Amazingâ?¦..Zandor, I was just imagining some kind of sheetmetal/ducting that could pivot, between directing exhaust outdoors or into the room. So far Iâ??ve put off the challenge of sitting down to design one, mostly because it didnâ??t seem very approachable (Iâ??m not familiar with any swinging-door ducting, then attaching a motor somehowâ?¦.).
Well, I guess thatâ??s why we read these forumsâ?¦ Do you have a link to a motorized damper???
