This update is coming later than I had expected, but life got in the way and I've not brewed as much as I wanted the past few months.
After a few experiments and some equipment upgrades, I have settled on a ventilation setup for my brewery that meets my needs. What I am using is a 600cfm insert range hood mounted about 3 feet above my Brewzilla. That exhausts through a 4" duct to the outside wall vent that it shares with the dryer (the dryer and range hood attach to the outside vent with quick connect fittings so only one is ever attached at a time, takes less than a minute to switch from one to the other). With a few test runs and a couple of actual brews done, I have found that this will keep the steam out of the brewery/laundry room. After a hard 60 minute boil the relative humidity measured at the ceiling goes up only 2 percentage points, and I see no condensation buildup on anything. I think this works because the steam is being captured before it has a chance to spread out into the room, and the short run of duct from the blower to the outside (46") keeps the blower efficiency loss to a minimum. The best part is I was able to get the range hood for free from someone giving it away on Facebook marketplace.
