This Liquatec SDF-45-2020 20" Big Blue Sediment Filter is being discontinued and will be replaced by the Hydronix SDC-45-2020 Filter.
The Liquatec 20" x 4.5" Sediment Filter (SDF-45-2020) is a 20 Micron sediment water filter cartridge made of 100% pure polypropylene fibers that will reduce the amount of sediment, sand, dirt, rust, silt, and other impurities in your water. These Liquatec Sediment Depth Filter (SDF) Series water filter cartridges feature a coreless design and are an inexpensive solution to pre-filtration for whole house water filters as well as various commercial applications.
Typical home and small business applications for the Liquatec SDF-45-2020 polypropylene filter (also known as a PP filter) include potable water, beverages, wineries, ice machines, post-filtration for GAC filters, and more. Industrial uses of this Liquatec sediment filter include pre-filtration for manufacturing, pre-filtration for fine and low viscosity chemicals, water recycling, film processing, electroplating, etching, image developing processes, plus more.
These Liquatec sediment water filter replacement cartridges are made of 100% high purity polypropylene fibers which are adhesive free, binder free, and surfactant free, and they are of a graded density for higher dirt holding capacity. The Liquatec Sediment Depth Filter Series (4 1/2" diameter) water filter cartridges are designed for high chemical resistance and feature multi-stage sediment depth filtration. These Liquatec sediment filters utilize technology which creates four separate layers of micron filtration, while the outside-in flow traps the larger sediment particulates which results in a lower pressure drop when compared with standard 2 1/2" diameter water sediment filters. All of the Liquatec SDF x 4.5" Series filters provide a much higher particulate filtering capacity in comparison to standard spun polypropylene and string wound water filter replacement cartridges.
This Liquatec sediment filter is a compatible replacement water filter cartridge that fits industrial and whole house water filter housings which use 20" x 4 1/2" replacement filters.
Liquatec SDF-45-2020 Sediment Filter Cartridge Specifications:
Filter life depends on specific water quality and usage. This Liquatec water filter should be changed when a decrease in pressure is noticed. The replaceable pressure drop recommended by the manufacturer is 21.75 PSI.
The Liquatec SDF-45-2020 is FDA Approved for use in food service applications. It was also tested and certified by NSF International under NSF / ANSI Standard 42 for material requirements only.
