unless you need a special kind of media, fine silica sand is what i use. i get it at the lumber yard for around $8 for an #80 bag. wear a good respirator though, not good on the lungs . you can reuse it but it gets awful dusty
Why would the Media be sandblasting? Shouldn't they be like reporting the news and stuff?
I was using silica sand, but it must not be fine enough. It kept plugging up in the hose or gun, but it sure did a good job.
Moisture in the compressed air will cause clogging...you need to filter out moisture before the air gets to the sand.
nothing mounted on the tank will work
rp7x is right. If you use a line filter to eliminate moisture it should be 20-30 feet at least from the compressor, that gives that air some time to cool down to ambient temperature and separate the moisture from itself before going through a filter that collects the rest of the water.
