Multi room ventilation units

Recommendations please..
To service 4 en-suite bathrooms.
All on 1 level, average run of 5m

Vent axia do a nice multi vent switch operated but then it will vent all the bathrooms it is quiet though. I am not sure about getting it to switch from each bathroom. I suppose a JB with all switches going to it and the final wire going to the switch board on the multi vent???

Thank you
That would be perfect if it had 4 separate outlets that boosted up based on humidity or when lights get switched on.

It does have four outlets, hmm hang on maybe not. If not you can get a double vent to adapt it.

I have fitted quite a few of these commercially and one place some five years ago. No trouble so far they have performed marvelously.

or when lights get switched on.

Have you considered the problem of back feeding other lights when using one fan controlled by 4 Bathroom lights
