Pentair 20" Big Dual Gradient Density Cartridge 25 Micron -1 Micron (20" x 4½")

Pentair® Pentek® DGD Series Cartridges are manufactured from 100% pure polypropylene.

DGD Series Cartridges are designed for purity and will not impart taste, odour or colour to the liquid being filtered. Additionally, the polypropylene construction provides superior chemical resistance and is not prone to bacterial attack.

Pentek  DGD Series Filters' advanced design combines selective final filtration with appropriate pre-filtration to achieve up to three times the dirt holding capacity of similar size sediment cartridges and even greater capacity than standard spun or string-wound cartridges. The larger diameter of the filter reduces the particle load, allowing it to operate at higher velocities. The effective filter depth is increased to a full 233%. This increased depth provides very high particulate reduction efficiency and added loading capacity.
