150m roll of weighted air hose designed for use with DeepWater Aeration Systems, providing a reliable connection between the shore-mounted compressor and submerged diffusers. With an 8mm internal diameter and 18mm external diameter, the hose is robust, self-sinking, and UV resistant, making it suitable for long-term use in outdoor environments. It can be used to extend or connect diffuser lines, with up to 100m of weighted airline supported per diffuser. For additional reach, a further 30m of underground airline can be added, allowing a total run of up to 130m per diffuser where required.
