Gas Fills
At Amphibian we offer air, nitrox, 100% oxygen and trimix fills. All gas fills are done in house by our specially trained team.
At Amphibian, our gas station is built for reliability and quality. With two high‑capacity compressors, we minimise downtime from maintenance or breakdowns and provide faster, more efficient fills. All of our air is double‑filtered and oxygen‑compatible, ensuring every cylinder is filled with the highest‑quality breathing gas.
We’ve also installed a scavenger pump within our blending system, allowing us to produce high‑percentage nitrox mixes and trimix even when oxygen or helium supplies are running low.
To guarantee the most accurate blend possible, we ask customers to leave cylinders with us overnight for mixed‑gas fills. If that isn’t possible, we’ll need the cylinder for as long as you can spare it so we can achieve the best result.
For all mixed‑gas fills, divers must present a valid certification card for the gas requested. No card – no gas.
