Ray,
Mike Rambour is right: " A blast cabinet I don't think can work strictly on
incoming air pressure to exhaust the dust" - you do need an external suction
system.
Also I don't know of anyone that has a filter for the outgoing air in the
cabinet. I have used a shop vac for my exhaust system for years. The only
thing you have to watch, is that the dust will get to the motor bearings and
cause premature failure of the shop vac. To help prevent this, I suggest
that you ensure that the deflector in the shop vac. is pointing down to
help keep the dust away from the filter in the vac. Also put a couple of
inches of water in the bottom of the vac. This will help trap the dust
so it doesn't get to the filters as quick and easily. Finally, I'd suggest
that you clean the filters in the vac. after each use.
