I don't know anything at all about hooking up a range hood.
But there would be no distance either way, just gonna park my workbench right up against an outside wall and the vent system will go straight through the wall.
The Glasscraft hood looked easiest. It stated it was specifically for lampworking.
It looked like you just cut a hole in wall, fitted mechanism in and propped the suction part up on your tabletop or right above it, whatever, and it did it's thing.
I checked out the links but I still don't know how to use/install those in line blower things
