The RK2 Systems RK150PE-HF Protein Fractionator Skimmer is a highly efficient filtration device designed to remove dissolved organic waste from saltwater aquariums. Utilizing a sophisticated foam fractionation process, it injects air, and optionally ozone, into a counter-current water flow within its reaction chamber. This mass mixing effect facilitates the formation of concentrated foam, which traps and exports pollutants, ensuring pristine water quality for demanding reef environments. Key features of this robust system include molded HDPE reaction chambers and a wash-down system to maintain optimal performance. It is equipped with tuned Mazzei Venturi pumps and Kynar Mazzei Venturi injectors for efficient air and ozone delivery, alongside an ozone gas connection port and air flow meters for precise control. Other notable components are a secure screw top lid, a clear sight gauge, Hayward or Asahi ball valves, and the highest quality MDM pumps and Spears piping, all proudly made in the U.S.A. This protein fractionator is ideally suited for large-scale reef aquariums, public aquariums, or advanced hobbyists requiring exceptional water purification and industrial-grade reliability. Its design, featuring an optional automated venturi cleaning system and continuous foam ejection, minimizes maintenance while maximizing the removal of organic compounds. For those seeking a top-tier solution to maintain the healthiest possible aquatic environment, the RK2 Systems RK150PE-HF delivers unparalleled performance and durability.
