Robust-Aire™ systems pump compressed air from a shore-mounted compressor through self-weighted lines to a diffuser on the pond, lake or tank bottom. The diffuser then continuously releases micro-bubbles that rise to the surface carrying large volumes of water. This induces oxygen transfer as well as beneficial water movement and mixing.
