After you determine the air space of a cabinet/dust collector, the next thing you need to do is check on the capacity of the vacuum system you plan to use with your cabinet if you are using separate components. The capacity has to do with the motor of the vacuum system and how large the filter system is. You want to have a dust collector that can exchange the air space inside your cabinet at the minimum 10 times per minute; more is, of course, better… to a point. You don’t want a vacuum that is so strong that you can’t move your hands and that would suck out all of your abrasive while blasting.
