Product Overview

The SpiroPure SP-XL4040 Extremely Low-Pressure Industrial Reverse Osmosis Membrane Element 4 x 40 is a high quality extra-low energy replacement membrane filter cartridge. The SP-XL4040 low pressure RO membrane performs RO filtration at 1/2 the operating pressure of a traditional industrial RO membrane, allowing for lower energy consumption and operating costs for low salt and TDS applications. Choose the SpiroPure SP-XL4040 low-pressure 4040 industrial RO membrane as a compatible replacement for the DuPont FilmTec XLE-4040 commercial RO membrane and other compatible models listed below.

FAQs on 4040 Industrial RO Membrane

What is a SpiroPure SP-XL4040 RO membrane?

The SpiroPure SP-XL4040 is an Extremely Low-Pressure ELP 4040 industrial reverse osmosis membrane element measuring 4" x 40". It performs RO filtration at roughly half the operating pressure of a traditional industrial RO membrane, reducing energy consumption for low-salt and low-TDS applications.

What is the use of a SpiroPure SP-XL4040 low pressure RO membrane?

The SP-XL4040 is used in industrial and commercial systems treating low-salinity water sources where reducing energy costs matters, such as production of purified water, boiler feed water, and food or beverage processing applications requiring consistent, energy-efficient output.

What is the flow rate of the SpiroPure SP-XL4040 membrane?

The SpiroPure SP-XL4040 produces an average permeate output of 2,400 GPD (±15%) at 100 PSI, tested against 500 ppm feedwater NaCl. Its low operating pressure requirement helps keep energy costs down relative to standard industrial membranes. The SP-UL4040 is also rated at 2,400 GPD, but at 150 psi with 1,500 ppm NaCl test feedwater. Because the test conditions differ, compare each model’s specifications with your feedwater and system requirements before choosing a replacement.

Is the SP-XL4040 suitable for low TDS water?

Yes. The SP-XL4040 is specifically designed for low salt and TDS applications, with a maximum recommended NaCl of 2,000 ppm. For higher-salinity brackish sources, a standard or brackish water rated membrane like the SP-BW4040 is a better fit.

Which models are compatible with the SpiroPure SP-XL4040?

The SpiroPure SP-XL4040 is manufactured as a compatible replacement for the Dupont Dow Filmtec XLE-4040 extra low energy membrane as well as Hydranautics Nitto ESPA4-4040, Hydronix Hydron HLE-4040, LG Chem LG BW 4040 UES, and Toray TMH10A, matching their 4" x 40" extremely low-pressure specifications.

How much does the SpiroPure SP-XL4040 cost?

The SpiroPure SP-XL4040 is priced well below comparable OEM extremely low-pressure elements for equivalent 2,400 GPD performance. See current pricing on this page, since compatible replacements typically cost a fraction of brand-name equivalents.
