FWIW, the second i looked at that fan i laughed, and was praying this was a joke, doing HVAC, we have to size fans, calculate duct sizes, velocity, drag coefficient etc, NOTHING at the level of what greg is doing, but that fan MIGHT be large enough to be a booster fan in a small duct run, capable of 2 inches of water gauge, or roughly .07psi HAHA
