The specs are a little bit vague but it looks like the performance would be similar to a fein. If I did the conversions right, it looks like you would get about 7.2" HG max, with about 100 CFM.
With my pair of Lighthouse 6765-13 motors, I get I get about 10-10.5" HG with the zone valves closed and about 8.5-9 with a sheet on the table.
The low end when cutting thru parts, is about 7-7.5" HG. When cutting a lot of small parts with a trashed spoil board I don't think I have seen my gauge drop below 6.5" Both motors cost just under $250.00
