Anyone use them? They list CFM number a lot higher then other, and less amp draw.

3000cfm 16" S blade fans with a 10amp draw, when others are 2100cfm and 17 amps. They are cheaper too.... sounds to good to be true?
Iver never looked into whats out there for a universal electric fan, dont wnat to find out theirs something up with there specs?

Evey fan mfg. rates the cfm differently, some flow with no restrictions and others flow with a radiator in front of them. The easest way to look at fan cfm is the amp rating, figure somewhere between 100-110 cfm per amp.

so at 10 amps, you'd be looking at 1000-1100 CFM
