4" x 40" Extra-Low Energy Reverse Osmosis Membrane | Tap or Brackish Water | 2,860 GPD at 100psi

AMI Extra-Low Energy (Low Pressure) XLE RO Membrane elements are specially designed to run at 100 psi while producing similar product flow as standard elements at higher pressures. By using these elements in your commercial reverse osmosis system, you can significantly reduce your operating costs in tapwater and brackish water applications.

AMI XLE Extra-Low Energy RO membrane elements produce high quality water from tap or brackish water in small commercial RO systems, and are among the finest in the industry.  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 Low Energy Commercial RO Membranes are constructed of low pressure tap water TFC (thin film composite) membrane material and fit standard PVC and Stainless Steel RO Membrane Housings. 

AMI Membranes are Made in the USA in their ISO 9001:2015 Certified Facility and are 100% Quality and Performance Tested.

AMI Membranes Product Specifications

Note: Performance specifications based on 500 mg/l sodium chloride, 100 psi (0.7 MPa) applied pressure, 77ºF (25ºC) feed water temperature, pH 8 and the recovery listed in the table above. Element permeate flow may vary ± 20%. Caution: Do not run these membranes at a pressure that will produce more than their rated product flow rate. This will lead to premature fouling of the membrane resulting in drop in permeate flow and higher TDS of the permeate.
