Hi TE friends, can you please recommend me an exhaust fan from Amazon for installing in bathrooms?

I've been considering this covered exhaust from Polycab, it looks great, but concerned if it will suck air as well as something without cover. Does anyone have experience with this kind of exhaust? Or please recommend another one. Many thanks.

In my opinion it will make more noise due to that "cover".
The cover obstructs the flow definitely and most probably will cause extra resistance to be overcome by the fan, creating more noise.
What is the problem with visible blades?

No problem as such, covered simply looks better

The point about pests is a good one
 
Can you guys tell me if Atomberg Effico can be used for longer period of time continuously? Unfortunately in my experience, these exhausts are not meant to be used for longer period of time. Their bushes get damaged when used for longer duty-cycles. Since Atomberg is BLDC, it should be better than normal induction motor based exhaust fans?
 
To ensure the exhaust fan doesn't run continuously, connect it to both a light switch and a timer. The fan should activate when the light switch is turned on, and the timer should then automatically shut it off after a pre-set duration, like 10 or 15 minutes.

These don't have bushes neither does induction ones, so they last long. BLDC is more power efficient due to permanent magnets.
If I really wanted to nitpick then Induction ceiling fans are simple where as BLDC has a PCB with electronics components so technically they can fail due component failures as well.

I have been using Atomberg fan since mid 2017, and no complaints. In summers it is on almost 24/7 and have not seen any issues.
Only real issue I have faced is with the flimsy remote controls which break easily.
If you phone has IR blaster you can control them through that as well.

I've been generally annoyed with how noisy and ineffective bathroom exhaust fans tend to be. At a previous residence, I basically threw the fan out and replaced it with a 140mm noctua fan and a 3d printed bracket.

I think it was the most effective exhaust fan I've used since the place never fogged up with hot showers.

And can you tell me the washroom dimensions? I am thinking of doing the same.
 
It's a bit hard to recall and verify this, but floor plans say it was around 8' by 5'. I didn't really take room size into consideration - my rationale was simply that the the air displacement of even an nf-a14 at full speed would wreck the average traditional exhaust.

I am thinking to mount a NF-A14 on 100mm long pipe (that my washroom already has). It's a vertical pipe of around 5 meter in length. Do you think the air flow will be enough for this?

It's hard to ever be certain, but I'd recommend getting an ippc 3000 rpm fan if you're concerned. They're much more suited for the task imo due to water resistance and higher airflow.

That's a great idea. How to give the fan power supply?
