Alright so I know the manual requirements of a maximum of 2 bends and 8’. I’ve also read through the topics here but didn’t quite find what I was looking for.
I’m looking to extend my ventilation line with the addition of an in-line booster fan. In the photo, I’m thinking something like the red line. The X would be the booster fan which is roughly 8’ from the GF. It would be pushing air about another 16’ straight across the ceiling and out a vent. The booster fan is 6” and pushes 402CFM of air. I’m looking for feedback before I set it up because I’m not sure if this is really doable or is unsafe due to the length of the ventilation line.
