This "high static pressure" fan was able to create a static delta P of .002 PSI when dead-headed.

The strongest axial fan that EBM Pabst makes produces a maximum back pressure of 310 Pa = 0.044 PSI = 0.00306 Atm. It is not FRC legal (24.7" dia., 52.6 lb, requires 277 Vac @ 8.18 A). At work, we measure the effectiveness of the cooling fans installed in our equipment using an anemometer not a pressure meter.
