You may want to really think about any Byron products. While they led the way many years ago, by todays standards they are quite inferior. There fan system is simple, but a big mess to run and the lack of parts is a problem. There are a lot of other fan products which are more relable and up to date.
Remember the money you may save at the purchase will be short lived!!!!
I speak from lots of experience. Good and bad !!!
