I am a high institution student working on a project to build a small torando simulator. I need a squirrel shut within (centerfugal) fan to power it. I would prefer it run on standard 115v US home A/C power (no DC, as I do not hold a power supply). Where could I find such a fan for little money (<$50). I am looking for a aficionado with a usable air-output (not a bypass, but a bit an actual outlet for the air) and with a cfm approximately equal to a strong vacuum cleaner. (which I guess is around 200 cfm, though I do not know.)
Answers: a furnace blower will be a short time too big for what you want to do.
most furnace blowers run 8OO-2000 cfm at .50" water column static pressure.
if you in recent times need just about 200-400 cfm you might hit up an HVAC shop for an induced draft blower that you can cob onto, or just be in motion to the hardware store and buy a electric leaf blower.

Contact a HVAC shop, sometimes they will hold on to dated blowers from furnaces, other wise dance to your local dump and look in aged furnaces.
