4" x 14"  Low Energy Reverse Osmosis Membrane | Tap or Brackish Water | 610 GPD at 150 PSI

AMI Low Energy (Low Pressure) RO Membrane elements are specially designed to run at 150 psi while producing the same product flow as standard elements. By using these elements in your commercial reverse osmosis system, you can significantly reduce your operating costs in tap water applications.

AMI 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 2,000 mg/l sodium chloride, 150 psi (1 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.
