In Line Bath Extractor

[Jupiter01]

I've had this and it packed up after 4 years:

Airflow Aventa 4"/100mm In-Line Duct Extractor Fan up to 187 m3/hr | Aidelle_Airflow (4000001)

The extractor pushes moisture out via an upright vent pipe which goes out of the roof. The run is around 3.5m. I have set this with an over-run of 15 mins and it's managed to push the moisture through.

Now that I am replacing this, I wanted to check if there is a better - perhaps more powerful and energy efficient - option. I would welcome your suggestions.

Maybe this one

100mm Mixed Flow In-Line Fan c/w Timer | Manrose (MF100T / UMD100TX)

That’s ideal. Will place an order for this.
I assume “c/w” means that it includes the time function? Not come across this and there’s no mention of the timer.

Also, it suggests that fkexible ducts provide best extraction rate. I always thought that rigid duct was preferable.

I’d appreciate your guidance on this.
