Product review (2 stars): Broan Fan
You try to use the amp rating to derive fan power.
The ad shows 1.1 amp, but when it arrived it was .7 amp on the label, and the fan blade was a little crooked.

I didn't use it - I needed a fan right away so I went to the local hardware store and purchased a more powerful motor,
I'm disappointed but it was worth a try. If you're buying a fan motor, make sure it is powerful enough.
