Somewhat experienced, need ventilazation advice

[wman44]

I need to hook up different exaust lines to the same ductwork. I have 2
fans, one a sunleaves wind tunnel, the other
an industrial centrifugal fan. I need advice on how to make the most
effecient system that only has ONE vent hole.
I know the industrial moves more air. Any help would be appreciated. I need
an HVAC guy perhaps

There are lots of way's you can hook up an exhaust thru a single portal.


It's the exact size of the exhaust and where your drawing it from that pose questions.


None of which you have answered.

either I'm stupid or you are. I'm guessing me...so please explain more. You want to hook everything up so it's daisy chained, but you dont know how to do that? Stick one end into the other and zip tie or O-clap shut. How hard is that? I must be stupid.

I suppose there are just a few things to watch for:

1, make sure air flow is all going same direction
2. i dont think it matters one way or another if your pulling or pushing the air, so if there is a question about whether to install the fan in one section or another it doesnt matter to air flow.
3. draw cool air from outside, pass through all hoods, push air back outside.

What's to know? You have two fans, use the largest first, use as much ducting as possible before airflow drops, then add in new fan for a boost to boost flow again for the rest of the run.
