Country of Manufacture: United States (USA) AMI Extra-Low Energy (XLE) RO Membrane elements are specially designed to run at 100 psi while producing the same product flow as standard elements, significantly reducing operating costs. With hundreds of thousands of membranes in operation in water filtration systems world-wide, AMI membranes have earned a reputation of delivering consistent, reliable, and long lasting performance, making AMI Membranes the natural choice for use in small commercial RO systems. AMI XLE RO Membranes are constructed of tap water TFC (thin film composite) membrane material and fit standard PVC and Stainless Steel RO Membrane Housings. M-T4040AXLE can be used as direct replacement for many industry-standard 4x40 extra-low energy RO membrane elements, including DOW FilmTec XLE-4040, Axeon HF4-4040, and Toray TMH10A– as well as most other Industry-Standard "stinger style" 4x40 Size RO Elements which are rated at 100psi. AMI Membranes are Made in the USA in their ISO 9001:2015 Certified Facility and are 100% Quality and Performance Tested.
