The knowledge and practical skills to blend nitrox mixes safely and correctly — understanding partial pressure blending, oxygen compatibility, and the standards that keep high-percentage oxygen work safe. One day that changes how you think about your gas.
Most technical divers have no idea what's actually in their cylinder beyond the analysis sticker. The TDI Gas Blender course changes that — covering partial pressure blending, continuous flow blending, equipment handling, and the oxygen compatibility and cleanliness standards that make high-percentage oxygen work safe. High-oxygen environments are not forgiving of shortcuts, and this course is built around understanding why, not just following a procedure.
It's a one-day course with a strong practical focus. By the end you'll have actually blended gas on real equipment — not just covered the theory in a classroom. Malta has full blending facilities available, and the hands-on experience makes the theory significantly more useful.
If you're heading into technical diving — Advanced Nitrox, Decompression Procedures, and beyond — understanding how your gas is made is genuinely useful knowledge. It makes you a better diver and a better team member.
Pairs really well with Advanced Nitrox — doing both gives you a thorough understanding of not just how to use high-O2 mixes but how to make them. A lot of serious technical divers do both.
Gas Blender gives you a qualification to blend nitrox mixes independently. More practically, it gives you the knowledge to understand what's in your cylinders and have an informed conversation with whoever's filling them. If you want to go further with gas blending — helium mixes, trimix — the Advanced Gas Blender course builds directly on this one.
