Hi,
I am new here so hi,
Not sure if I am posting in the right place so apologies if not.
I am converting a camper van (and I smoke)

I need help to see if my plan can work.

General plan.
1x 3” bilge blower.
1x exit hole
3x intakes into the blower - shower, cooker hood, above bed
A way of choosing which intake it’s sucking from (this is where I don’t know if it exist or what terminology to use)
Ideally a way of selecting internal exit or external exit. Ie when it’s -20 outside it can vent inside through carbon filter.

Could this work?
Does anyone know of how I could do this?

Many thanks

A few years.
Blown air pipes have a butterfly valve at the outlet. Could you not fit similar on the inlet?

A word of warning, I fitted a bilge blower to extract heat from around our oven on our van and the bilge blower is unbelievably noisy. :oops2:
Thankfully, we only have it running when we have the oven on in hot weather.

Hi,
Thanks for all your reply’s.
I have already filled my roof with opening roof lights.
I could remove my 40cm one and fit a maxxfan but it’s expensive.
I always planned on having a bathroom and cooler hood extractor but hadn’t given it much thought until now.
I would like to minimise extra holes as they are extra leak points.
Thanks for letting me know the bilge blowers are noisy that will certainly change my plans as I am noise intolerant (or just intolerant).
I am thinking of trying to 3d print a manifold box with a movable flap to choose inlet. Probably deal with above bed ventilation separately.
What are blown air pipes? That sounds closest to my original idea.
Many thanks
