Featuring a durable stainless steel build and a spiral-wound, tape-wrapped element, it delivers up to 98% reduction in total dissolved solids, ensuring premium water purity. Its industry-standard 11-3/4" size fits most residential RO units, offering a reliable two-year lifespan under optimal conditions. ## Description Product description RO Buddie & Classic Models This membrane fits standard residential reverse osmosis units, including the RO Buddie and Aquatic Life Classic 100 GPD RO/DI unit. Use two of the 100 GPD Membranes in the Aquatic Life 200 GPD Hydroponics RO unit. Industry Standard Membrane Sizes The 50 GPD Membrane is an industry standard 1812-50 size and the 100 GPD Membrane is a 2012-100 size. Both sizes are rated for ideal pressure of 65 PSI and water temperature at 77°F. Up to 98% TDS Reduction With up to 98% reduction in the supply water TDS, these membranes provide quality filtered water. In applications where zero TDS is desired, you will use less DI mixed-bed resin because the membrane will be removing more of the TDS. Operating Temperature The membranes will work with water temperatures between 50 and 100 °F. Supply water below 77°F will produce less filtered water while temperatures above 77°F will produce more filtered water. Operating Pressure The membranes will work with water pressure between 40 and 100 PSI. Supply water pressure below 65 PSI will produce less filtered water. Supply water pressure above 65 PSI will produce more filtered water. Total Dissolved Solids Reduction The RO membrane reduces impurities known as total dissolved solids (TDS) from the water down to 1/10,000 of a micron.
