Yep, the blower I use supplies just over 4in H2O of air-pressure at full speed, which is rather extreme. Your typical 100CFM 12cm fan will provide in the vicinity of 0.30in H2O of pressure.

The air-pushing potential of the blowers is like chalk and cheese when compared to axial fans when pushing through restrictions. Axial fans are great for low-restriction/open air moving ability, but slow greatly in their tracks when presented with restrictions.

I guess one could compare it to low-head high-flow water pumps (axial fans), to closed-impellor high-pressure low-flow water pumps (like the Iwaki Z-series pumps or the Swiftech MCP600), just like BlackEagle did above.
