I'm posting here and not in workshops because my question is specifically about the noise of the attic fan. Does anyone have this model? What if I put a layer of carbon fiber on the blades so they don't flex or buzz? I'm limited to 16" diameter for this application, so a belt driven whole house fan won't work. This is more about creating a breeze through the house with dust management an added benefit. I'm making an exhaust fan in my shop and two of these side by side would perfectly fit.
