Beyond just the Navy and the Coast Guard, members of all the U.S. Armed Services rely on safe breathing air for a wide range of applications.

In 1970 Congress passed 30CFR, PartII, SubpartJ, 11.121(b) which states, "Compressed gaseous breathing air shall meet the applicable minimum grade requirements for Type I gaseous air set forth in the Compressed Gas Association (CGA) 'Commodity Specification for Air G-7.1' (Grade D or higher quality)" , making periodic testing of compressed breathing air a law.

Grade D, E, and L, along with internal standards such as the NAVSEA's 'U.S. Military Diver's Breathing Air Standard', have all been adopted for use, depending upon the requirements of each application.

Rocket Air Labs is able to test your unit's breathing air for compliance with all of those standards. We recommend using our Rocket-Air test kit. We are proud to be a part of helping to keep our country's service men and women safe. With several members of our staff being prior service, we understand your needs.
