4 Inch Ultra Low Pressure Reverse Osmosis Membranes (4″ Extreme Low Pressure)

They are designed for low salinity water to operate at ultra low pressure (ULP). The high permeability results in up to 40% lower energy consumption compared to standard elements.
These membrane elements are based around 100-110 PSI (around 7 bar) test working pressure, please check each membrane details below
