The Oase FiltoClear 15500 delivers powerful mechanical and biological filtration with integrated ultraviolet clarification in a compact, high-capacity system designed for fountains, formal spillways, pond-free features, water gardens, and ponds up to 15,500 gallons. Built with a durable, impact-resistant housing that can be buried up to the clamping ring for discreet installation, the FiltoClear uses four densities of replaceable filter foams (10, 20, 30, and 45 ppi) with improved support plates to maximize filtration efficiency and extend service life. A patented UVC Cleaning Rotor keeps the quartz sleeve clear for optimal UV performance, while Easy-Clean Technology with a two-way valve allows simple backflushing and waste discharge without opening the filter. Integrated monitoring lets users check UVC operation, filtration performance, and pollutant levels while replacing UV lamps without removing the cover, and bypass technology ensures constant water flow to prevent clogging. With 2" inlets and outlets for flexible plumbing, a switchable cleaning handle connected to internal rods for fast foam flushing, and optional winter drain capability, the FiltoClear combines convenience, efficiency, and reliable performance. The system includes four filter foams, two 84W UVC bulbs, metric 2" fittings, and five 2" Sch40 adapters, supports flows up to 5,200 gph, and is backed by a 2-year warranty plus 1-year extension.
