Most fan cfm numbers are totally bogus.

Until you get up into the 2000 cfm range (and the associated big $$$) most of the numbers listed for a ventilation fan are pretty much twice or three times what they actually deliver if that.

I used the fan from my old house furnace rated for 100,000 btu for my 2100 square foot, 150 year old house.
It's a squirrel cage fan about a foot across and I am not real certain that it moves air fast enough or with the volume as I would prefer unless I decide to enclose the back and sides.
