I’m using Alpha Alkova Dezi for all bedrooms in my house. The initial plan was to use KDK baby as well, but since my house comes with hook and the ceiling was a little bit to high, I went with Alpha since most of their model comes in standard height. So far, so good.

My previous rented house was installed with Deka fan, it started to make noise after few months being installed.

The same reason I bought Alpha instead of KDK. I did consider KDK, but their design was too boring. And they don’t have black to match my black & white theme.

Why not Alpha? You have plenty of choices to choose from with your budget and they come with good looking design.

They don't have the long history of KDK or Panasonic, but pretty established local brand with presence over 20 years++ in Malaysia.

Reliability wise, you have to ask around since every people have different story, but after sales service should be good since they are Malaysian based company. I was convinced to buy Alpha due to my sister's experience using Alpha in her house for the past 10 years. So far no major problem and the fans still running fine even though some of the parts has been replaced over the time. With proper care (like my sister & brother in law did), the fan still looks like brand new after 10 years, not even color faded. But then hers was glossy black colour, not white as white might become yellowish after some time.

Yeah. 10 years is pretty good for modern fan with electronics. I remember went to my sister’s house with my eyes wandering around looking for anything else that I should buy for my house, then my eyes stopped at the looks brand new fan, and ask her “eh, tukar kipas baru?”, and she replied no, it’s the old fan since day 1 she moved in. I was like, it looks like new, how is that even possible?

But then my sister and her husband are clean freak. So of course her fans are always clean hence can maintain the brand new look.

If you want nicer look, you can take a look at Aeratron. I have both Alpha and Aeratron in my house, Aeratron in low ceiling area (ground floor) and Alpha for normal ceiling height area. Just be careful when buying Aeratron because the have quality issue despite the price tag, make sure you check them thoroughly before accepting the product.

Why buy fan from sen heng though? Do they have some kind of promotion that make them cheaper than usual places?

The usual shop is selling KDK sensa 4 for around RM500, how much is the price in Senheng?

And for quite reliable fan like KDK and Panasonic, they would not fail within 2 years, so extra 1 year warranty is a waste. If you happened to get a lemon unit, they will fail within few weeks or few months top.

The price I was quoted for KDK Sensa last year was RM492. It's up to you if extra RM91 worth the peace of mind. Personally, I would pay extra (for warranty) for something with questionable quality, but not the reliable ones.

If the fan is only to cover the living hall, should be good enough. Most of my bedrooms, 10.5'x12' size are using 42 inch fan and the airflow was good enough at half the full speed.

You're contractor is right about the disco effect (stroboscopic effect). If you want to be sure, just draw a scale drawing of the down light position, fan position (and height) and projected light beam (using beam angle from manufacturer's data) and see whether the beam did cut the blade or not.

Looking at the dimension of your living hall, you should be able to use good looking alpha fan without having to change the rod. My bedrooms are smaller than your living room and I use 42" alpha with the rod that comes with it and there was no noticeable strobbing.

Well. Don't blame me if it doesn't work for you

Different model produces different airflow, it could end up that the 42" you bought doesn't produce the same result as mine too..

Like ceo684 windless bayu is 56" but probably generating wind of 12" fan only.

Alpha Alkova Dezi. Both 42" (in all smaller rooms & upstairs living hall) and 56" (for master bedroom).

When I switch on the AC I only use at speed 1 or 2 out of 8.

You might want to add Aeratron in your list too. They have 43" + short pipe.

I used them in my living hall & kitchen where the ceiling height are quite low (9' 2" and 8' 6" respectively, since I want to hide all beams and I don't want my KC to look too tall)

If you don't have enough budget, I would suggest you put up plaster ceiling first (to cover the beam), then buy affordable short piped fan like KDK Baby first, and upgrade later when you saved enough. It is easier to change fan than to change your ceiling

Btw, what would be the ceiling height if you cover the beam? One of my bedroom is with 9' high ceiling, and Alpha Alkova Dezi looks fine in it. Doesn't look too low to me.

Another way to do it is to let the fan remain at the slab and do cove box up along the perimeter of the wall. That way you light will be positioned lower relative to the fan itself. With proper planning of the light position, you could probably use a bigger fan.

And your living hall isn’t exactly that small. From the plan i think is should be around 22-23’ length. With proper luminance & and light wall colour, the hall would still look big even with lower ceiling. Try measure the exact floor to beam height. I think 8’ 10” should still be okay (assuming your beam is 14” like mine).

I think every home owner should have at least told the plaster ceiling contractor beforehand what do they want to hang on the ceiling including fan, pendant light, and also curtain so that the contractor can install proper plate or timber strip attached to the slab to support the weight. I did plan everything for my house but still I forgot to plan for my ceiling to floor curtain. End up need to attach the curtain railing to the wall.

Your hall width is only 122”. If you follow the manufacturer’s guide of having 3’ gap from tip of the blade to the wall, you will end up with 50” available space for ceiling fan. If you plan to go bigger then recommended, then I think 56” should be the max already.

And better to have 2 smaller fans, one in living area and one for dining area. Otherwise you would have nightmare planning for the downlight positioning.

Use this

Trigo Calculator

Key in this

Angle B = Downlight beam angle divide by 2 (if beam angle 110, then put 55)
Side a = Fan height from ceiling

You will get "Side b" which is the minimum gap from tip of the blade to the centre of the downlight.

Then you can size your fan.

Probably better to give extra 2-3" gap for "safety".

Any unit would do, feet, inch, cm, mm all can. Looking at the result you get, I think you key in the wrong height. The fan height is the actual fan height from one end of the rod, to the lowest part of the fan. Not from ceiling to fan height.

I suggest to put measurement in inch or cm, for easy reading. And whatever result translated in in the same measurement unit.

there on top-right, "Beam angle=120 degree"
