Steve, I don't have a blast cabinet.

So, bear with me...does the filter trap blast media along with the dust? Are you running a paper filter in the vacuum as  well?

I wish I had a cabinet so I could copy.     frustrated

If you can't fix it with a hammer, It must be electrical.

In an ideal world, only the light dust (mill scale, rust, etc.) will be floating in the air inside the cabinet. The heavier abrasive particles will fall to the bottom of the cabinet where they will be picked up by the gun and shot out again. In practice, some abrasive does end up in the bucket. I'm only running the foam wet pickup filter in the vacuum. A little bit of water ends up in the vacuum, but no dry dust.

You're off to one heck of a start on that device, and you can improve on it big time by shortening the inlet so it is about 1/4" above the water surface.  Another improvement is to get the dips out of the hoses.

You can also gain a lot by moving the cabinet suction down to just below the shelf in the cabinet, and adding an atmousphere inlet with a flap valve where the current suction port is to provide makeup air when the gun isn't adding air to the cabinet.

Thanks for the tips.
