The RK300PE-HF Protein Fractionator Skimmer is a high-performance filtration device designed for advanced saltwater aquarium systems. Utilizing a sophisticated fractionation process, it efficiently removes dissolved organic compounds and particulate matter from the water column. Air, often supplemented with ozone, is precisely injected into the reaction chamber to create a dense foam, which then collects and exports unsightly and harmful waste. Key features of this fractionator include durable molded HDPE reaction chambers and a highly effective counter-current design. It incorporates tuned Mazzei venturi pumps with Kynar injectors, an ozone gas connection port, and air flow meters for precise control. The unit boasts a wash-down system, an optional automated venturi cleaning system, a secure screw top lid, and a clear sight gauge for easy monitoring. Premium components such as MDM pumps and Spears piping and fittings, both made in the U.S.A., ensure robust and reliable operation. This advanced protein fractionator is ideally suited for large-scale reef aquariums, public aquariums, or demanding commercial aquaculture operations that require exceptional water clarity and purity. Its robust construction, high-efficiency design, and comprehensive feature set, including the ability to connect ozone and automated cleaning options, make it an indispensable tool for maintaining pristine water parameters and supporting sensitive marine life over the long term.
