Pentek - DGD Series 10" x 4.5" Big Blue Dual-Gradient Density Polypropylene Sediment Filter
DGD Series 10" x 4.5" Dual-Gradient Density Polypropylene Filter
The Pentek DGD Series combines two gradient-density layers in a single cartridge to handle heavy sediment loads without sacrificing flow rate. The outer pre-filter layer removes larger particles while the inner post-filter layer captures finer sediment, extending service life and maintaining consistent pressure across residential, municipal, and commercial applications.
Available Models and Performance Data
| Model Number | Micron Rating | Dimensions | Pressure Drop | Max Flow Rate |
|---|---|---|---|---|
| DGD-2501 | 1 micron | 10" x 4.5" | 1 PSI @ 10 GPM | 10 GPM |
| DGD-5005 | 5 micron | 10" x 4.5" | 1 PSI @ 10 GPM | 10 GPM |
| DGD-7525 | 25 micron | 10" x 4.5" | 1 PSI @ 10 GPM | 10 GPM |
Why Dual-Gradient Design Outperforms Standard Cartridges
The DGD Series uses two distinct polypropylene layers with different pore structures. The larger-diameter outer layer functions as a depth pre-filter, capturing bulk sediment and preventing premature loading of the inner core. This staged approach increases effective filter depth to 233% of standard spun or string-wound cartridges, allowing the inner post-filter to operate at higher velocities without fouling. The result is exceptional particulate reduction efficiency and dirt-holding capacity that extends replacement intervals in high-sediment well water, municipal supply pre-filtration, and commercial process applications. The 100% polypropylene construction resists chemical attack and bacterial growth while maintaining zero taste, odor, or color contribution to filtered water.
Housing and Application Requirements
All DGD Series cartridges are sized specifically for Pentek Big Blue 10-inch housings with 4.5-inch diameters. These filters are ideal for whole-house systems, well water applications requiring high sediment removal, commercial pre-filtration stages, and municipal supply polishing. Select micron ratings based on source water quality: 25-micron models for heavy sediment loads and pre-filtration, 5-micron for general whole-house use, and 1-micron for final polishing or sensitive equipment protection. Compatible with standard Big Blue housings including Pentek #20 and #10 series.
