This is a KDK Model E30KT 12 Inch oscillating fan. Like most Japanese desigined fans, is has a steep blade pitch. A steeper blade pitch allows the fan to run more slowly and quietly while still moving a good amount of air.

Looks just like my F-1205, just has a different front grille badge and a different sticker plate on the base.
