You cut off that quote:

So the tubes are low pressure. Perhaps not vacuum, but in reality so called vacuum tube delivery systems aren't actually a vacuum either, that's why a more accurate name for them is Pneumatic Tube Systems.

I'm not sure what it is exactly you're trying to argue, above you made it sound like the system isn't low pressure at all.
