the orange blower, outputs into 3 ways?
can you take a closer pix of the blower and how it splits into 3?
I have a similar idea.... but your looks more "cost effective"

i used blowers like that in my previous job. the manual states keep childeren away from them and drapes. no lie.
lookup "flood restoration air mover"
you can rent them various places if you want to try em out.
