R Series Sediment Water Filters | Pleated Sediment Water Reverse Osmosis Filters

R Series Reverse Osmosis cartridges are manufactured from a durable, non-woven and reusable polyester fabric that is suitable for a wide range of filtration uses.  The media is pleated around a polypropylene core for added strength and the ends are are immersed in a thermo-setting vinyl plastisol. Embedding and sealing each end of the pleat in this fashion fuses the three components together forming a unified end cap and gasket. The overlap seam is sonically welded to reduce internal bypass improving filtration efficiency. Features Pleated design maximizes dirt-holding capacity Versatile and reusable, allowing for a variety of uses Durable polyester media is bacteria- and chemical-resistant Nominal 30-micron rating (R30) and nominal 50-micron rating (R50) NSF Certifications The R50-BB is Tested and Certified by NSF International to NSF/ANSI Standard 42 for material requirements only.
