Water Pro 4040 ULP Reverse Osmosis Membrane

The Water Pro 4040 ULP membrane is ideal for commercial and industrial reverse osmosis systems requiring ultra low pressure operation.
Built from TFC (Thin Film Composite) material, it ensures excellent salt rejection with significantly reduced energy consumption.
Compatible with standard 4040 vessels, it fits a wide range of applications such as city water, low-TDS wells, agriculture, and car washes.
Standard size (4" x 40") allows easy integration into existing RO systems.
