Hi, I see you live in the US so man you have a vast choice of extraction fans and trunking available to you there.
Very popular are the “in-line duct fans” with cfm values that are unbelievable and at good price point, shipping, if any, would certainly be cheaper and the wait less.
In my machines I run indipendant fans and exhausts, and the cubic capacity of the machine working space is just on 1.3 m3. I wanted the air to change quickly so there was a minimum of time between the end of the job and opening the top, so I went for a fan that would chance the 1.3m3 in just about 2 second.
So I needed a fan that was for 1080 m3/h
I will attach some of the choices I had as an image
Hope it helps
Something definately to consider especially if you are in a residential area is the noise some of the bigger fans make… So please ask for a db level and try to get something that makes the same noise to really understand the impact 
In duct can be very quiet
