Don, the second cabinet is the dust collector, it pull the 'fumes' from the
blast area and filters the air through the bags like a vacuum cleaner. The
trapped residue falls to the bottom. If the blast cabinet has not been used
recently, humidity or other source of moisture may have clumped up the media
so it will not flow, try replacing it. Incoming air needs to be dry. Or it
could be clogged with small pieces of rusty british cars.
