KDK & Panasonic industrial ceiling fans | Shorts 

These fans are located in a minimarket.
You can see KDK WZ56Ps, Panasonic F-56MZ2s, and Panasonic F-EY1511s. One of the 56MZs was noisy, and no F-EY1511s spin as fast as the other two models. Even if this (except the 56MZs) are everyday fans, you don't see many of them in a minimarket everyday!
Enjoy!
