4" x 40" Seawater RO Membrane | Watermaker Replacement Membrane | M-S4040A (Replaces SW30-4040) | 1950 GPD (4" x 40")

AMI Seawater Desalination Reverse Osmosis Membranes produce high quality drinking water from seawater and are designed for use in WaterMakers, Shipboard Applications, and Land-and-Sea Based Desalinators. These elements are made in the USA in our ISO 9001:2015 Certified manufacturing plant. Membrane elements are wrapped in fiberglass to increased pressure and TDS tolerance.100% Quality Check and Integrity TestedFits Standard 4" x 40" Fiberglass Seawater Membrane HousingsHigh Quality RO Membranes with Consistent Performance Applied Membranes is a major supplier of RO membranes which are sold under the AMI brand. Since 1983, Applied Membranes has manufactured hundreds of thousands of RO Membranes; these elements have earned the reputation of consistent quality, reliability and performance.This element can be used as replacements in WaterMaker Seawater Desalinator RO SystemsOperating Conditions:Performance specifications based on 32,000 mg/l sodium chloride, 800 psi (5.5 MPa) applied pressure, 77ºF (25ºC) feed water temperature, pH 8 and 8% Recovery. Element permeate flow may vary ± 20%. Maximum operation pressure: 1000 psi (6.9 MPa) AMI 4040 membrane elements are may be used as direct replacements for most industry-standard 4" x 40" seawater Membrane elements, including: SW30-4040, FT-MB-SW4x40 , and most other Industry-Standard 4x40 Size Seawater RO Elements - for use in any system using these membrane elements. Some common systems using these elements are: Farallon 1800c, Farallon 2800c, LandBased 1800 (LB 1800), LandBased 4000 (LB 4000), FL-1800c-110-12, FL-1800c-110-24, FL-1800c-220-12, FL-1800c-220-24, FL-1800c-24, FL-2800c-220-12, FL-2800c-220-24, LB-1800M, LB 1800 M, LB 1800 F, LB-1800F, LB 4000 M, LB-4000M, LB 4000 F, LB-4000F, and many more.
