This cabinet is not represented with a dust collector as standard equipment. We offer it in this manner because it is common industrial customers with large dust collection systems in their facility will plumb their existing vacuum systems into a cabinet like this. Whether you use an existing dust collection system or buy one offered from Redline, you'll definitely need to do something or you won't be able to see inside the cabinet. As far as we are aware, there are no laws governing vacuum systems and media blast cabinets, at least, not in FL where we are located. Thanks for shopping with us Roland.
