I'll see what I can find... I'm from Northern California where it rains 7-8 months out of the year, and I know several people with WHF's and I've never heard of any of them being sources for leaks. Basically, they are the reverse of swamp coolers--they suck in fresh air through opened windows and vent out through existing attic exhausts (there are no new roof exhaust ports to be installed)... Although, being in Florida, is humidity often pretty high anyway?
For now, this site seems to have some decent info/pics/diagrams:

If you want more info, a lot seemed to come up when I googled "Whole House Fan"
I don't know about this particular company, but they can be pretty powerful. I work at a LFS, and my boss' 120 gallon tank crashed when he went to Thailand this year, and by the time we caught it the tank was fouled (so cloudy that even with 800 W of MH lights on a 120 we couldn't see in more then 6 inches)--very stinky. The WHF evacuated the stagnant, rancid air in just a few minutes. They work very well at flushing inside air to outside.
