Blast Cab Filter

[TopherGreen]

I am sure this has been discussed and I have found a few threads that people talk about this but no real instructions. I have a Clarke small blast cabinet and it has just a simple cone filter covering a pressure release hole. This filter is stopping up constantly like every 2 or 3 minutes. I am using black beauty sand and would like to start using glass but the dust is just to much. I thought about the 5 gal bucket and a shop-vac thing but what keeps the media from escaping the cab? I was thinking about putting a super fine screen over the hole where the filter is but I think the media would just stick to it due to the suction of the vac. So can anybody explain how to do this and it work properly. Thanks in advance.

just fill the bucket half full of water, the solids fall into the water and filters the air they use these all the time with sheet rock sanders.good luck,mike.
