Removes as much as 90–95% monovalent ions, 95–99% polyvalent ions and greater than 99% particles, microorganisms and dissolved organics from potable tap water. Ideal as pretreatment for Nanopure* Infinity systems or for less demanding laboratory applications. Unique Membrane Protection System (MPS uses state-of-the-art thin film composite-membrane technology and pretreatment to inhibit scale buildup on membrane surface for superior water quality and extended membrane life. Provides up to 15 or 30L/hr. of RO purified water. Minimum inlet pressure is 30psi (2kg/cm2; maximum inlet pressure is 100psi (7kg/cm2. Microprocessor control allows for 24-hour fully automatic operation. Integral pump for consistent flowrates. Automatic flush cleanses RO membranes for ten minutes every four hours, eliminating contaminant buildup. Large pivoting LCD display for monitoring water quality displays membrane % rejection, water conductivity, resistivity, and total dissolved solids (TDS level. Series of internal pressure gauges monitor membrane operating pressure and prefilter performance. Wall- or bench-mounted. Includes one each membrane, prefilter cartridge, carbon pretreatment cartridge and MPS cartridge. System automatically alerts operator when pretreatment and MPS cartridges need replacing. 120V, 50/60Hz. Dimensions: 171/2L x 20W x 225/8 in.H (45 x 51 x 57cm. Shipping weight: 85 lb.
