All Filters offers a wide range of high-quality products, including options for brackish water membranes, seawater desalination, and energy-saving systems. The cross-reference chart helps you quickly find the right industrial RO membranes by providing a direct comparison between brands and models. The chart lists SpiroPure membrane types alongside popular brand names like Toray, Axeon, LG Chen, and their equivalent models. Getting your water treatment systems from All Filters offers the following benefits:
Ultra low-pressure, or ultra low energy elements, require two-thirds the pressure for standard operation as traditional membranes while still providing top performance. We also offer extremely low-pressure elements for lower energy consumption. The energy-saving membranes feature a wider 34 mm feed spacer that improves energy efficiency. Furthermore, we offer fouling-resistant industrial RO membranes with a wider feed spacer and high surface hydrophilicity, making them ideal for high-capacity, low-fouling applications.
All Filters is your all-in-one solution for high-performance water treatment systems at affordable prices. Our friendly and knowledgeable team is available seven days a week to provide assistance with any inquiries regarding your filter purchases. Whether you’re ordering seawater desalination, fouling-resistant, or brackish water membranes, we make the online shopping experience quick, easy, and convenient. Order now and receive high-performance filtration membranes.
