I have the same problem, but the splatter appears only after about half an hour of painting. I guess it's because the compressor heats up and so is the air and it condenses not only in the moisture trap but in the hose too. Maybe a warmer room temperature could fix the problem. Placing the compressor on the floor don't think it will stop the water from getting to the airbrush as the air flows fast through the hose.
