Product Information

The Pentek 555476-43 20 Big Blue Filter Cartridge and the Pentek GD-2501-20BB have been replaced by the compatible FiltersFast FFDG-20BB-1. The FFDG-20BB-1 is a gradient density 100% pure polypropylene filter that provides superior purity without affecting color, odor or taste. This 20" cartridge has two unique layers that hold up to three times more dirt than the standard pleated, string-wound and spun polypropylene cartridges. The larger outer pre-filter of this sediment filter reduces the partial load to the inner post filter. This filtration process allows the gradient density cartridge to operate at a higher rate of speed, with a lower pressure drop.

The FiltersFast FFDG-20BB-1 compatible Filter Cartridge contains an inner support core that provides added strength and unobstructed flow. This GDA cartridge series captures particles through the entire depth of the filter media. This filtration process is popular with pretreatment applications that help to protect systems like the reverse osmosis systems.

  • Part Number: FFDG-20BB-1
  • Replaces Part Number: 555470-43, GD-2501-20BB

ThisFiltersFast FFDG-20BB-1 filter is a space-saving, two-layer cartridge that eliminates the need for purchasing additional filter canisters. The FiltersFast FFDG-20BB-1 provides superior chemical resistance and is not prone to attacks from bacteria.
