1000 GPD at 100 PSI 4 x 21 inch 99% Rejection Extra Low Energy Membranes

4" x 21" Extra Low Pressure RO Membrane (1,000 GPD, 99.00% Rejection)

This industrial-grade, extra low pressure (XLP) reverse osmosis membrane is engineered for high-performance commercial water treatment applications. Proudly manufactured in the United States by Hydrocomponents & Technologies Inc. (HCTI), this element is designed to fit standard 4-inch by 21-inch pressure vessels and utilizes advanced thin-film composite technology to provide superior filtration efficiency. Operating effectively at a reduced feed pressure of just 100 PSI, this membrane minimizes the energy consumption of high-pressure booster pumps while maximizing system throughput — delivering a highly cost-effective solution for reducing overall facility operating expenses.

This American-made element is built for consistency and durability, delivering a nominal permeate flow rate of 1,000 GPD with a stabilized salt rejection rate of 99.00%, providing robust removal of total dissolved solids (TDS) and other common contaminants for reliable water quality in commercial RO setups. Whether used in small-scale commercial purification or as part of a multi-stage industrial system, this membrane is designed to maintain consistent output even under variable feed water conditions, offering a dependable balance of high flux and stringent, energy-efficient purification.
