Getting 3 normal-sized fans for living room, dinning area and master bedroom; and 2 baby-fans for study/working room and baby/guest room.

Current decisions are:
normal-sized fans = KDK 5 blade fan K14Y9-GY
baby-fans = Deka Baby 6 + Deka Baby G

I'm choosing KDK due high confidence and experience using it. However, it's too bad that I could not choose its baby fan as my rooms are covered by (flat) plaster ceiling with hook, not suitable for KDK baby fan.

Deka is chosen by random reading here and there. Still open to other alternatives such as alpha, etc... please comment

My initial plan was to get KDK fans (K14X8-GY or K14Y9-GY) but I have received many comments (including my main contractor) that I should not because my ceiling height is only 8' 8" which is too low.

1. How true is that? The height of K14X8-GY & K14Y9-GY are 375mm (~1'3") and 466.8mm (1'7"). The recommended height told is >7' from floor to the fans

2. What are other recommended brands and models? Reliability is the priority. (of course budget is one of the priorities too)

I have checked, both KDK and Panasonic models are around 380mm (around 14 inches) which barely leave 7 ft of space for my 8 ft 8 inches ceiling height.

Any member here has experience or knowledge if it is fine to get these fans?

Also, besides KDK & Panasonic, which alternative brands out there with shorter dimension, excluding baby fans?
