SpiroPure's NSF-certified 8040 industrial reverse osmosis (RO) membranes, available in the 8x40 size, are designed to fit commercial RO systems and other heavy-duty applications. All Filters’ brackish water 8040 elements provide low-energy, low-pressure treatment of tap water, groundwater, and more. For applications that require even lower pressure, check out our ultra-low pressure elements, which operate at roughly two-thirds the pressure of standard industrial RO membranes.

SpiroPure extremely low-pressure membranes operate at half the pressure of traditional RO elements, reducing energy consumption and increasing savings. If you’re looking for high rejection, our 8040 RO seawater desalination membranes provide high sodium rejection, making them ideal for treating seawater and other high-salinity sources.
Fouling-resistant membranes offer low fouling with a wider spacer and high hydrophilicity, making them highly effective for wastewater treatment. Our energy-saving membrane is another option with a wide spacer that provides high performance with low pressure and energy requirements for more energy savings.
All Filters offers a large selection of products to ensure you can find the right 8x40 RO membrane for your system. Our cross-reference chart helps you choose the best 8040 RO membrane by comparing specifications with top brands. Simply follow these steps:
If you have questions about compatibility or specifications, simply contact All Filters customer support so we can help you find the right product. Our knowledgeable and friendly staff are available to assist seven days a week.
