AP series

Summary

Product identification

The AP Series consists of Extreme Low Pressure Brackish Water Reverse Osmosis (RO) elements, utilizing an A-series thin-film membrane (TFM*). These elements are designed for high flux and relatively high sodium chloride rejection, ideal for applications requiring high flow and ultra-low operating pressures such as beverage, light commercial, residential, and general industrial uses.
