What is the truth about amperage vs CFM out of an electric fan?
I am still looking for the electric fans that I am planning on putting on the 72. Problem is that there is a zillion and one options with everyone saying theirs is the best. This is STRICTLY about electric fans, do not want to get started down the mechanical fan vs electric fan discussion again. The biggest question is this: Company A says that their 16 inch fan puts out 3600 CFM while only pulling 10 amps. Company B says that their 14 inch fan puts out 1500 CFM but pulls 18 amps. Does design alone of blades etc really make that huge of a difference that a fan will put out over double the CFM and yet pull nearly half less amps? And then (I am afraid to ask this question) what is the best fan blade design?
