Specs: Model: M-T1812A50 Total Length: 11.75 In. Membrane Length: 10.0 In. Diameter: 1.8 In. Flow Rate: 50GPD / 190 LPD Material: TFC (Thin Film Composite) Stabilized Salt Rejection: 98% Certified to NSF/ANSI 58 for the reduction of Arsenic, Barium, Cadmium, Chromium (Hexavalent), Chromium (Trivalent), Copper, Turbidity, Fluoride, Lead, Radium 226/228, Selenium, and TDS. Applications: In-Home drinking, cooking, plant, and pet water. Office, lab, restaurant, bar, coffee café, or any other point of use application that requires pure, clean water. Universal Standard Size: AMI membrane elements are designed to exceed 50 GPD flow rate. Actual flow rate depends upon water pressure and condition. Performance specifications based on 500 ppm tap water, 50 psi (0.35 MPa) applied pressure, 77°F (25°C) feed water temperature, feed water pH 7-8 and 15% recovery. Element permeate flow may vary ± 15%.. Suitable for most reverse osmosis/deionization (RO / DI) systems such as iSpring, APEC, LiquaGen, APEC, Aquatic Life, Express Water, Axeon, Global Water, Microline, COSTWAY, Dow Filmtec, GE, Watts Premier and all other standard under-sink RO systems.
