Our Sediment filters use a multi-media bed comprised of a variety of gravel and sand to trap suspended particulate matter, such as clay and silt, which gives water a cloudy appearance. The result is clean, clear water. The sediment filter filter bed facilities more thorough backwashing and prevents channeling. Periodic backwashing with our calendar clock control valves cleans the bed.Electrical 110V/60Hz standard (all valves)Clock initiatedSuperior fiberglass mineral tank with color choice of white, blue, or blackMulti-media Layered Media BedGravel under beddingProduct FeaturesFully adjustable down flow or up flow regeneration cyclesChoose from 3 modes of operation: immediate regeneration, delayed meter regeneration, or delayed time clock regenerationSolid state microprocessor with user friendly front panel, LED status indicators display the time of the day, usable capacity remaining, regeneration, cycle in progressDiagnostics displaysBackwash capacity dandles tanks up to 12 diameter for softener applications, 10 for filter applicationsHigh Impact UV stable, flame retardant polycarbonate protection hood is pressure sealed for added protection against moisture, dust, and dirtStandard 9V alkaline battery backupTimed auxiliary outputThe professional Product Program backs the 6700Up flow or down flow regeneration SpecificationsCF: .75Mineral Tank Size: 8x44BR>Peak (GPM): 5Range (GPM): 1-3 Height: 57Shipping (lbs): 80
