It could be a Loft by Emerson or a Velocity by Craftmade.

If those aren't exactly what you're looking for, we have plenty of simple, clean fans on CeilingFan.com, in a variety of finishes with a variety of light options.

Let me know if you have any additional questions, I'd love to help with your ceiling fan purchase!

What kind of light track and track fixture is used here?

I read elsewhere that the fan was a "Westinghouse Lighting - 78614 Industrial Ceiling Fan." If you search 100k Living Room, you should find the picture. There was a man throwing a baby in the air and a lot of concern caused by the pic.
