More air, same compact size—this portable backup system delivers extended emergency breathing when it counts.

The Spare Air 600 expands on the original concept by delivering 6 cubic feet of breathing gas—double the capacity of the Spare Air 300—while maintaining a compact, easy-to-carry form factor. It shares the same length but features a slightly larger 3.25-inch diameter.

Designed as a redundant gas supply for safety-conscious divers, it can be used for self-rescue or shared with another diver in an emergency. The unit is compatible with both air and nitrox gas mixes, offering flexibility across different diving setups.

Travel-friendly by design, the Spare Air 600 can be safely transported by draining the tank and removing the on-demand regulator. Once at your destination, the included adapter allows for easy refilling from a standard scuba tank.

A hook-and-loop holster is included for secure attachment and quick deployment when needed.
