Streamline by eliminating another hose from your system. The Air Link combines the performance and reliability of an octopus and a power inflator into a low-profile, streamlined package. The breathing performance is superior to that of many conventional octopus regulators. The Air Link may be purchased separately, or pre-installed on your AERIS Buoyancy Compensator. Easily add to any AERIS BC in minutes, or purchase installed with a new BC for additional savings.
