10"ish KDK exhaust fans in a friend's house

Sorry about the unoriginal audio. There was a copyrighted song playing when the video was recorded, so I had to remove it.
The first one, i'm not sure whether it's a KDK or not. The first one is in the kitchen and the second one is in the bathroom, which is through the door on the right. Sorry about the music- I recorded this before I cared about that kinda thing.
The kitchen one appears to be a replacement and looks to be from the early to mid 2000's. The bathroom one looks to be from the 90's.
