Do your windows provide a large enough opening to let in 3500 CFM. That could be part of why you are only getting 2200.
Depending on your time and resources you could create a partition wall so that your extraction fan is only pulling on miner exhaust. One thing you may want to consider is moving your asic rack a little further back towards the red circle. You may be to close allowing some of the exhaust to catch a current after hitting the wall and circulate within the room.

Heat keeps radiating towards the area marked by the red circles. There's some windows that are out of view marked with pink lines. A good gush of wind always rushes threw there, the window marked with green lines has too many trees in the way for that.
The extractor fan there is rated up to 3500 cfm, but my cheapo meter with "ft/min to cfm googled calculators" only measure around 2200 cfm (dunno if the meter is crap or the fan is working really hard under load, or my math was shit?).
The mining equipment in the room is gobbling up around 7200watts of power, an assortment of gpus and antminers putting out an incredible amount of heat. It would be an inferno if the fan dint exist, however heat still slowly creep its way backwards. Is the fan just not strong enough? Or are things improperly positioned?
