I successfully sold off my "windless" 2018 Pana Bayu 4 metal blade and replaced it with a similar class of 2021 KDK K14XZ metal blade. Now my tissue paper can fly off the table in the same room

Between KDK vs Pana yes they come out the same factory but built to different standards (diff assy line)..KDK line is tasked w/assemble only as per spec, cannot modify w/o approval from JP principal..so the components are constant for that model.
Whereas for Pana..they hold the licence..they own the factory..they have full rights to cost cutting. The few bucks delta between KDK vs Pana is NOT worth saving. It look similar on the outside..but the insides eg the motor used, that is a nice spot to cut corners. They are similar class (design n price range); but I would NOT call them identical.

For the car porch I think having a wall fan KC-4GR to blow out a tube of hot air will cool you down better. Because of this "tube" it gets rid of hot air trapped.. like an exhaust fan that can swivel.
Ceiling fan recirc the hot air from top (near the ceiling) to blow downwards. It may not cool down much.
If I understand correct, best to go for the KDK variant than the Panasonic variant? Sensa 5 is priced cheaper than the Panasonic option (leaning towards the Sensa 5).
Somehow I don't quite like the wall fan design at my car porch area, so gonna stick to ceiling.
However am hunting a wall mount for my laundry area

this 20" model caught my attention definitely. Panasonic F-MU50Y.
