Dear all.

I need to purchase ceiling fan for my new house but i am lacking knowledge about it. I hope sifu at here can give me some advice.

1.) I have shortlist 3 model for my living room KDK V touch, Nami 5 and Mitsubishi C56-RW5-P SYGY. May i know which one is better and does 60" blade is really better then 56" a lot?
2.) For other all small area i am currently shortlist 4 model, KDK K14Y5-GY, Panasonic Bayu 5, Alpha AF20-5B/56 and Rubine RCF-PICCO201-5B-GM. Can advice which one should i go?

Appreciate for all the advice. Thank You.

Thanks bro for your advice then i will go for KDK for living room.

For those small fans today i go the shop and have a look. As you say KDK K14Y5-GY is good and Rubine RCF-PICCO201-5B-GM also impress me. Panasonic and Alpha both out now.

Sorry 1 last question. if for KDK K14Y5-GY 4 blade and 5 blade wind will different so much? Thank You

Dear Master Sifu, Thank you so much for the article you share. From what i study
1.) 4 blades is optimum but depend on motor power also. In this case how we know the power of K14Y5-GY (69 watts) is good for 4 blades or 5 blades? If i read the rubine fan manual it say it motor is 85 watts but with 5 blades in this case is that rubine is better?
2.) For Noise wood < plastic < metal but air flow is Metal > plastic > wood. If room all put thet K14Y5-GY then will be very noisy although it can generate more wind? because the blade is metal.
3.) Finally if i not mistaken blade pitch & blade angle is same things. KDK K14Y5-GY the blade look like flat. That mean it generate less air flow?

Actually i am very firm that 1 V-touch (if got budget senza) for living room but for other 6 rooms. I been thinking shall i should put all egg in 1 basket that mean all 6 pcs fan also buy KDK K14Y5-GY or half KDK and half rubine.

I been try searching rubine fan review but seem like very less. This is the rubine product details can you give me some advice?

Dear All Sifu,

I wish to ask some questions regarding fan slow after sometime. I aware of this mostly cause by capacitor issue.

I move in my house on 2020, during that time total fan i purchase is 7pcs. (3 from Panasonic, 3 from KDK and 1 from Rubine) All is AC motor fan. Now the Rubine already moving very slow while other 6pcs still good.

I wish to ask
1) It is Panasonic and KDK fan don't have this capacitor issue? or it will still happen only it can last longer.
2) Nowadays many ceiling fan with DC motor also is affordable price. Does DC motor fan also will having this capacitor issue? Because as i know DC motor not require capacitor anymore? But DC motor fan will have any other drawback compare AC motor fan?

Thank you in advance for any advice.
