Breathing Gas

Fill services and breathing gas.

Hyper-pure, accurate gas fills are at the very heart of our business. The key to clean, accurate fills is the proper tools, and we have a Bauer high-volume compressor, Haskell gas boosters, and the Tri-Hunter 6000 Trimix Mixing Stick and the largest bank of air and Nitrox in Northern Virginia. If you need breathing gas - we have you covered.

All the breathing gases we offer are all oxygen-compatible.  We are currently banking pre-made Enriched Air/Nitrox which allows you to safely purchase our Enriched Air/Nitrox in your non-oxygen clean cylinders without expensive cleaning fees and time consuming cylinder service.
