The 1200XL looks like it would work, but I think it's more than you need depending on the size of your hood. Have you looked into the hydroponic blowers like the Can Fan or Vortex that are available at places like
www.mdhydro.com and other hydro suppliers? I have the 8" Vortex that is 747 CFM which works very well with my hood that has a 3'x2' opening. The low profile Can Fans are supposed to be a little quieter, although I have no complaints about mine.
