CMC, Panasonic, and National industrial ceiling fans

Located in a grand mosque.
Here are some CMC, National, and Panasonic industrial ceiling fans. This is my 2nd visit, and a fan has changed since last time. There used to be another Panasonic F-56MZ2, but it has been replaced with the 1511 on the thumbnail. All of the fans were off because it wasn't prayer time.
Enjoy!
