Ah ... good idea. I don't have to be that close - 25% is probably good
enough (it's to calculate air change rate & if I get 4 when I calculated 5
(25% low), no big deal).

No..... NOO!!!

Measure the force, Measure the force!!!!!

Also, comparing specs may be easier said than done, as dimensions of the
squirrel cage itself matter, including the pitch of the fins. That, and say
1/2" off nominal diameters could be a biggie. Don't know how standard all
this is.
