AMFOR®  reverse osmosis (RO) elements offer the highest quality water for small commercial systems.

 

*AMFOR membranes are available in a variety of sizes to meet a wide range of space requirements. Nowdays, AMFOR TW30XLE-3020-600, TW30XLE-3020-1000 have been widely used in commercial drinking machine.

 

*AMFOR XLE extra low energy elements operate at the lowest pressure in the industry,resulting in lower energy costs and enabling system builders to use lower cost components.

 

*In addition to the highest quality water and the lowest energy costs, AMFOR membranes also deliver savings by  providing the industry's longest lasting and most reliable performance.

1. Permeate flow and salt rejection based on the following test conditions: TW30 elements are tested on a 2,000ppm NaCl- feed stream, XLE performance based on a 500 ppm NaCl feed stream, pressure specified above, 77F  (25℃) and the fol owing recovery rates; TW30-3020 , TW30-2521, XLE-2521, TW30-4021, XLE-4021 - 8%, TW30-2514, TW30-4014-5%, Other-15%

2. Permeate flows for individual elements may vary +/-20%.
3. For the purpose of improvement, specifications may be updated periodically.
