I've vented my kiln in similar ways before. Does anyone have issue with longevity of the fan? I had one before that ceased pretty early on in its life. Since then I've just moved towards a large a powerful window fan vent near by the kiln. It sucks 180CFM which is more than powerful enough to grab the heat and fume from the kiln. I don't have a picture. I've made a detailed build video here. Just trying to share a crazier unorthodox idea. It was much cheaper than your typical vent a kiln system. Thoughts?
