I need to replace a good quality fan that has served us well for many
years. I want to get a fan that:
Moves a lot of air
Will last a long time
Is reasonably quiet for the work it does
Lowest reasonable power consumption

The fan should be approximately 22-24" or so wide. In case it helps, you
can see the fan that is being replaced at: http://j7000.com/e/fan.jpg

Are there particularly good models and/or brands I should consider? Info
on where they are sold would also be helpful.

Thanks.
