Call me crazy, but I purchased this industrial exhaust fan for its sculptural beauty and rusty patina. I'm not sure what it's made from. New ones are stainless steel, but not sure if this one is because it wouldn't rust, right? Anyhow, I thought it would make a cool sculpture for someone with a large space or could be an interested garden sculpture. The top where it connects to the round thing is severed as you can see in last photo. I'm not sure if it is suppose to be or not.
