Hey guys,

I just bought a new blasting cabinet. It's the one I have listed below. It works great but not for long because it fills up to the point that I can't see what I'm blasting.

Does anyone have any creative ways that I can vent this thing so I can see? I was thinking a shop vac or something like that. Any ideas that you can give me would be a great help. Thanks

Dave.

I can't believe they sell those without vacuums included. Makes it cheap but useless, eh! Maybe talk to HF and see what they have and how much they'll nick you for it. One, or both, of the plugs should get hot when you turn on the blaster, that is where you plug in the vacuum. If you just use a shop vac without super filtration it will fill your space with fine silica dust, very bad for your lungs. By the way, when you do get it working like you want remember to leave the vac running for a few minutes before you open the door! That silica dust is REALLY bad for your lungs!

Did I mention how bad that dust is for your lungs?

a shop will work.....to a point.......but you really need one of the industrial vacs/ filter that will keep the dust down

When I built my cabinet I tried a couple of my smaller shopvacs with no success but I just happened to have a larger industrial one I ended up using. I still had to add on several layers of filtration to it because of the fine dust produced. IIRC I used the filters it had plus I wrapped those up with a couple of thicknesses of something I had that was similar to a moving blanket and I had to take it out and clean it very often. Of course, I was using it for long periods (at least 4-6 hrs per nite on average) and I also placed it placed below the exhaust fans in the wall of my garage so theyd remove any dust that managed to escape the cabinet. And as evolvo said, its extremely dangerous to your lungs so its very important to also use a good respirator too

My big cabinet is about 6 ft long and I have a length of pvc in the top back with 1/2 holes about 6 " apart that extends out the end. I use another 10 ft length of pvc then the shop vac. everything is outside under a shade cover. this keeps the mess out of the shop. I have been thinking of trying a dust turbine like I have on my backhoe air intake to get out more of the dirt before the shop vac.
