Summary
Product identification
The Pentair® Pentek® DGD Series Cartridges are gradient density filters manufactured from 100% pure polypropylene. They are designed for use in Pentair Pentek Big Blue® Filter Housings.
Key features include:
- Designed for purity; will not impart taste, odor, or color to the filtered liquid.
- Polypropylene construction provides superior chemical resistance and is not prone to bacterial attack.
- Advanced design combines selective final filtration with appropriate pre-filtration.
- Achieves up to three times the dirt holding capacity of similar size sediment cartridges.
- Effective filter depth is increased to 233%.
- Spun fibers form a gradient density from outer to inner surfaces.
- Suitable for residential, rural, municipal, and commercial applications.
- Nominal micron ratings available: 1, 5, 25 micron.
- Available lengths: 10", 20".
- Tested and Certified by NSF International to NSF/ANSI Standard 42 for material requirements only.
Operating limits
- Temperature Rating: 40-145°F (4.4-62.8°C)
