Do I need a diving certification in order to get a sport diving gas fill?
Yes. To receive an Air fill, we require a SCUBA diving certification.
To receive a fill with any Nitrox mixture of 40% or less Oxygen content, we require a Nitrox Diver certification.

Filling a cylinder is not just to connect it to the compressor and wham, it's full.

There are cylinder fill rates to consider.

There is the overheating problem.

You want 3,000 psi, and my compressor can deliver.

What type of certification must I have to get a technical diving gas fill?

To receive a fill with any hyperoxic mixture greater than 40% Oxygen content (including pure Oxygen), we require a Technical Diver or equivalent certification.

To receive a fill with Helium mixtures, a Trimix Diver or equivalent certification is required.

We will observe any specific mixture restrictions that appear on your C-card.

We interpret Normoxic Trimix to mean a Helium mixture with an Oxygen content between 18% and 24%.
