Some baby fan for low ceiling doesn't use hooks to mount. But they need you to drill 4 holes - and insert anchor bolts into the holes.

I removed a kronos 5 blade as it failed on me.
Heavy to install as compared to the competitors P and K - and the metal concealer cup cannot be taken off the rod and they don't deburr the edges of that concealer cup .

U try reassign the blades to different config, like now is ABC try ACB / ABCD You try ACDB.

Assuming your fan is operating fine and has no faulty motor or bearing (meaning that when its set to speed 1/2 it still works and not just for show turning slowlyyyyyyyy) it should only take like ~80W

I would suggest these questions since all fans are not created equal
1. Ceiling height - Standard Apartment/condo or low ceiling flat or duplex/very high ceiling
2. Clearance for blades - if wall/cabinet/wires for lighting is nearby u need to consider.
3. Fan size - Standard 3 bladed fan is 150cm/60" dia, more pretty ones are usually 140cm/54" dia. There's also huge fans suited for conference hall/event hall/hotel lobby.
4. Normal fan enough, or yuragi function preferred
5. Expected budget - 150/pc 300/pc 450/pc 700/pc or money no object
6. Room temperature (performance consideration) - choice of energy saving or maximum performance (airflow) required

KDK.

It's used to fit a fan into super small room/toilet with narrow space/low cost flat 8' ceiling height/cabinet blocking a full size fan.

No problem as long as the fan is attached to something solid (e.g. fan hook). The plaster ceiling gypsum board doesn't hold weight.

See the cfm produced, whichever higher then take that one.

I had a 4 blade (metal blade, remote) Pana Bayoo 4 that didn't do much wind. It is good for rooms where a wall is beside the fan. Open space no good.
Fan motor power: (Low) 20W (High) 68W
Fan motor HP: 0.10

I took it down and bought a KDK Vtouch Jr, 4 blade (ABS blade) wah instantly got the feels.
Fan motor power : Low 19.5W High 85W
Fan motor HP : 0.13


Thing is cheaper fan come with smaller motor. Cannot compare kancil with inspira lol.
Also the KDK being a midrange model also come with ball joint.
The cheaper Bayoo 4 doesnt have a ball joint.
KDK got Ball joint = close to 0 vibration and super easy installation. The blades attach much better with the KDK.

All AC fans.
AC motor more tahan for long term.
DC motor used for specialty application like high starting torque (assembly line).. fan blades only no need high torque la
The 200+ bucks more for DC fans can easily pay for many years of electricity difference from AC fans.

Switching rotation direction not really much use here, as our climate is hot 365 days a year.. same as we don't need a heater function in aircon..

1. You won't go wrong with KDK V touch. Mitsu not really fan specialist. Pana one, if you have frens working inside mfg factory, they cut cost like crazy wherever they can.
1.1 The difference between 56" and 60" is not so much as the 4" but motor size (0.10W vs 0.13W motor) really makes a big diff on the wind. I have the V Touch Junior K14Y2 (140cm/ 56″) comparing with Bayoo 4, I fart also stronger than the bayoo 4.

2. Get the KDK K14Y5-GY over the Bayoo 5.
https://www.kdk.com.my/wp-content/uploads/2015/09/K14Y5.pdf - see page 9 fan blade - the fan blade hole for the hook is punch out from the solid metal of the blade, which is proper.

Whereas Bayoo 4 blade [and my physical safety] is depending on a wire attached to the fan blade to hang on for dear life. as their safety "hole" is actually one whole longkang from the edge of the blade with only the wire acting as "seatbelt".

Sure thing. Between 4 blade (K14X5-GY) and 5 blade (K14Y5-GY) should be similar wind as their CFM rating is the same. More towards aesthetics whether 4 blade or 5 blade suits your taste.

This is almost triple the weight of a normal fan (6-7kg), apparently the mondo is 17kg. Can ask them to secure using L angle bar or using bolt-and-nut thru the wood (ask them use 2x4" or better)

1.
Between 4/5 blade they should have similar dB (noise rating) of the KDK K14Y5-GY / K14X5-GY. Residential use fan won't make lots of noise unlike industrial fan (think mamak stall extractor).

2. I think that applies to high speed >1000 rpm, when the metal bend/flex as turbulence from the air causes it to resonate.

3.
At the max rpm (200-ish rpm) noise should be silent enough, not terribly noisy. I think paper flying around will be the one making more noise

I think the lack of CFM rating for Rubine makes it hard for actual CFM comparison; but based on the manual, 85W AC motor is comparable to v touch junior (also 85W); this should have enough wind for the smaller rooms.

As an experiment can split half half to see which brand is more lasting

You can use the short one - just spray with spray can to the brown you want

I strongly advise against getting a windless Bayu 4 if buying new.

Sensa 4 when shopee card discount was only like RM30-ish more than a Vtouch Junior 4 blade
Both also got yuragi function (sensa and vtouch junior)
Sensa got more gearing (more selectable speeds)

Who want to buy a Bayu 4 I can sell 30% off from lowest price on shopee or lapsapda
fullset with box, warranty card
fan like new condition
runtime in total less than 7 days worth of usage.
Need to free the space on fan hook to buy another KDK

Hmm so far my experience was very good with new old stock K14Z9 should have cleaned out the warehouse sale stock
Then I bought 2 more V touch junior K14Y5
Then another Sensa 4 current model K14ZW - only this one still haven't installed yet

For me I don't mind coz fans are very cheap to run as compared to any aircon unit.
Nothing ruins the day better than a 5* windless fan even at max speed.
I've already taken down that fan twice and installed thrice - living room, medium room, and finally just stuck it at the smallest room.

Where I bought fans from.. all over the place..mostly shopee online purchase, couple units were retail

K14Z9 - EOL Sensa 4 - Warehouse sale - only paid RM249 for an awesome quiet fan with yuragi function. Granted old model but its still BNIB condition.

Bayu 4 - Retail experience - Regretting the RM270 I spent on it.

Vtouch Junior - Retail experience. And my most expensive fan - was at Aeon but had CC vouchers so its heavily discounted per se. Listed at 490.
Vtouch Jr cost 403 on shopee.

K14ZW Sensa 4 only cost 459 after shopee CC voucher (listed at 515, min spend 500 get 80 off, which meant I could not buy another Vtouch junior to get that discount).



Other notes
KDK fans have lots of foam all round as protection so it will survive logistics handling very well. Plus they're relatively lightweight for that size of box.
It is only aircon that is heavy but the foam only covers the ends that the center part of the box always gets crushed in transit.

You can try to go around electrical shop to see if they can give a better deal.
Personally, I hate haggling with retail shop as the "open price" amount quoted is easily 10% higher than online price with shipping when I bought my fridge.
They opened price at 2.5k when the online price was 2.1x-2.2x k (inclusive of delivery). I nego down to 2.4k with a Sat morning delivery guarantee (which went very well 8.50am already arrived at guardhouse). Staying in poorfag officeslave class of high rise have to take care of delivery hours window of opportunity too.

That time I had no choice but to get from retail because only can deliver on Sat morning and the online seller can only commit weekday afternoon/evenings which also costs me a day of work (need to take leave).

Both are equally good (Sensa or Vtouch junior). If you have no clearance issues, can get the 150cm fans those give more wind as compared to the 140cm ones. Or maybe living hall put nicer fan the rooms can skimp a bit.
If design is not a priority the basic 3 blade one with controller box is actually a very good fan (pushes 8122cfm) for the price.

140cm ones.. the better ones push 7900 cfm
The so called energy efficient (cut cost models) motors push 7400-7500 cfm only

The CC voucher was a SCB partnership with Shopee on home appliances category. Once in awhile they have it, not an ongoing evergreen promo though.

But even with the same diameter, there are weaker motors just to comply with 5* ratings, case in point bayoo4 vs any other higher priced KDK (vtouch junior/sensa 4), cfm is reduced because of weak motor 75xx vs 79xx cfm
