2 Extractor fans one ducting - is this ok?

[shabbaranks]

Hi guys,

Looking to install 2 extractor fans within my bathroom and en-suite. Would it be ok to run both through the same ducting? They are the Xpelair C4TSR's so they have the built in back draft shutters. I was thinking if I give them about a 2m-3m run before joining at the main outlet from the building this will give them a bit of a buffer also to potentially stop any form of backdraft or working against each other.

Does this sound ok?

Cheers!

One powerful extractor fan feeding both would’ve been more appropriate.

Problem is we would be controlling the extractors from the light switch so you would have complications. Plus as its the en-suite next to our bedroom and the bathroom we wouldnt want it turning on (even if it is quiet) if someone uses the bathroom so separate systems works better for us.
