Me? Yeah, it's all enclosed, but I have a shop-vac hooked up to suck out the dust, and the media does break down into dust after awhile. I'm sure that there are harder media's that don't break down, but I've had mine for 5 years and I'll bet I haven't gone through more than 4 or 5 bags of sand, and it's full right now. It holds 2 bags, maybe a little more, even. For some reason, I can't find any pictures of it on my computer. Maybe I'll take some and put them on the home-made tools thread.
