Look for DC fan. DC fan mostly are higher range in all their model.

Based on the spec sheet the two smaller sizes' cfm is even less than my windless wonder. The biggest size one cfm is good. However, I would rethink based on the cost as 3k can get you more aircon units than 2 atas fans

Aeratron is from nsb?

I have the fino 2 and b fan... They are well built and function as they should...

How long they last..i have no idea... Mine are 1 years old

I think aeratron got fake one. I read in SG forum, most who complained actually bought the fake ones.

K14XZ or K14YZ is just cosmetic 4 or 5 blade. No yuragi. Standard blade only.
If got budget get the V touch Jr instead, the blade design produce better wind. The place where u want a prettier fan can put Sensa 4.

KDK Kaze compare with KDK Sensa 5. Size is huge 60" so wind very good. But your mounting clearance must be enough to support 150cm (60" fan). Some developer assume you need to put full height cabinet in all rooms and as such the clearance only ngam for 140cm fan, 150cm one will dig a trench into the wall. Kaze should be super atas model. Sensa 5 has everything you need I guess.

KDK Sensa 4 atas model than the V touch Jr (4 blades and 140cm for both). Sensa 4 more gear in the gearbox (9 vs 5 spd) and DC motor. Both got yuragi. Both also function well.

I would analogy them as:
the cheap 3 blade regulator: old 1970 mustang. yes still carburetor and look outdated but wind damn good because of the 60" 150cm
the standard remote 4 blade K14XZ or YZ: Iswara 1.3 (the model before BLM)
the vtouch jr: 2003 camry 2.4 (exceeds normal use expectation just that it has outdated 4AT gearbox, most atas 140cm fan that still have AC motor)
the sensa 4: E 300 BlueTEC Hybrid (pretty and bling bling DC motor)
the kaze or other stuff: 2020 AMG tuned merc GT 63S (modern fast ride with price to match)

IMO, the vtouch jr shud be the minimum benchmark standard. Beyond the sensa is rather overkill.

So, did you buy Aeratron in the end?

Oo. I guess I cannot get review from you since I need to decide on the fan for my living room by next week already

Finally bought mine. Didn't check properly when I collect from the shop yesterday. Today when installed only noticed there is a crack in one of the blades. A huge one.

Called NSB to ask if they sell replacement blade for the fan. They ask me to send the photo of the cracked blade. But since I reported almost end of their working hours, I have to wait for them to respond tomorrow. Finger cross they admit this is a manufacturing defect and replace them for free. Otherwise I guess I have to fork out money to buy replacement blade (if any ).

On the other hand, all my alpha alkova dezi works perfectly. Very good air movement despite at low speed.

Actually it was pretty much my mistake not to check them properly even when the shop opened the box in front of me. I only check if the components were complete and not the physical state of the fan itself. So, there is no way I can prove that it was crack out of the box.

I bought an FR 43” as well. The fan was fine. Wind was strong even at slow speed. But... yesterday I noticed that there is a kruk kruk sound coming out from the fan. My contractor already told me about that but it wasn’t noticeable unless when in complete silence. Will report to them tomorrow.

I guess their QC is pretty shit, hopefully the aftersales is decent.

I bought my AE3+ 60” at full price RM1699. The FR 43” was RM10 cheaper from full price
