Pentair Pentek PCC212 cartridges contain hexametaphosphate crystals that dissolve slowly into the water to help inhibit scale and rust build-up. Rather than filtering sediment, this cartridge treats water chemically: hardness particles are held in suspension so they cannot precipitate and form deposits when heated, a protective coating is formed on metal surfaces to help inhibit corrosion, and dissolved iron up to 1 ppm is sequestered to help reduce staining and discoloration.
Built with a polypropylene shell, polypropylene post-filter and Buna-N gaskets, the PCC212 handles maximum hardness of 15 gpg and a pH range of 6.5 to 9.0 at temperatures from 40 to 100 degrees F. Maximum dimensions are 9-3/4" x 2-5/8", so it drops into number 10 Standard or Slim Line filter housings.
Effective for up to six months at 1 to 1.5 gpm, the PCC212 is recommended for ice machines, coffee and vending machines, food service equipment, water heaters, air conditioning equipment and other water processing equipment. It is not recommended for main line water applications with flow rates exceeding 3.0 gpm.
