Is it advisable to buy a DC powered ceiling fan compared to AC powered? The reason why I’m interested to get DC powered is because it’s more energy saving and won’t be noisy or problematic in a long run compared to AC. The problem is, DC powered fans are twice the price..

One of my 5 blade Panasonic Bayu Ceiling Fan occasionally has loud humming sound when it spin. Any experienced forumer know why?

Its about 5 years old, got 3 similar fans in my house, only one has this issue.

Anyone got person to contact who can repair panasonic fan in ipoh?

I dont wanna call panasonic technician coz everytime I called them, they charge 100+ for a fix of less than 2 minute. Then few weeks later, the problem start. Around 3 times already i called and the problem always pop up few weeks later.

Problem is if I run at the maximum speed, it sounds like a motorboat engine. Mine is the remote controlled one, with 3 speed.

lift/slide up the cone cover, wd40 the bearing . add oil
[singer oil/engine oil/steering oil] any oil. l used cooking oil on mine. no sound now.

Guys, I am considering KDK Sensa 5 or Kaze series for my living room. Both are 60inch.

My ceiling height is 2.5meter.

Can give me any advise?

Thank you so much

Alpha fan Excel how reliable it is? And how it fares if compare to panasonic bayu 5??

based on my calculation, it takes me 5-7 years to offset the price different with electric bill. features i dont think i really appreciate what offered by Alpha due to mostly i use fan only without aircond.

Alpha 5-46W
Panasonic Bayu 21-69W
If compare at max speed = 69-46 = 23WpH x18h per day = 414W/Day
30days = 12.42kW
my home bill around RM40-50 per month.
so calculate with RM0.218 kWh, 0.218*12.42 = RM2.7 per month saving.
Alpha lets say RM600, and bayu RM300, 300/2.7 = 111.111/12months = 9.25years.

My preference for Bayu speed is 2, and Alpha is at least 3 to have same feel of wind flow.

So it is left with reliability, i am using a panasonic fan which is 15years already and it is still working, but with newer technology, remote control etc, can they last that long?
even with lifetime motor warranty by alpha, the PCB spoil also have to change fan if it is discontinued.

anyone mind to share experience or recommendation?
thanks

i ve been using Alpha since 2011 till now so far ok
only replace capacitor when the fan speed is weak

you are using dc motor?

yes
i think most of the ceiling fans are using DC

ic.. i dont know Alpha already produce DC fan since 2011.
most older ceiling fan are using AC.
Alpha price for AC fan is around 200++, DC fan around 500.

recently bought a mitsubishi ceiling fan RWS-P series for my living room..Alpha for two smaller rooms and kdk for master room..

trying to get different brands to try out.. hopefully it can last

i think your Alpha fan for 2 smaller rooms still working fine but u need to replace the capacitors when time come to change

thanks! will take note of that... hopefully it will be 5years later?

depends on your usage
if dun use frequently can last longer
