The DEDEPU S3000 0.5L mini scuba tank is crafted from 6061 aviation-grade aluminum alloy, weighing just one-third of a steel tank.

A 150-micron hard-anodized coating (HV500+ hardness) provides triple protection: resistance to seawater corrosion, impact, and surface abrasion. The built-in balanced regulator delivers a constant 1 MPa airflow, ensuring smooth, steady breathing regardless of the pressure level inside the tank.

It holds dual certifications: DOT-CFFC-68 and CE.Meets EN250:2014 breathing air standard,40 meters deep safe backup.Passed 200+ rapid charging and discharging tests by a third-party organization,meeting the basic performance pf NFPA 1986 emergency breathing system.

Its modular, quick-release design complies with FAA 49 CFR §175.10 standards, and its dimensions ( Φ40×300mm) fit 99% of aircraft overhead bins (IATA tested). With an actual system weight of 1.5 kg (including the valve and regulator), it is suitable for carry-on travel.
