Filter & Filter housings

DGD Series – Dual Gradient

DGD Series are manufactured from 100% pure polypropylene and are sized for use in Pentair Pentek Big Blue Filter Housings. Their 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. The larger diameter of the filter reduces the particle load, allowing it to operate at higher velocities.
