i can't find 42" for pana nami in website

also, the more blades the better? i google it and they said for aesthetic purposes

Sorry, is 56.

Anyone happen to use Alpha Cosa CX699?
The remote original is broken, and I bought another one online..however it's not working.

Rather than buying another one, can anyone using this fan to share the remote control model and photo?

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)..

hi sifu, is DC fan really save more energy? cause AC cheaper a lot
any cons for DC fan beside more expensive? some claim DC fan lighter, is it true

plan to replace my ceiling fan in living room soon

DC fan definitely saves energy but the energy usage of ceiling fan isn't really an issue even if run 24/7 compared to say aircond. That's why the cheap regulator fans are AC and still 5 star energy, you need DC to run all the fancy features like Yuragi and 9 speed etc.
The con for DC is that there's no point paying for all those extra features like Yuragi etc if you're not gonna use it, and most people don't.

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 just realize my Cosa is 3 speeds while the new model is 4 speeds. Hence need to ask around ....

KDK released new DC fans (DC-4 series K14DG-TE) 140cm/56") recently retailing around rm500-rm510 each. Anyone bought? https://www.kdk.com.my/product/k14te-dg/

doesn't look like ABS blades to me

Sensa 4 / 5 might be a better buy

Good day,

I changed the KDK K14Y9 board 3 months ago but the buzzing came back shortly after. Also changing the board kind of wrecked the remote contact or something. The other KDK is an old one but it is crooked and it's making lots of noise. I could just straighten it out but considering the power consumption...

I'm not an engineer but my guess is that the newer AC ceiling fans (e.g. got one KDK K15v0 recently), are rated 5 star energy but they consume 75w at max speeds.

I have the KDK K15v0 and it's good enough at speed 3 out of 5. It's also very big and I'm wondering if I can buy smaller fins and fit it out rather than changing the whole fan?. From the K12v0 range or something. Can I do that? Or the Panasonic equivalent? The reason is because it's cutting into my lights. I've removed the two light bulbs closest to the fan but now it's a waste.

Just like my Deka F5DC is good enough at speed 1 out of 5. Even speed 3 is enough. From what I've read DC can regulate electricity so that means at these low speeds it uses less electricity.

Compared to my NSB Asta last time with only high or low, low was practically non-existent. Heavy and I think this is why the fan motor couldn't sustain it and died years ago. It was just eating electricity while trying to move.

Hmm.. can enlighten me please what is the benefit of abs blade vs metal ones?

Thanks for sharing the info. I'm also surveying for remote controlled ceiling fans.

Currently I'm using Pana/KDK but those older basic type which the PCB will cost about RM60 to replace, and need to do so once every few years else certain speed will not run.

I see now you are saying that better not to go with the Bayu series but to get Nami instead. May I know is it due to this PCB reliability issue? Or there are any other considerations?

Thanks

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

Finally they have a white colour fan.

just bought DC4 - K14TE-DG (Black)

any1 have experience with this? anything i need to know..

no going back dy, cuz bought 6 nos for Rm489+- each.

You shall share your experience with us since bought. This is new model from KDK?

sales person inform me yes, new model. if not mistaken the cheapest DC motor from KDK.

I saw they even advertised this model in the digital billboard.

Sure, will share once installed..now still working on the ceiling, wiring, sockets and switches.

Yes from my search new model and cheapest KDK DC motor. Hope it is good model.

this one got those pcb like in the AC models where need to be replaced after a few years' usage or not?
