The hood is just a rectangular to round duct fitting from HD. Its just semi temporary till I find something better.
Did you ever update your hood? I have the same type of vortex fan, and used a foam hood like kal's early version. Getting a lot of moisture and dripping water in the opening in the hood that the fan is connected to. Fwiw, my fan is right above the hood. Wonder if that makes water collect more. ?
I dont want to spend $$$$ on a nice ss hood, so may make one and put a moisture channel like kal shows.
