Description

The XLP11-4040 Reverse Osmosis Membrane is a high-performance extra-low pressure 4-inch thin-film composite (TFC) membrane designed to produce high-quality purified water while operating at very low pressures. Its advanced membrane technology delivers excellent salt rejection and high permeate flow, helping to reduce energy consumption and overall operating costs without compromising water quality.

Designed for commercial and light industrial reverse osmosis systems, the XLP11-4040 is ideal for treating municipal water, borehole water, and other low-salinity feed water sources. It is widely used in bottled water production, food and beverage processing, laboratories, commercial water purification systems, and other applications requiring reliable, high-quality purified water.
