Is the blower just a centrifugal blower, like a dust collector or vacuum cleaner, or is it a very highspeed multistage blower?
You will not get adequate vacuum from a single stage centrifugal blower; these things are often rated up to 100 inches of water lift which might sound like a lot but full vacuum is something like 380 inches (32 feet) of water. Vacuum is normally measured as inches of mercury (Hg) and full vacuum is about 30"Hg; to get adequate holding you need to get at least two thirds of full vacuum which is about 20"Hg. The only practical way to do this is with a positive displacement pump.
An open mind is a virtue...so long as all the common sense has not leaked out.
