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 the next step in low pressure applications, tested at 150 psi and 1,500 ppm for 99.4% rejection.

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.
