Good catch, it is an Elicent AXC 200B which *is* rated for ~700cfm, I believe I got that confused with the cfm rating of the ductwork (~1200cfm ideally, like more like 1100cfm with the 90's and duct runs accounted for.) Which I will be pushing for with a second fan on the intake side to boost cfm, add in redundancy should one fan fail, and cut down the noise by running each at ~80%.

I've played with the idea of adapting in a 10" or 12" fan which would push 900-1200cfm but I can't reconcile that cost, any ductwork over 8" I have to deal with a distributor and that's also a huge pain.
