1 fan extract from two tents?

any one use 1 fan to extract two tents? obviously would need a bigger fan, a "y" adapter but i see damper units advertised:

quote"For controlling air flow

If you are going to use a Y-Piece to duct from more than one area then it is essential that you use a Damper Unit to maintain an even airflow between the two areas. Air will always follow the path of least resistance, so if you're ducting from two different sized areas or if one length of ducting is longer than the other, you will not get even extraction from each area. By using a Damper Unit you can even out the flow of air by creating resistance in one of your ducts.

Top Tips: to even up airflow between two equally sized grow rooms, the Damper Unit should be placed at the end of the shorter length of ducting. When extracting from rooms of differing sizes, place the Damper Unit in the smaller room. "

I know someone who extracts from 3 1mx1mx2m tents with an RVK200L1 using 3x125mm carbon filters with no issues. He was just very careful with his duct lengths. As he was using a 1-in & 3-out system, instead of a Y-piece he made a wooden box & used 3x125mm & 1x200mm spigots to connect the ducting up.

Could you not just run them in series? I know it is not the same but i have 2 rooms; one has 1 fan for input and 1 for output but the output blows into the the second room which has it's own exhaust fan. Room 2 is regularly 2degrees higher than room 1. Both work really well with most heat issue tamed.
