Filmtec (XLE-4021) Low Energy Membrane 1025 GPD 4" X 21"
Filmtec XLE-4021 Low Energy Membrane
The Filmtec XLE-4021 is engineered for commercial systems requiring up to 1025 gallons per day at the lowest operating pressure in the industry. With 36 square feet of active membrane area and 99.0% stabilized salt rejection, this 4" x 21" element reduces energy costs while delivering consistent purification performance for tap water feeds.
Engineered for Efficiency and Reliability
Extra Low Energy Operation
Operates at lower pressure than standard membranes, reducing energy consumption and allowing use of lower-cost system components without sacrificing output.
1025 GPD Capacity
Rated at 1025 gallons per day (3.9 m³/d) under test conditions of 500 ppm NaCl, 100 psig, 77°F, and 8% recovery for small commercial applications.
99.0% Salt Rejection
Stabilized salt rejection of 99.0% removes dissolved solids, contaminants, and impurities to produce high-quality purified water consistently.
Compact 4" x 21" Design
Standard commercial format with 36 square feet (3.3 m²) of active membrane area fits a wide range of housings and system configurations.
Proven Filmtec Technology
Backed by Dow's industry-leading membrane technology, delivering the longest lasting and most reliable performance in commercial RO applications.
Lower Total Cost of Ownership
Reduced energy requirements, extended membrane life, and compatibility with lower-cost components translate to measurable operational savings.
Commercial Tap Water Systems
The Filmtec XLE-4021 membrane is designed for small commercial reverse osmosis systems purifying less than one gallon per minute from municipal tap water sources. Ideal for cafes, restaurants, laboratories, small manufacturing operations, and offices requiring reliable purified water. Compatible with standard 4-inch commercial housings. Individual element permeate flow rates may vary +/-20% from nominal specifications.
Filmtec membranes are manufactured by Dow and represent decades of membrane research and commercial deployment worldwide.
