KDK and Panasonic are from the same factory...KDK doesn't has factory in Malaysia. You may see the part inside the board or motor and found the Panasonic's model...The different between KDK and Panasonic are the color and design..Also you may have a look on the box for both fans, Panasonic has stated the factory's address while KDK didn't state any..
