Summary
Product identification
Pentair® Pentek® R Series Cartridges are manufactured from a durable, non-woven, and reusable polyester fabric suitable for a wide range of filtration uses.
Key features:
- Pleated design maximizes dirt holding capacity
- Versatile and reusable
- Durable polyester media is bacteria- and chemical-resistant
- R30: Nominal 30 micron rating
- R50: Nominal 50 micron rating
- Available in lengths: 4.88", 10", 20"
Operating limits
- Temperature Rating: 40-125°F (4.4-51.7°C)
Mechanical / hydraulic
The media is pleated around a polypropylene core for added strength. Standard pleated endcaps are immersed in a thermo-setting vinyl plastisol. Big Blue® cartridges have a molded endcap with gaskets. The pleated ends are sealed to the endcap with a thermoplastic adhesive. The overlap seam is sonically welded to reduce internal bypass, improving filtration efficiency.
- Filter Media: Non-woven polyester
- Standard Endcaps: Vinyl plastisol
- Big Blue® Endcaps: Polypropylene
- Core: Polypropylene
The standard 9.75" length cartridge has more than four square feet of polyester fabric, while the larger Big Blue® version has more than 16 square feet.
