I have a little bathroom, I want to have the most powerful fan in there
that I can, without obviously overdoing it - like having a lot of wind in
there! I'd put an inline fan in the attic. I'm not sure how much would
be too much. I'd like it to double as house ventilation, to empty the hot
air out of my house overnight, that's why I want a fan more powerful than
the minimum.

If you have a powerful bathroom fan, and it's too powerful, can you tell
me its CFM and what the square footage of your bathroom is?

Or, if you have a powerful bathroom fan, and it's NOT too powerful, same
thing? So I can get a ballpark idea of how much power is too much.

I could put a variable speed control on the fan, Fantech's inline fans
take a variable speed control that goes from 0-100% - so I
could put in a bathroom fan that's too powerful for the bathroom, and
use it dialed down when it's being used just for bathroom
ventilation. I guess - I don't know if there are hitches in that idea.

Thanks.
