Compact 2.5 x 21 Seawater RO Membrane for Small Boat Watermakers

  Compact 2.5 x 21 Inch Seawater RO Membrane for Small Boats Introduction The 2.5 x 21 Inch Seawater RO Membrane is a vital component for small boat watermaker systems, engineered to produce fresh water through efficient seawater desalination. Designed for DIY enthusiasts and small boat owners, this high-performance seawater reverse osmosis (SWRO) membrane boasts a 99.6% salt rejection rate, ideal for marine applications. When paired with the Pumptec 107SS pump (sold separately), it delivers approximately 24-30 gallons per day (GPD), perfect for boats with limited power. For optimized setups, it can produce up to 200 GPD with a pump meeting the manufacturer’s recommended flow rate. Compatible with the 2.5 x 21 inch 1200 PSI fiberglass pressure vessel (sold separately), and proudly made in the USA, this membrane ensures top-quality performance. Adding a second membrane can  increase output even with the Pumptec 107ss, enhancing efficiency and decreasing the runtime of the system. Key Fe
