I have a CNC plasma cutter very near completion and I am searching for a way to reduce the fumes and dust a plasma cutter generates. This is going to be used industrially on a warehouse mezzanine. I was looking at a unit like this....

Sentry Air said this should work great as far as removing plasma cutter fumes, but I am not convinced this will do anything about the dust. The table has a 4' x 6' cutting area and this unit would be mounted to a shroud about 3 feet above the table. Is it just a fact of life that my warehouse will be covered in black dust now or should this do the trick? Also, its not exactly cheap at $1600. Its worth it to me if it prevents dust from getting everywhere, but is there a better option out there within $1600? Thanks
