The American Airworks BoomBox™ 5500 PSI Dual SCBA/SCUBA Containment Fill Station is a 5500 PSI Class 2 dual-position containment fill station designed for the safe and efficient refilling of SCBA and SCUBA cylinders. Third-party explosion tested and compliant with NFPA 1900:2024 standards, this station is ideal for fire departments, public safety agencies, and SCUBA operations requiring dependable high-pressure cylinder filling.

Equipped with an integrated air cascade control panel, the BoomBox™ provides precise refill control while maximizing the number of cylinder refills compared to traditional bulk fill systems. Features such as gas-assisted door operation, tilt-out cylinder trays, dual fill hoses, and a single-action locking bar make cylinder loading, unloading, and filling safer and easier for operators.
