SDC SERIES - 4.5" x 20" Graded-Density Sediment Depth Filter - SDC-45-2050

  • Manufactured from 100% Pure Polypropylene
  • Graded density for higher dirt holding capacity
  • 50 Micron Nominal Filtration
  • Buy in Bulk: 6 per box


  • These 4.5" x 20" SDC Series Cartridges have true multi-stage depth filtration integrated into their design.
  • Utilizing four (4) separate layers of micron filtration, outside-in flow allows the outer layers to trap larger-sized particles, resulting in much lower pressure drop compared to conventional filters.
  • Trapping various sized particles layer-by-layer, the SDC Series Cartridges provide a much higher dirt holding capacity than standard spun polypropylene and string wound cartridges.
  • Ideal for Point-of-use (POU) and reverse osmosis applications.
  • These cartridges can be used in a wide range of applications such as residential, food service, commercial and industrial.
