Hi All,

Currently I am facing some headache due to having a low ceiling height of my house. From the plaster ceiling that I have clearance is only about 2.4m. To install a ceiling fan would be quite challenging as the length of the stem from the top to the blade level would be about 30cm.
To install the fan at plaster ceiling level, the height would be about 2.1m which might be rather dangerous as it is pretty low.

Now I am considering to install the Fan directly to the RC beam/slab. From the beam/slab to the plaster ceiling I probably have clearance of 30cm (for recessed housing for the lights). Meaning only a small portion of the stem will be exposed.
However I understand that by such, the wind produced from the fan will be reduced due to the blades being about 10cm to 15cm from the plaster ceiling.
For a reasonable clearance for fan blade to floor should be about 7ft meaning about 2.3m.

Is this a good way to achieve the clearance with safety?
I did consider using a stand fan but priority is still for the ceiling fan due to furniture layout.

Please advise or if there are better way to connect the ceiling fan to provide safety clearance.
I have attached a sketch for easier reference.

Thanks.

My current house is 8ft7in height until ceiling. The ceiling fan drop around 14in from floor to blade is around 7ft5in. Since I'm tall, if I raise my hand it will be around 7ft7in tall and can touch the blade easily. However, when the fan operate I won't raise my hand below it so it is not a problem. FYI, the blade until ceiling must have at least 12in for decent air flow. The design in your PDF is not recommended and I won't do it this way.

Can you raise the plaster ceiling higher?

Thanks for the advise.

Ceiling unable to raise much higher due to downlights to be installed. Already bare minimum.
Housing for downlights already makan 30cm from slab.

Hi,

This is the KDK recommended installation, the link here



Your sketch shows you have
- 10cm ceiling to fan blade clearance (need another 20cm)
- 2.3m floor to fan blade clearance.. (need another 20cm)

You could probably install as your sketch but it might have problems with short circuit air flow and noise.

Is there space for a 16" dia. wall fan? It might be a better option..

Hi Richard,

Thanks for the link. Hmm, I am using the Deka series, I glanced thru the catalogue, certain models require only 20cm for blade from sofit of ceiling. Is it reliable?

Deka Fan

Put baby fan.

Ceiling can drop down to 5" or less. Conventional downlight with horizontal bulbs usually need minimal 4" clearance. Led need much less maybe you can invest in LED.

2.4m is really low, you may have another problem. Is warmer but if you have Ac it cool faster.

I would think that 20cm would be about the minimum clearance for good installation practice. The criteria being the fan blades giving good air circulation around its working area.

Whether this is reliable, running wise i would think it would be as reliable as one with 30cm clearance all other things being equal. Meaning physically installed properly with gi wall plugs, safety wire connected and electrically wired correctly.

I've not heard of Deka Fans being more familiar with Panasonic/National/KDK but doesn't mean its bad. The catalogue shows a large range so they would have a local service centre for repairs.

Just make sure your fan comes with a Sirim quality and JBE safety sticker and fill in the warranty card.

Seriously I'd still recommend you consider a wall mounted fan. Properly positioned it should give you that cooling breeze and you can have a nice clear European style ceiling. Hang a chandelier with crystal shard lighting would be an idea..

You can put those conceal light (L-shaped type). My new house also very low ceiling around 8ft9in and I just put normal light without plaster ceiling. I prefer high ceiling. L shape using too many unit of light and not cost effective for me.

I bought a few DEKA fans but still haven't installed it. But if 20cm clearance I suggest u buy the panasonic uragi series. I think it is around 20cm but the blade design make it high air flow. If you want DEKA, go for R8 series for high air flow.

I have the same problem.
So I bought Panasonic ceiling fan for the whole house which has the shortest stem. According to Panasonic website this is designed for low ceilings and still provide enough air flow.
It looks like this and the stem is about 12"


Works fine as with my hands up stretched I can just touch the round centre but not the blades.
The other alternative is to modify your plaster ceiling to have a recessed centre part to maximize the floor to ceiling height. You can probably save a few inches (led will require 4") to close to 1 foot ( standard down lights ) by doing this.

I would strongly advise you not to take the risk of installing a ceiling fan which you can touch with hands stretched out. You never know what might happen when we are absent minded or with kids jumping around.

I check with the specs which is why I went for the baby GM series. The one with LED lights. Base on the specification the stem is around 20cm to blades. Hence if currently my ceiling plaster is about 2.5m after installing the clearance to blade is about 2.3m and to base about 2.2m. Should be safe I reckon. Outstretch height is about 2.2m same as doorframe.

Shucks, I should have done more research... 12' is really short. You reckon 2.3m height clearance to blade is ok?

Hi Richard, thanks for the suggestions. Actually I am more concern about the safety. Perhaps you are right a wall mount is better option. But then again due to furniture layout might be a bit hard to position it properly.
Generally my ceiling height is 2.7m and above except for third floor which is why I am having some headache. Haha.

My ceiling to floor is 254 cm or 100".
I'm 5' 9".
As I said I can just touch the bottom centre of the fan.
At 2.3m it is 24 cm or 9.5" lower than mine.
So unless you are 9.5" shorter than me ie about 5' height ( which I am sure you are not ) than I think the clearance is definitely a problem.
I guess you will have a problem installing ceiling fan with your ceiling height.
Consider Dyson stand fan then.
Sorry I can't help much here.

Get a standing fan.or if you can still redo the ceiling make the center sunken and this will allow you to put a fan.

Last week I met a Taiwan manufacturer for box type ceiling fan for the office ceiling. Mainly for low ceiling, but so far only used in offices where it is fitted to sit on the aluminum frames of the ceiling board. Not sure if can use on plaster ceiling, but they are exploring as this is big market. Current design is not very presentable for homes. If manage to get more details, will post here.

Meantime, will advise you not to fit ceiling fan for our low ceiling. Maybe baby fans would be safer.

Is it a must for you to put plaster ceiling? The thing I mentioned previous about the concealed light design (L shape side plastering or what ever it called) can be an alternative too.

This might be suitable? Apparently for lower ceilings.

You're having the same issue as i faced during renovation. Could not do a full plaster ceiling in the living room as it would make ceiling fan installation impossible.

What we ended up doing was using Light box (or some ppl call L-box) to create a square depression area in the plaster ceiling design. For the area where the L-box is being used, original ceiling height was maintained and fan is mounted directly to the concrete slab above.

End result is as below (this was taken during the renovation before the fan was installed). Am using a Panasonic Nami Jr fan and the air flow is good enough for me.

Yup, I have gotten this for the low ceiling areas.
Apparently after installation I probably have clearance of 2.2m from the base of the fan.
Height probably no issue to clear, even if raise hands probably just touching the fan base but not sure if will feel comfortable under it...haha.

Actually not really but due to some cross RC beams cutting thru directly at the center, it will be difficult to install the fan strategically as well. Even if I do a L shape box, you will see 4 separate small recess boxes. That's why it is a real headache.

if you see the attachment you will understand. That's why I having a headache...

I think you fully aircon easier la.

Go for Panasonic FM14E2, meant for low ceiling.( RM 375 )
BTW, i have done some research, most of the fan stem from ceiling to blade is 425mm ( 17"). I actually measured quite numbers of fan belongs to friends and family as well as my current home.

Hhhhhmmm.... was going to say go for strips lighting as in the pic below but it wouldn't really work because your fan will need the space. How does your ceiling line up to your living area?

Like in the pic i posted earlier, the ceiling doesn't really align with the living area either due to ceiling beams as well. Had to improvise a little. The finished ceiling is aligned from the front all the way to the kitchen but it doesn't align with the main door and neither does the ceiling fan sit directly over the living area either.

Not totally ideal but had to work within the limitations. End result was ok lar... living area can still feel the air from the fan but not as strong as if it was directly overhead.

Hope that helps spark an idea maybe.

does anyone know where i can buy a Ceiling fan with a 5 foot rod (it's high ceiling).

What would be a reliable brand for a high ceiling fan?

Thanks,
EK
