there is some truth to it for more blades better
fewer blades (3 bladed) need higher rpm to run
For same airflow the 5 blade can run slower rpm compared to 4 bladed
case in point comparing these
https://www.kdk.com.my/product/k14xz-pbr/
vs
https://www.kdk.com.my/product/k14yz-pbr/

the 4 bladed is 102-196rpm
the 5 bladed is 95-183rpm

power consumption about the same coz more blade heavier to turn.

TLDR, any 54-56-60in about same airflow one lah whether it has 3-4-5 blades. Its more on aesthetic choice.

60in regulator with 3 blade, because of higher angular velocity of a bigger diameter produces the most wind at lowest cost, lowest maintenance cos the regulator house the capacitors and RM32 every decade to replace *very user servicable too*. whereas remote fan all on PCB and replacement need some work.

However for remote fan go for the KDK Vtouch or KDK Sensa, likewise for Pana also look at RM400 series up (Nami)
do not get the Bayoo series. many lemon.
Rm300 one if new model OK. as this is the cheapest remote series-new model new dies ok the plastic still in tolerance. after many years of use the die lose tolerance and a lot of funny stuff happen as QC is close two eyes on the cheap series.

Try contacting Alpha directly? IIRC, things from Alpha, Joven they do sell spare parts (even for their WH)..

Not true that yuragi need DC. Sensa 4 AC motor also got yuragi already.
Ceiling fan is cheap to run.

As a feature, Yuragi nicer to sleep with/chill under (like living room) if you just rely on fan (no AC). feel like natural breeze coz got speed variation.

Fundamentally no point to go for RM500 range 4-blade (Sensa 4) as its still the same ABS blade as the RM4xx Vtouch Jr ABS 4-blade (both have Yuragi)

However between RM300 range of basic metal blade vs RM400 range for ABS blade there's a big difference.
at this juncture, the ABS blade is the whole point of it and is well worth the extra 100.

I bought a Bayoo in 2014 was OK
I bought another one in 2018. Kept until got my keys at 2019. The horrors. At full speed it couldn't even blow off tissue paper on the table hence the nickname windless wonder. I alr install uninstall from living room to master bedroom to store room all also same issue. Didn't use it much at all. Sold off half price to a forumer here (if you read back this thread) and bought a new model KDK. Bliss

Consider a marvelous invention called a wall fan. https://www.kdk.com.my/product/kc-4gr/
The wind blown by it is really "tubular" like a light beam (for this model).

1. No diff
2. No diff, its LPPL (more blade slightly lower rpm) between 4 & 5
3. KDK Sensa 4 for bedroom, living room either Sensa 4 or Vtouch Jr, small room just take the remote fan about RM320 range from KDK.
3.1 Don't bother saving the few bucks on Pana
3.2 Same factory but diff process
3.3 Forget anything sounds like DIKU

I bought one, didn't manage to use it due to lacklustre wind, sold "Lightly used with box" for half price because this particular model is lemon model.
Or in summary = "Regret"

If I had to pay myself for installation and uninstallation [from living room - MBR - storeroom] I already rugi more than the fan price itself

Yeah I bought in 2018, installed in 2019 when i got keys, then really never used much as work in progress
Sold off in 2021 or 2022

I got the KDK equivalent Z-series (i think 2021 release) with the narrow stem cup and it has worked perfectly (tissue on table will get blown off at all speeds)

whereas the 2018 Bayu dunno what happen i put max speed also no effect to the tissue paper on table. can never blow off.

Wall fan, that KDK remote wall fan will be perfect, can be pointed at wherever and air movement is damn good due to the blade design.

KDK K11Z1-ES (110cm/44”)

Same factory, different licensing and CR process, diff production line. Proton Saga vs Mitsu Lancer.
Krek krek noise, max speed does nothing, no wind, tissue cannot blow off the table at max speed even if left to run for 30 mins.
Already uninstall and reinstall all over my apartment.
The RM15 savings not worth it. Replaced with a Z series KDK when it was newly launched and tissues can't stay on the table TCO, after minus off the losses from that Bayu 4 sale and new KDK Z series can already buy a Sensa 4 from the beginning.. even a V touch jr would have been cheaper. Haven't count my own "installation fees" if I had to pay RM80 per trip imagine how much alr.

wall fan for long and narrow better, ceiling fan in too small a place also don't work well.

The area right below the fan should be ok. But if you want to move lots of air in a narrow long rectangular space consider using a wall fan the KC-4GR. That blows a lot of air like a tube.

Sensa 4 👍 using for living room too.

Buying on price alone is the worst thing.
I am very glad to have sold off that exact same model at a loss of half price because it was a windless wonder.

Never ever.
I only spec KDK in my house and there has been no issues.


There has been a lot of mention of the Bayoo 4 lemon in this very thread.

KDK Vtouch Jr, else if more budget, Sensa 4

Based on the no-hook and very limited space, a ceiling fan would not really fit well unless you get a short shaft one. It would be more useful to install a wall fan for ventilation. KDK KC-4GR

Find rubbish bin and terbalik the fan motor.
Mount the blades except one, on ground.
Climb ladder.
Mount the fan on hook.
Finally install the last blade in the air.

Trying to struggle with all blades in the air and the fan keep rotating everywhere hitting your head is not a good idea. The n-1 arrangement allows you enough room to struggle with the rubber bung and the bolt.

Just don't mount the plastic tupperware cup so close to the ceiling that it scrapes.

Tolerances in QC. Metal blade model tend to have looser tolerances. You can check the gram weight stickers on the blades.

Mainly how annoying it is when it bangs into your head.

Not much difference. Less use of electric kettle will be more saving unless you run the fans 24/7 in mamak stall.

Bayu dont waste the money, add few bucks for KDK. Avoid the hassle.

Sometimes the most basic solution to keep a hot room exacerbated by high powered desktops cool, is to mount an exhaust fan on the window and keep it running 24/7

Blardy fan at max speed is so weak that there's no wind at all. Can't even blow off a tissue paper on the table even if you leave the fan running for hours on max speed.

Sold off and put in a KDK 4 blade remote (the cheap model at 300 bucks range) at mid speed only - the tissue dunno fly where in mere seconds.

There’s some blade tech involved. If budget ok for 400+ range the Vtouch jr with abs blade is awesome

Same factory can also produce Lexus and Toyota.

That one time I bought the remote Bayu 4 brand new from a lighting shop in Puchong is the time I regretted the most. Lemon unit can't even blow tissue off a table at max speed. Already installed and uninstalled the same fan from living room, medium room, and small room, and actually never used it more than a month total runtime. Finally sold it cheaper than half price to a forumer here.

I bought another KDK remote and that thing blows tissue easily even on speed 2.

I swore not to get another Pana in my life; but I had the chance to get a free Pana remote fan which was running slow and the prev owner didn't bother to repair (OLD model silver colour type) which needed a PCB board replacement, I swapped the PCB out for 40 bucks (replacement from spee) and it works again.
