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.


We have two high capacity compressors which means less downtime due to maintenance and breakdowns, and faster gas fills. All of our air is double filtered, oxygen compatible air so you can be certain our air is of the highest standard. We have installed a scavenger pump into our blending system which allows us to do high percentage nitrox mixes and trimix even if we are low on oxygen or helium.

Although we do all our mixes in house, in order to get the most accurate mix possible we ask our customers to leave their cylinders for mixes with us at least overnight. Where this isn’t possible we will need the cylinder for as long as possible.

For all mixed gas, customers must provide a valid certification card for the gas they have requested. NO CARD – NO GAS!
