What is Enriched Air Nitrox?

Enriched Air Nitrox (EANx) is any nitrogen/oxygen gas blend that has been enriched with more than 21% oxygen. This is different from atmospheric air, because it has an approximate percentage of 79% nitrogen and 21% oxygen.

With an added percentage of oxygen, EANx brings about many benefits that divers find more convenient and comfortable to dive with compared to using normal atmospheric air tanks.

Benefits of Enriched Air Nitrox:

  • During Diving

Using EANx would help greatly in extending bottom times. The higher the oxygen content in EANx, the less nitrogen divers breathe in. Oxygen in the body is usually metabolized or absorbed, so divers using EANx end up with lower levels of nitrogen after each dive. With lower levels of nitrogen loaded up into one’s body, it helps divers to stay underwater longer, or to increase the safety margins of diving. Here’s a chart of no decompression limits for EANx compared to using atmospheric air.

Also, using EANx would result in shorter surface intervals. When a diver finishes a dive using EANx, he/she finishes with lesser dissolved nitrogen levels in the body compared to diving with atmospheric air. This is especially helpful when one makes 2 or more dives, because one will have lesser residual nitrogen, leading to a shorter surface interval and a longer time well spent underwater!

 

  • After Diving

It is rather apparent to many divers that diving with EANx would lead to lower levels of post-dive exhaustion. With higher percentages of oxygen to enrich your blood and lower percentages of nitrogen loaded onto your body, there would be a small but beneficial effect on the body.

 

What will you learn?

  • Managing oxygen exposure
  • Practice analyzing oxygen content
  • Using Enriched Air Nitrox with you dive computer
  • Knowledge you need to know before using Enriched Air Nitrox

 

 

Destinations that offer EANx for diving:

There are many dive locations that Enriched Air is preferred by divers. Some of these destinations are:

 

Malapascua, Philippines

Monad Shoal, where thresher sharks and manta rays are spotted, is a great place to use EANx. Since the average depth is around 22m, Divers can get to spend extend their bottom time from 37 to 70 minutes just by switching from air to EANx 36%! This would give you more time to spot these elusive sea creatures! The Dona Marilyn and Tapilon wrecks are also great sites for EANx.

 

Cayman Islands

Orange Canyon, a dive site with an average depth of 19m, is decorated with an array of colourful elephant ear sponges. Diving with EANx would definitely be one of the best ways to admire the beauty of what nature has to offer us!

 

Sri Lanka

Unawatuna, galle is one of the best dive sites to use Nitrox, due to its shallow waters and its rich marine life!
