DGD Series Dual-Gradient Density Cartridges from Pentek® are manufactured from 100% Polypropylene, and are designed for purity and chemical compatibility. The spun fibers form a true gradient density from the outer to inner surfaces. DGD Series cartridges are designed for purity and do not impart taste, odor, or color. The pure polypropylene construction provides superior chemical resistance, and is not prone to microbial attack. The effective filter depth of the DGD series is a full 233% higher than standard spun or string wound filters. The unique design and performance characteristics of the DGD Series cartridge make them an excellent choice for residential, municipal, and industrial applications.
DGD Cartridges are sized to Pentek® Big Blue® and Big Clear Filter with both 10 and 20 Sumps.
