Applied Membranes 4" x 40" Reverse Osmosis Membrane | Tap or Brackish Water | 2,900 GPD at 150 psi Low Energy RO Membrane (Low Pressure Membrane) AMI Part Number: M-B4040ALE Membrane Size (Nominal): 4 x 40 Membrane Dimensions: 4"Dia. x 40"L Flow Rate: 2,900 GPD (10,976 LPD) Applied Pressure: 150 psi (1 MPa) Stabilized Salt Rejection: 99% Outer Wrap: Fiberglass Wrapped Membrane Type: Tap or Brackish Water Feed Water Test Temperature: 77°F (25°C) Single Element Recovery: 15% Chlorine Tolerance: 0 Feed water pH Range: 2-11 End Style: Male PWT (Stinger Style) Country of Manufacture: United States (USA) AMI Low Energy (Low Pressure) LE RO Membrane elements are specially designed to run at 150 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 LE Low Energy RO membrane elements produce high quality water from tap or brackish water in small commercial RO systems. 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 RO Membranes are constructed of TFC (thin film composite) membrane material and fit standard PVC, Stainless Steel, and Fiberglass RO Membrane Housings. M-B4040ALE can be used as direct replacement for many industry-standard 4x40 RO Elements with 3/4" male product water tubes ("stinger style") rated at 150psi – including BW30LE-4040, LC LE-4040, LE-4040, LP-4040, AK4040FM, AK4040TM, TMG10, HF1-4040, HF6-4040, RE4040-FL. AMI Membranes are Made in the USA in their ISO 9001:2015 Certified Facility and are 100% Quality and Performance Tested.
