REGEN RESIN RECHARGE, 1.1 CUFT is a deionized resin that works together with standard wire EDM water filters to elimitate or decrease dissolved as well as solid contaminants. It is made domestically via a batch process that separates the anion from the cation beads. This recycled resin is cleaned, rinsed, remixed and ready to use—providing a more economical option over virgin resin.
