An exceptional and highly collectible specimen of early 20th-century European industrial engineering, this rare double-sided “partners fan” was manufactured in Holland by E. Utrecht (Elektrotechnische Mechanische Industrie). Specifically designed to sit in the center of a shared desk to cool two professionals simultaneously, this heavy cast iron dual-headed fan boasts a striking Art Deco silhouette featuring opposing original brass blades and dual protective cages. Serving as a premier mechanical sculpture, this scarcity commands attention and makes an elite statement piece for an industrial loft, executive office, or advanced antique collection. I believe it is a 220v motor but may work on 120v as well. I have not tested not electrically, but mechanically everything seems to be fine. The item is offered in authentic antique condition showing expected cosmetic wear throughout, including minor surface scuffs, enamel loss on the cast iron base, and a rich, natural dark oxidation patina across the brass components that beautifully validates its nearly century-old history.
