2 fans are intake, 2 are output, so it would be more accurate to find a setup that moves 500cfm per miner with 0 static pressure, and 0cfm at 58 mmH2O. Or 500cfm per miner and 28 mmh20 if you are doing two duct fans, on one the intake, one on the output.

Also, you'll need an even higher static pressure spec depending on how long your ducts are.

Need to research this more I guess. I was going to add 1x1200 cfm duct fan and split it to 2 machines on the intake side, and another 1200 cfm duct fan on the exhaust side for every 2 machines. ducts were 8" and about 8ft long. Input side was going to have a filter box capable of 1300 cfm

Duct fans were the AC Infinity 10" duct fans with a reducer to 8" ducts
