Cool tube + filter connection

[dubite]

Greetings there icmag'ers
Will get my hands on a 125 mm cooltube these days which I will connect with my 2 (in out) 125 mm vents. However, I have trouble seeing how to connect the Can 125mm carbon filter, since it can be connected only on one side. (the other side is has no connecter) What can I do in this situation?
Hope this makes sense and that you can enlighten me with a solution since I am here scratching my head..

Cool tube + filter connection

Filters only open on one end so air/odor gets pulled through side of canister...removing the odor...blowing filtered air through cooltube & pushed out of the growroom (usually)

easy!!!!instead of cleaning your smelly air and exhausting where ever you do have your filter running threw your cool tubes and then exhaust where ever you usally do

That would mean no more intake fan and the setup would look like this:

carbon filter - fan - cooltube - exhaust fan?

That could work fine.
Variables that come into play include room size, temperature, fan type/power, light wattage.
Probably more too but I'm still learning + the forgetful sort

any second opinions?

My system is connected: Carbon-Exhaust fan-airpipe-Cooltube-Airpipe->Out of the growspace
I'm not sure I'm getting what your problem is

Absolutely incoherent -- congratulations.

Just do what everyone else has said, put the carbon filter at the very beginning of your exhaust line. that way all the hot smelly pot air will flow into the filter before it leaves the grow space. Trust me, you dont want to have to build an enclosure for the filter just to make it connect the other way. The filters are made to have air only flow in one direction -- pulled, not pushed.

That would mean no intake anymore and using both fans for exhaust innit?
My problem with this setup was that I couldn't see how one would also use and intake but apparently that is no longer required.

you can have as much intake as you want, let as much fresh air in as you need that is fine.....the key is negative pressure inside your grow space. by pulling the air from the growspace thru the carbon filter, then thru your cool tube then out you should be exhausting clean air......

You can still use an active intake (fan) but it doesn't need to connect directly to the cool tube/filter setup. To do so would not allow fresh air to the plants. But also, you can ditch the second fan and just use the one. As long as you are pulling from one end of the exhaust, the hole you provided for the intake will have air coming in to your space because of the negative pressure. And negative pressure is how you control where the smell and heat goes.

Adding an intake fan of equal size as your exhaust fan would be canceling out the negative pressure pull effect. If anything, since the exhaust is being weighed down by the resistance of the carbon filter, you may end up with a slight positive pressure, meaning smell might leak out before being scrubbed by the filter.

Again, passive intake would be just fine. The fan to bring air in as you suggest would not really be necessary, or you may want to hook up the second fan to your exhaust if the cfm's for the one isn't enough, IOW if it doesn't get close enough to ambient temps.

Hope that is clear enough.
