▚ ENRICHED AIR ▚
Nitrox / EANx
Breathing gas with more than 21% oxygen — EAN32 and EAN36 are the standard recreational blends. Less nitrogen means longer no-stop times on repetitive mid-depth days, traded against an oxygen depth ceiling (MOD). Requires the cert, an analyzer, and the green-and-yellow band culture of labeling every fill.
