[Gasification] blower suggestions?

[John T. Frimenko]

Jim,
If you have a local Harbor Freight store, look at their dust collectors:
http://www.harborfreight.com/cpi/ctaf/displayitem.taf?Itemnumber=94029

Drive motor has two brushes; speed should be controllable, but is a 
potential ignition source. Don't know blower wheel material, assuming 
sheet metal(?). The product manual is available, from the web site.

Might be worth  consideration.

John in Pa.
