The Pentair® Everpure® Endurance High-Flow Filtration systems are designed to treat up to 200,000 gallons of water per SEN cartridge change cycle. The systems use a pretreatment Hollow Fiber Ultrafilter (HFUF), 2, 3, or 4 fine filter cartridges, and a 2SR-BW scale inhibiting cartridge.

• Applications: Multiple Equipment and Combination Applications, High-Volume Installations
• High capacity allows the system to keep up with high water demands and allows longer periods between replacing the filter cartridge.
• The unique pretreatment system features a pleated membrane with a large surface area.
• Sanitary cartridge replacement is simple, quick, and clean; internal filter parts are never exposed to handling or contamination.
