I think a guy could make a reclaimer... and make it cheaply. All it is, or does, is to change air direction which causes the larger chunks to "drop out" of the air stream. In fact -- just dropping velocity for just a bit would probably do the trick... In the sense of the dust and grit get picked out of the air in the blast cabinet.... then they go into the reclaimer... my guess is that there's a "wall" between the intake and the suction side with openings at the top and bottom -- and the heavy grit hits the wall and drops into the bottom. The dust continues on into the vac. Just guessing here about how it works but it certainly seems like a simple enough contraption.
It's the fine fine dust that's killing the vacuum... they just can't handle that kind of fine dust.
