Specifications:

• Big Blue Filter Assembly with Dual Grade 50 to 5 micron 1 inch inlet, 20 gallon per minute (gpm) maximum recommended flow rate.
• The filter housing is made from listed pure polypropylene and will hold one high-flow 4.5 x 20 inch filter cartridge.
• This system comes complete with a wall mounting bracket kit, filter wrench, and one Dual Grade 50/5 micron DGD-5005, 4.5" x 20" filter cartridge.
• The maximum recommended temperature is 100F and the maximum recommended pressure 125 psi.
• This Dual-Grade 50/5 micron cartridge will filter fine particles of 5 micron size and up and is often used as a final stage after pre-filtration or as a post filter to an automatic backwashing filter system.
• Dual grade filter cartridges will remove 2.3 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 our Big Bluefilter housings.
• DGD Series cartridges are designed for purity and will not impart taste,odor or color to the liquid beingfiltered.
• 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 Series cartridges make them an excellent choice for all residential, rural,municipal and commercial applications.
