Jandy's large cartridge filters set the benchmark in cartridge filtration. They are technologically advanced and filled with many user-friendly features. The large cartridge filter design takes advantage of the filter's total surface area, providing the clearest possible water and extended cleaning cycles. The new CV filter is designed to work more efficiently with other Jandy products by incorporating the Versa Plumb system. This filter is equipped for high flow rates and optimum hydraulic performance. The CV large cartridge filters are constructed of durable, corrosion-resistant, heavy duty high-tech polymeric materials for long-lasting performance. These filters are available in 340, 460 and 580 square foot models.
