SMC K48 and DEMC vintage industrial ceiling fans at the Jumpstart learning center.

UPDATE: THE CENTER MOVED AND LEFT THE FANS BEHIND. I DO NOT KNOW WHAT HAS HAPPENED TO THE BUILDING AND THE FANS IN IT. The new building has some KDK/Panasonic orbit fans on the covered roof deck.
The two vintage fans are the DEMCs. The middle one seems 56" and the end one 48". The teacher thought the 56" DEMC didn't work, but the cheap control was missing its key. I think the controls were replaced during a renovation of some sort, as they look to be new SMC controls.
