DOT certified. PCP Tank Explanation

Where can I have a scuba or HPA air tank filled?

Check locally for dive shops or paintball fields. You can also contact a regional cylinder tester for businesses that will be able to fill your tank. Whether it is a dive shop, paintball field or some other business providing the service, confirm they can fill to 4500 PSI. In our experience, tank fills range from $5 to $15.

Do I need an adaptor?

Some fill stations may require fill solution FAH007. Please contact your air fill provider for their specific needs.
