About This

• Optimal Purity & Performance: Achieve exceptional water quality with our XLE-4040 4" x 40" RO Membrane, designed for small commercial systems with efficient performance at very low applied pressures. Capable of producing up to 2600 gallons per day, it features a 99.0% impurity rejection rate, 600 psi maximum pressure, optimum operating pressure of 100 psi (80–150), salt removal rate of 99.00%, pH tolerance of 3–10 with feed water TDS <1000 ppm, and maximum free chlorine tolerance of <0.1 ppm.
• To effectively filter contaminants like heavy metals (fluoride, lead, chromium), organic materials, and harmful minerals, use an advanced 0.0001 micron TFC membrane layer. Each membrane model is designed for different water qualities, so understanding your water chemistry, pressure, and ppm is crucial for selection. Keep in mind that this membrane is not suitable for direct whole-house filtration; a different setup is needed for that purpose.
• Versatile & High Capacity: The XLE-4040 4 x 40 inch RO Membrane is designed for whole-house, agricultural, and industrial applications. This membrane delivers a robust capacity of 2,600 GPD and allows for seamless integration with industry-leading models, including Dow Filmtec XLE-4040 and HF4-4040.
• Durable & Long-Lasting: Shipped dry in a sealed package to maintain peak condition, the XLE-4040 Membrane is built for longevity, with a life expectancy of 24 to 36 months depending on water quality, temperature, and pressure. Constructed with BPA-free components, it ensures that no toxic plastic materials are used, making it safe for all water filtration needs.
• Best-in-Class Membrane Quality – Engineered with 90 ft² (8.36 m²) active membrane area to deliver maximum output, durability, and long-lasting filtration performance.
