      Somebody has to actually make the nitrox. This course teaches you how.

      Every enriched air fill you've ever taken for granted came from somewhere. A qualified person, following specific procedures, blended that exact oxygen percentage, cleaned the equipment it touched to the right standard, and made sure what ended up in your cylinder was safe to breathe. The PADI Gas Blender course is where that knowledge actually lives.

      This isn't a diving course. There are no dives involved at all, it's a technical, classroom-and-workshop certification covering the physical properties of oxygen, the hazards and handling requirements involved, and the practical methods used to blend accurate nitrox mixes. All course materials and equipment for the duration of the workshop are included, so there's nothing extra to source beforehand.

      It's a genuinely useful certification whether you're aiming to work at a dive operation, want to properly understand the fills you rely on every time you dive enriched air, or you're simply the kind of diver who wants to understand the mechanics behind the sport rather than just the diving itself.

      Where Gas Blender Takes You

      Once certified, you'll understand the full process behind producing accurate, safe nitrox fills, oxygen cleaning procedures, gas properties and hazards, and the recognised methods used to blend enriched air to within the correct tolerance of a target mix.

      This certification is a genuine asset at any dive operation that offers nitrox fills, and it's a natural next step for divers considering work in the industry or already spending time around gear, fills, and dive centre operations. It also sits alongside Enriched Air Diver as a natural technical progression, since one teaches you to use nitrox and the other teaches you how it's actually made.

      Ready to understand what's really behind every nitrox fill? Book your Gas Blender course below, or get in touch with our team if you've got questions about how this fits your diving or career plans.

      What This Course Entails

      The course is built around independent study using the PADI Gas Blending manual, followed by instructor-led practical workshops, no open water dives are involved at any point.

      You'll cover the physical properties of oxygen and the different forms and purities it comes in, the hazards and special handling requirements involved in working with it, and what oxygen cleaning of equipment actually requires. Practically, you'll work through the recognised methods for blending an accurate enriched air nitrox mix, and how to verify that a finished blend is correct before it's ever used.

      Most divers complete the full course, independent study and practical workshops combined, within a single day.

      Prerequisites

      • Hold a PADI Enriched Air Diver certification, or qualifying equivalent from another training organisation.
      • Minimum age is 18 years old.

      Frequently Asked Questions

      Does the Gas Blender course involve any dives?

      No. Gas Blender is a classroom and workshop-based certification with no open water dives involved. It focuses entirely on the theory and practical procedures behind producing safe, accurate gas blends.

      Do I need Enriched Air Diver before the Gas Blender course?

      Yes. A PADI Enriched Air Diver certification, or a qualifying equivalent, is a hard prerequisite, since the course builds directly on that foundation.

      Is this course useful if I just want to understand nitrox better, not work in the industry?

      Absolutely. Plenty of divers take this course purely out of interest, to genuinely understand what's happening behind every enriched air fill they use, without any intention of blending gas professionally.

      How long does the Gas Blender course take to complete?

      Most divers complete the full course, independent study plus practical workshops, within a single day.

      Can this course lead to more advanced gas blending qualifications?

      Yes. Divers interested in technical diving gases can extend their training to cover trimix gas blending as a further step beyond standard nitrox blending.
