2.5" x 40"  Low Energy Brackish Water RO Membrane | Fiberglasssed Shell | 1000 GPD BWRO LE

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. AM LE BWRO elements are wrapped in a hard shell of FRP for added strength and to withstand higher pressure drops.   

AMI low energy brackish water RO membrane elements produce high quality water from tap or brackish water sources in 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 commercial RO systems.  AMI Commercial LE Brackish Water Reverse Osmosis Membranes are constructed of 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.
