Frequently Asked Questions (FAQs)

1. What do Divers have in their tanks?

Standard scuba tanks come with compressed air, for ease of calculations we say air contains 79% nitrogen and 21% oxygen. The actual breakdown of air is closer to 78.09% nitrogen, 20.95% oxygen and 0.96% covering all the other gases in our atmosphere, such as Argon, Neon Helium, Methane and Krypton.

2. Can you fill your own dive tanks?

you can fill your own bottles if you wish - but not with a "std" garage compressor. you need several thousand psi (at a minimum), no garage compressor is going to do that. personal scuba compressors are available starting at ~ $2000, they have the filters ( and yes you can purchase aftermarket filters too) included.

3. Does scuba tank air go stale?

Do not store tanks that are full of air for prolonged periods of time (no more than 3 months. A tank should be stored with just enough pressure (200 psi) to keep moisture out. Remember the higher the tank pressure, the greater the corrosion that may form inside.

4. Can you refill diving tank rust?

The amount of oxygen left is indicated on the icon of the Diving Tank. It has a maximum of 600 seconds worth of oxygen. Similarly to the Jackhammer, once all the "durability" of the Diving Tank is gone, it can be refilled at a workbench.
