Heaps of air flow as I said above, way above what any hobbyist would find practical. I was asked to supply a CV Max to a start up chair manufacturer and we look at some sort of sanding station and DD table for finishing and after a bit of thought it was obvious we could get a better and cleaner result by venting a small room with the Max and the dust never got into the factory work area. It also could be used for spraying finish which was a bonus.
