Specifications:

• Dual Grade 25/1micron DGD-2501, 4.5" x 10": 25 micron outside and 1 micron inside: Dual grade filter cartridges will remove 2 to 3 times the amount of sediment that standard spun or string wound filters remove.
• DGD Series cartridges are manufactured from 100% pure polypropylene and are sized for use in Big Blue filter housings or stainless steel 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.
• 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 many more times that of standard spun orstring-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 postfilter, 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 Seriescartridges make them an excellent choice for all residential, rural, municipal and commercial applications.
• Maximum water temperature 145F
