DGD Pentek Series Dual-Gradient density cartridges
DGD Series cartridges are manufactured from 100% pure polypropylene and are sized for use in Big Blue filter
housings. DGD Series cartridges are designed for purity and will not impart taste, odor or color to the liquid being filtered.
Additionally, the polypropylene construction provides superior chemical resistance and is not prone to bacterial
attack.
Features
• Manufactured from pure 100% polypropylene
• Designed for purity and chemical compatibility
• Spun fibers form a true gradient density from outer to inner surfaces
The DGD Series’ 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. This performance enhancement is achieved by combining two separate gradient layers in one
filter. The larger diameter of the pre-filter reduces the particle load to the post filter, allowing it to operate at higher velocities.
The effective filter depth is increased to a full 233% of standard spun-polypropylene or string-wound filters.
This increased depth provides for very high particulate reduction efficiencies and added loading capacity. The unique design and
performance characteristics of the DGD Series cartridges make them an excellent choice for all residential, rural, municipal and
commercial applications.
