As the Title says i need reviews on BLDC Fans. Though i have read many reviews on Amazon, Flipkart etc most are confusing!
I am a bit confused because:
1. It’s a bit expensive as compared to regular fans
2. Since it’s BLDC Local mechanics may not know how to repair it (If it needs repairs after warranty period) so anyone has any experience with repairs by local mechanics?
3. How is the Air Flow/Circulation? Many reviews point that Air Circulation is an issue and sometimes it gets slow automatically.
Any other point i may have missed?

Using it for 2 years, no problem, but points to be noted give direct connection and earth is must, Electrician will say  not needed but

stay close and make sure earthing is done, never use normal regulator, from switch the current must be direct to fan.


Air output is 70% of normal fan

Using Atomberg gorilla fans since 3/4 yr without earthing no issues. Bill is nearly 1/3 less also running fan on lower speed consumes very less electricity.
Haven’t faced any issue with fan speed or air circulation as I don’t need fan running at full speed.
Only issue is fan blades attracts too much of dust and hence regular cleaning is needed, consider it as free air purifier stuck_out_tongue

Nope. I never really looked into fans till date, never knew there were so many variations and power efficient ones sad

That looks like a great statistic. Seems to offer lots os saving in terms of power consumed.

I was planning to replace all the tube lights in our home to LED ones in a phased manner, looks like researching into these gorilla fans has it’s own benefits too.

1. Yes it is a bit expensive but it’ll save your electricity of 35-50% so by 2nd year you ll recover the whole amount paid for the fan.
2. local repair is an issue but the company provides 3year warranty. All company provides service in metro cities so it shouldn’t be an issue.
3. Air Flow/Circulation depends on the shape of the blade. This is nothing to do with the motor.

After a lot of deliberations, i have decided not to buy them.
Firstly, because i dont live in metro city, i am very skeptical of their service in my area. Yes, i have heard their service is very good, but as i said, my city is not very developed as such. Moreover, i contacted our house technician, and he has no knowledge of this technology. This technology is fairly new, and who knows the lives of these fans. I didn’t have to repair our fans even once for maybe past 10 years, and if for once any of my fan at home goes wrong, i cant wait for a month to get it repaired.

Secondly, what this company does is they compare a 28w gorilla fan with 75w ordinary fan with full 1 year usage and touts the annual savings of 1500/year (who uses a fan for 365 days tho?). But the thing is reputed companies like havells have come up with 35-40w fans that are running successfully, and thus the savings look a bit dull then. Moreover if the technology was good, dont you think these companies would have invested themselves in this.

Lastly, they do have some speed issues, and also you will have to give up on some fancy stuff too (if that matters)
Hence, thought against buying them.
And yes i did a lot of research as i had to replace atleast 10 to 15 fans at my place.

I am eventually getting one just because it can run for much longer off the battery in case of longish power cuts.

How is the air delivery compared to a conventional fan? Another user claims it to be 70%. That seems scary… If it doesn’t delivery sufficient air, what use is the savings?

Few things:

  • Local electricians can’t fix them as it involves complex electronics, the motor(spinning one) 99.9% doesn’t spoil, its the electronics that sits behind that gets damaged in some situations. I work in this technology, making the hardware, developing the firmware for the micro-controller inside to spin the motor as per the requirement. It some times gets very tricky to debug the hardware/software. But few designs(chinese) in the market are based on ASIC chip where if they get damaged, the possibility of repair is zero.
  • From what I dealt with customer requirements, they never compromise on the air delivery and the speed at which it has to run. But the air delivery can change based on the fan-rod that you use. If you go against the recommended rod length and reduce the length, the effective air delivery will be reduced. It all depends on what customer specifies when the design is started.

It is like inverter air conditioners or inverter washing machine, where they work as long as they don’t encounter any unwanted conditions, otherwise they are almost similar in terms of the behind-the-screen technology

BLDC fan can run on DC supply ? (Assuming inbuilt SMPS)

I am using gorilla fans from more than 1 year.. I have not encountered any issue till now. The fans seem maintenance-free. My other fans (Bajaj, Luminous) have suffered some issues within 3 years.. Power saving is real deal not just for electricity billing, but also for inverter usage(my area has frequent power cuts). In terms of speed, I have found it to be superior than the 2500 bucks priced luminous fan in the next room. Also, in terms of sound, it feels less irritating compared to conventional fans. Remote control is another bonus. I’d recommend these bldc fans without doubt and would also love more competition and interest from other brands.. (As far as I know, Orient electric aeroslim smart fans also have bldc motor and that fan is pretty expensive)

Brought orient one from flipkart 2 days back. Already installed. Only the remote sensor is a problem which is orient fan flaw not in jupitor or gorilla. Air flow is very good in fact better than normal one imo.
I am very satisfied overall.

The unit takes AC input as a whole, and eventually converts to 24V DC (most likely). This is usually taken care by SMPS unit inside.

Thanks for the detailed review. You have cleared much of my doubts. I will not buy these as of now as i need to buy 7-8 fans so can’t take risk with these. I will take the risk when i need to buy 1-2. Any suggestions on normal fans? Need a bit fancy. Not too overly fancy but not completely white/brown ones too

If you run fans for above 10hr go with BLDC only. In ac room, you should use BLDc fans. Because normal fans ll generate more heat. Going with BLDC is like upgrading from CFL to led. You could mix normal fans with BLDC fans. Use BLDC fans in rooms which you use must.

Based on the above personal user reviews, i think you should go with BLDC fans, at least those which you think would be running the most. Like, 3-4 out of those 10-15 that you need. Since those would recover their money faster. And anyhow, if its going to recover its price in 2 years, which is within warranty period, you should definitely go with few of these. This way, while saving on your bills, you would also get to experience them first hand. Will help decision making for future purchases.
Buy for those rooms which would be running for the longest hours.

Get 2,3 BLDC out of your requirement of 7,8 fans for those rooms which would be running most.
