New grow room exhaust?

Hello I was wondering if someone could give me some visual ideas on setting up an exhaust system for a new lung room.

There is ONLY 1 exhaust line , there will be a in-line fan in each tent. Need help for a 6” duct fitting to accommodate ALL 3 tents???
Thanx for any links or input.

Just use 2 of these first and second tent in one then the duct from that to the next tent and connect the duct from tent 3 to the next y and out the window or where ever you are venting to outside your lung room :slightly_smiling_face:

Are you doing any kind of expulsion to outside or is it contained, recycled air?

…and if you need flow one-way only.
