Filter Cartridges are product of 100 percent pure polypropylene and are sized to be utilized in Big Blue, Big White and Big Clear Filter Housings. Filter Cartridges are designed for purity and will not impart taste, scent or colour to the liquid being filtered. Additionally, the polypropylene constitution presents stepped forward chemical resistance and isn't susceptible to bacterial attack. It progressed design combines selective last filtration with correct pre-filtration to attain as much as thrice the grime keeping capacity of comparable size sediment cartridges or even larger capability than common spun or string-wound cartridges. The bigger diameter of the filter out reduces the particle load, allowing it to operate at elevated velocities. The effective clear out intensity is elevated to a complete 233%. This elevated intensity gives very excessive particulate discount efficiencies and added loading capacity. The design and performance traits of the Cartridges lead them to a great choice for all residential, rural, municipal and advertisement functions Manufactured from natural 100% polypropylene - Designed for purity and chemical compatibility - Spun fibers kind a gradient density from outer 25 micron to inside 1 micron (DGD-2501) and from 50 micron to 5 micron (DGD05005) - Three occasions the dirt-holding capacity of comparable sized sediment cartridge - NSF certificatedSpecificationMaximum Dimension: 4-1/2"×10”DGD-2501 Rating (Nominal): Pre-filter 25, Post-filter 1DGD-5005 Rating: Pre-filtration 50 micron, Post- filtration 5 micronFlow rate: 10 Gpm (38 Lpm) @Material Filter Media- Polypropylene FibersOperation ratings- Temperature rating: 4ºC – 62ºCPacking and Shipping4pcs x Filter Cartridge DGD-2501/DGD-5005 Packing and Shipping by means of standard shipping packages.
