Inline fans in series or parallel?

[Toke+Choke]

ive basically got my extracted air from the tent going up a 6m soil pipe and above everyone's houses on the street I've got 2x250M3/h in line fans and I want as much pushing power as possible to send the extraction all the way up the pipe.
Now my question is series or parallel setup? And what sort of cfm power are we talking with those two combined?
Thanks dudes.

Series circuit

Parallel circuit

Link the fans series, and you may get a fall in grunt ..?

also should one fail, the other will fail as well

go parallel, for this reason, so yeah if one fails..?

for whatever reason the other is still running

parallel, as in wiring them up to the same circuit

but with their own leads

good luck

I don't mean within wiring aspect dude.
I mean within the ducting with the actual fans them selves I.e.

Filter>fan>ducting>fan>outside
OR
Filter>fan
>ducting to outside
Filter>fan

If that makes any sense at all.

Ever tried to clean that thc oily shit off of a fan...?

have the filter inside the tent,

also less acceptable to atmospheric humidity

go

Filter>fan>ducting to outside

A parallel series is the best of both worlds.

I still don't think either of you guys are grasping what I'm saying.
I've got 2 fans right and I want to use them both for extraction do I put them both inline with one big filter on the inside of the tent obviously
OR
2 individual smaller filters in the tent with one inline fan on each going to a Y connector so both air from those are coming out of one hole?
Are we on the same page yet lol?

Run parallel with 2 filters. Be sure to increase the exhaust duct size where the 2 fan exhaust merge to meet the volume needs of both fans.
Each fan will get it's full cfm rating minus the drag of the carbon filter. Where with 2 fans inline the cfm will not get much over the rating of the lowest rated fan, but it will create a greater drag force (negative pressure) which will pull more cfm through the carbon filter than the single fan does but does not exceed the combined cfm of the 2 separate fans.

So I think I'm going with one big filter and 2 fans in line with each other.
My fans are 4" 250m3/h
So I'm looking at a carbon filter around 425m3/h would this scrub smells effectively?

Or maybe even a 350m3/h filter.
