R Series Pleated Polyester Cartridges

  • 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)

R Series 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 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 unitized end cap and gasket. The overlap seam is sonically welded to reduce internal bypass improving filtration efficiency.

The standard 9-3/4" length cartridge has more than four square feet of polyester fabric, while the larger Big Blue version has more than 16 square feet. The media is pleated to maximize dirt-holding capacity and extend the time period between changes or cleaning.

R Series cartridges are resistant to both bacteria and chemical attack making them suitable for a variety of residential, commercial and industrial applications.
