ventilating blasting cabinet: how?

I got ahold of an old vac motor, and made a cage for it out of perforated metal, and just put two shop vac filters plus the foam precleaner filter on the cage. Been going strong with no signs of problems using aluminum oxide grit in my blast cabinet. I used a 5 gal bucket with snap on lid for the vac container.

Hi,

I succeeded in building a blasting cabinet. Now I will (for the beginning of blasting jobs) use iron furnace slag. This is showing to give a great dust in the cabinet. Which is the best technique to take away this 'mist'? Sucking it away with a household vacuum cleaner may work, but is said to destroy the engine of the cleaner soon due to particles penetrating the dust-filter. A professional tool will be beyond budget..

Has any of you blasters a useful suggestion for me?

Thanks a lot! rob

If you live where the dust wouldn't be a problem, simply use a small squirrel cage blower to duct the interior of your cabinet to the outside environment. I've disposed of my blasting dust that way for years. Works great. I use a 4" dryer vent through the wall of my shop, to which I attached, with a mounting block, the blower. Blower size? Something that will move around 100 CFM should work nicely. Keep in mind that you're building a pressure in your cabinet with the air you use, so you have to move more air than you are dumping, otherwise it will still dump dust in your shop. Shop vacs? I've used them, including the one that originally came with my commercial blast cabinet. They're a PIA, what with their restrictive dust filter. Still, when one has no other options, they do solve the problem.

Shucks. I was looking for a bag with a 600cfm capability. Hmmm, maybe half a dozen of the suckahs...

I just took a look online to see what was available and found this very, very scary site:

Thanks. See if you can find a rating listed somewhere, hopefully 99.5% of 1/2 micron particles, etc.
