You are bidding on a 1950's vintage Atlas Aire 20" Window Fan. It has a 2 speed reversible pushbutton control on the side. I bought this at a yard sale some time in the early 80's and it has done many years of duty in my parents attic window. We sold that house 2 years ago and i am cleaning out. It never had side wing panels so a friend of mine who runs a steel and iron shop made me a pair from a pattern from another Atlas Aire fan. The motor works fine and the two tone aqua is in good shape (i was able to match the aqua color to paint the side panels. The silver blade shown is original and it has started vibrating so i am including a 20" Lasko blade as well which runs on the fan well.Shipping is via UPS and includes insurance up to $100 and i do not charge for packing. If you email me your zip code i will estimate shipping for you. This fan is not a lightweight, it is heavy and the wing panels are heavy guage steel.
