This is a 2008 MUJI R-SA18 circulator fan, manufactured by Morita Denki as an OEM product. It has a simple and good design compared to recent MUJI products of the same type. I wiped it down briefly, but there's still some dust. Please disassemble and clean it if you're concerned. Made in 2010. Operation has been confirmed. Size: Approximately 30cm wide x 19cm deep x 30cm high. Includes a 3-speed wind power adjustment manual. No box.
