooked RovAir compressor with original filter to Hill dry pac pro filter. There is no need to use a flow restrictor screw as the two filters slow down the fill time. There is no perfect solution and this is temporary until my Hill EVO-310 compressor arrives. Then I will eliminate the RovAir compressor and filter. I don't think I have a moisture problem but who really knows. I have dry fired with muzzle a foot away from sheet of cardboard with no moisture showing. Don't know if this means anything or if there is a test.
