A way to prevent this spitting, is to add a water filter to
the air line. Put one at the compressor out line. Use metal lines
with a slope away from the comperssor. At the low end place a
double valve with a pipe between then once in a while drain. Also
drain the tank once in a while. Another source of spitting is cheap
air tools and leaky air fittings. Sanders and other finish tools
are desigined to minimize spitting. Air wrenches do spit and need
lubrication. I have one line with a lubricator on the end. This
line and a seperate hose is used for heavy tools. For painting I
use a clean line and hose.
