Detailed Description:Extreme Low-Pressure RO Membrane Element-XLP-4040 :2300GPD Commercial RO MembraneReverse Osmosis membrane elements for commercial drinking water systems are the industry’s most reliable method of water filtration. Advanced membrane technology and automated fabrication allow these elements to deliver consistent performance that equipment suppliers, water treatment dealers, and residential customers can rely on. Our Reverse Osmosis membranes are shipped dry for convenient handling and long shelf-life. Our ISO9001-rated membranes are rated at 60 psi and will purify about 20% more water than competitive elements rated at 60 psi. XLP-4040 standard flow is 2300 GPD @ 100 PSI ,Now if you the reduce pressure to 60 PSI,pressure reduced 40% ,therefore permeate flow will be approximately 1440GPDWe suggest changing your membrane every 2 yearsSpecifications2300 Gallon Per Day Membrane for Commercial Reverse Osmosis systems.Certified to ISO 9001 StandardsRemoves particles down to 1/10,000th of a micron (removing 98% of impurities including organic, inorganic contaminates, chemicals, ETC.).Membrane FeaturesProvides stable, high rejection of contaminates even with high TDS water sources.Advanced membrane technology with innovative thin layer composite membrane design.More consistent performance with less fouling requiring less frequent cleaning and change outs.100% dry-stored membrane maximizing shelf life.General InformationThe first full tank of permeate should be discarded, DO NOT use this initial permeate for drinking water or food preparation as it may contain carbon fines and manufacturing by-products.Keep membrane moist at all times after initial wetting.To prevent biological growth during prolonged system shutdowns, it is recommended that membrane elements be immersed in a preservative solution.The membrane shows some resistance to short-term contact with chlorine (hypochlorite). Continuous exposure, however, may damage the membrane and should be avoided.If operating limits and guidelines given in this bulletin are not strictly followed, the limited warranty will be null and void. XLP-4040 Reverse Osmosis Membranes for many Applications such as: Car Washes Whole House Reverse Osmosis Commercial Reverse Osmosis Agricultural Industrial Commonly referred to as: Extra Low Pressure, Extra Low Energy, Ultra Low Pressure, or Ultra Low Energy 4″ x 40″ Fits nearly all standard 4″ x 40″ Membrane housings stainless steel, PVC, or Fiberglass This is compatible with the following common Brands and part numbers as well as others: Dow Filmtec 4040 – Low pressure lines XLP, XLE Vontron ULP-4040 CSM 4040 Hydranautics Axeon HF4 and HF5 Series This is not a Brackish water membrane. It is designed to work best in water that is under 2500 ppm TDS.
