An Air Shadow ceiling fan spins its unusual retractable blades at the Fanimation antique fan museum in Zionsville, Indiana in a video by musician and fan enthusiast Dan “Spiffy” Neuman. Neuman regularly posts about interesting and rare fans on his Facebook page.
I demonstrate the Fanimation Air Shadow, a retractable blade ceiling fan based on the antique Bird Fan. This fan is in the lobby of Fanimation HQ.
A similar Air Shadow model with retractable blades and light fixtures is available on Amazon.
