What is Nitrox? Enriched Air | Manta Diving Lanzarote

What is Nitrox?

What is Nitrox?? When we normally dive, we dive on air, a gas mixture of 21% oxygen, 78% nitrogen and 1% other gases. Nitrox or enriched air is when we dive on a gas mixture of greater than 21% oxygen.

In recreational diving we dive on mixes up to 40% oxygen. Here at Manta Diving Lanzarote our most common blend is 30% oxygen. We’ve found it is the best balance between extending our no stop limit and not limiting our depth.⁠

Why do we use it?? To extend our no stop limits and dive for longer! By reducing the % of nitrogen in the mix, we reduce the risk of bubbles forming in the bloodstream and extend our no stop time. For diving in Lanzarote if you are diving to 30 metres nitrox is a game changer, especially on your repetitive dives. If you were to do your first dive to the Blue Hole and then after your surface interval you wanted to dive to the Cathedral it would be possible. However you wouldn’t get long inside the cavern. Change that gas mixture in your cylinder for nitrox and you get plenty of time to poke around in those nooks and crannies! ⁠

Take a look at the following air/nitrox comparison table. Showing you that the higher oxygen % you breathe the longer your no stop time.

Nitrox is becoming more popular all the time, it’s also becoming more readily available. We have our own Nitrox membrane and have 25 cylinders dedicated to Nitrox, that we fill onsite. However it is not something to be taken lightly. It requires special training to be used properly and safely. So before you dive with enriched air, be sure to get the necessary training and gain the appropriate certification. Here at Manta Diving Lanzarote we offer nitrox training with the PADI Enriched Air Speciality
