The A-Series, family of proprietary thin-film reverse osmosis membrane elements are characterized by high flux and high sodium chloride rejection. AG Standard Brackish Water Elements are selected when high rejection and operating pressures as low as 200 psig (1,379 kPa) are desired. These elements allow moderate energy savings, and are considered a standard in the industry.

The AG 2PASS Series has been specifically designed for 2-pass systems. These elements are made of pre-rinsed components avoiding any scaling potential on the second pass at start-up thus avoiding any loss of production.
