considering 78% of the air we breath is nitrogen... i don't think so. IF
anything you want oxygen free air as O2 will decompose rubber. In high
temp situations, i could, i guess, see a reason to run N2 or oxygen free
air. As for inert, N2 is somewhat inert, but not really inert like the
Nobel/Inert gasses.   So all in all, i'd say it is scam. sorry.
