SpiroPure 8040 RO Membranes: Quality and Performance Filter You Can Trust

Q: What is the price of the 8040 RO membrane?

SpiroPure 8040 RO membrane pricing varies by membrane type. Brackish water, ultra-low pressure, fouling-resistant, and seawater desalination models are each priced differently. All Filters offers 8040 membranes at significant savings compared to branded OEM. Check individual product listings for current pricing and availability.

Q: What are the specifications of the 8040 RO membrane?

The SpiroPure 8040 membrane measures 8 inches in diameter by 40 inches in length, the largest standard ro membrane industrial size. Permeate flow reaches up to approximately 10,500 GPD depending on membrane type, water quality, and operation. Salt rejection rates range up to 99.7%. See the cross-reference chart on this page for full model-by-model specifications.

Q: Is the 8040 RO membrane durable and long-lasting?

Yes, with proper system management. SpiroPure 8040 membranes are NSF-certified and built for sustained heavy-duty operation. Expected service life is typically two to five years. As with all RO membranes, lifespan depends on consistent pretreatment, operating within rated pressure limits, and protecting the membrane from chlorine and fouling.

Q: How do I install the 8040 RO membrane?

Lubricate the brine seals and O-rings with clean water or food-grade silicone before insertion. Slide the element into the pressure vessel with the flow arrow matching the direction of water filtration. Secure end caps and connections per your vessel manufacturer's specs. For multi-element arrays, confirm feed-to-reject flow direction before pressurizing the system.

Q: Is the 8040 RO membrane compatible with all types of water filters?

SpiroPure 8040 membranes are compatible with standard 8040 pressure vessels from most major manufacturers. Use the cross-reference chart to confirm your OEM or similar part number maps to a SpiroPure equivalent. Membrane types typically match to source water conditions and operation as originally designated by the system or installer.

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.
