The SpectraPure MaxCap 180 GPD RO/DI System incorporate high-flow high-rejection TFC membranes, a MicroTec 1 micron Sediment Pre-Filter, a High-capacity Carbon Block Pre-Filter, and two DI (Deionization) Cartridges. The first DI cartridge is the MaxCap DI with 3.5x capacity of other mixed-beds and the second cartridge is the custom formulated 10 SilicaBuster Color-Change DI cartridge.Features:Ultra-high purity water at an economical price; water purification systems maximizing pure water production through application of the laboratory grade deionization resins used in our specialty deionization cartridges Two high-silicate removal Reverse Osmosis 90 GPD MembranesHigh-efficiency MicroTec 1 micron Sediment Pre-FilterHigh-capacity Carbon Block Pre-Filter (9,000 gallon chlorine removal)MaxCap DISilicaBuster color-change DI cartridgeClear filter housingsFilter wrench and garden hose adapterDimensions: 20" x 7" x 16"3/4 garden hose adapterUser Manual (pdf format in new window)Replacement Filters (you might want to order replacements at the same time you order your RO):-MicroTec 1 micron Sediment Pre-Filter: SF-MT-1-10 or SF-MT-0.5-10-Carbon Block Pre-Filter: CF-1-10 or CF-0.5 -10-SilicaBuster Color-Change Deionization (DI) Cartridge: DI-SB-CI-10-MaxCap DI Cartridge: DI-MC-10-Two RO Membranes: MEM-90SpectraPure RO Systems remove over 98% of sediment, chlorine, pollutants, bacteria and other contaminants, to produce high-purity, good tasting water. SpectraPure Systems operate on normal city or well water with pressure greater than 40 psi, and are designed for home, hobby, and light commercial applications.SpectraPure RO Systems will:remove over 98% of all ionic impuritiesremove over 95% of organic impuritiesremove colloidal and particulate impurities remove microorganisms and pyrogensremove chlorine, chloramines, pesticides etc. SpectraPure Reverse Osmosis Systems provide superior rejection of ionic, organic and particulate impurities and thus produce contaminant-free water.
