Aerotherm Heater/Fan This vintage item is both a fan and a heater. It has a two-setting switch on the side for fan or heat mode. When in heat mode a coil is activated and the fan blows heat. The unit works but makes a bit of noise when running, which adds to it's allure. .Approximately 13" tall x 11" wide x 5.5" deep .Retro look in a tan/brown color. There is some wear on the finish. It still has the original cloth cord.
