Hi There !

I want to buy a humongous fan.  Need regular
household electrical specifications (i.e., 115 volts--not 230 volts).  

The biggest I've found is a 19,460 CFM.  Please see link below.

A 5-star answer would be one or two other models with higher CFM.
Price is not a factor.

All comments greatly appreciated.

Thanks!
ron

I hope one of these is suitable!

Terrific answer, Jack.  I was especially impressed that the Emerson
(34,000+ CFM) must be mounted 10 feet above the floor.  Either they're
afraid of an inadvertent haircut, or the fan moves so much air they
want to avoid vortices.

Great finds.  Thanks again!!

Here's a 29000 CFM ceiling fan. Nice price, too:

Looking Forward, denco-ga

Pinkfreud---I agree!  The price seems to be a bargain.
Thank you, as always. 
ron

denco---this is great.  I had not considered a roof exhauster. 
Reminds me of the "whole house fan" we had in the attic when I was a
kid.  Thanks!   ron

Of course, I was drifting off to sleep before it struck me!
