XXWHF24DDKD - 24-inch Direct Drive Whole House Fan Blade Assembly is rated 4.7 out of 5 by 3.
Rated 5 out of 5 by from Much better than the original The hub holding the fan blades on my whole house fan cracked after a year or so of use. I welded up the crack and it ran for another year before cracking again. I welded it again, but figured I'd better just get a replacement this time. This one is much beefier than the original. I don't think there is any way that this one will crack on the hub spoke like the last one. For some reason it also seems a little quieter, but that is a little hard to quantify.
