They make vacuum systems for balsting cabinets. These systems don't pull as hard as a shop-vac. My Skat Blast has a media collection box between the cabinet and the vacuum. The box allows the heavy media to drop out for recovery and not get sucked into the vacuum.
Make sure you have a good filter on your shop vac or the fine dust will tear the bearings up in the vacuum motor.
I use medium grit "sand blasting sand" when I use my pressurized blaster outside, but that sand makes to much dust in my cabinet.
Slag works great on heavy iron, but is way to agressive for light sheet metal or small aluminum parts.
TIP sells all of the different medias...call them for there recomendation on a low dust media.
