Redoing my venting in my lampwork studio and would like to make a funnel ventilation system. I've been sifting through old threads but many of the links are broken and some of the information is outdated so I thought I would open it up again. If there is some good schematics and/or advice that is current regarding how to put in a funnel ventilation system, I would appreciate being pointed in the right direction. I've seen Whit Slemmon's excellent version, however I don't have enough room to put a fan on the outside + I live in temperatures that get to -40 in the winter. Ideally, I would like to keep the fan inside so any suggestions for a powerful, compact and quiet fan would be appreciated. Would love to see current photos of funnel ventilation systems that you're happy with too.
Thanks,
Carrie
