I’ll throw out there that the fans that I’m using are essentially 140mm “muffin” fans designed for equipment cooling, and thus it’s easy to get bolt-on duct adapters for them. I have the parts and will be connecting them to duct the air from my booth out the window to the left of my setup. It’s not necessarily the most elegant design or solution, but it’s all off-the-shelf parts (except for my booth design, which is ridiculously simple) and will keep the solvent fumes out of the workshop.
Also, in case the subject might come up, here is a link to my post about fumes and in-line fans re: explosion proofing the hood. I know @ctruss53 was part of that conversation, but linking here for future reference.
