This is a lightly used centrifugal exhaust fan. I had 24 of them that running 24/7 for a couple of months and they have been sitting idle for some timed now. I cannot guarantee they will work after they leave my care, but I can guarantee that when I got them down and cleaned them up, they ran fine. They are all single speed fans that are set up to either run at full speed, or not at all. No speed controller is included.
