Dupont AmberLite HPR4700-CL Form Anion Resin, 1.0 Cu. Ft. (28.3L)

Dupont Marathon A anion exchange resin is specifically designed to give high throughput and economical operation in primary demineralizer beds. Because of its uniform particle size, this resin offers a number of economic advantages over conventional resins. The small uniform bead size of DowEx Marathon A resin results in rapid exchange kinetics during operation, more complete regeneration of the resin, and faster, more thorough rinse following regeneration. It can be used for all types of water but especially recommended for waters that have a high percentage of silica and carbon dioxide.
