Liquatec SDF Series sediment filters are manufactured from 100% pure polypropylene fibers and graded density for higher dirt holding capacity.
The Liquatec Series 2.5" diameter SDF cartridge’s coreless design is an economical solution to pre-filtration for many applications. They are used widely as pre-filtration for RO systems and post-filtration for GAC filters. They are also used in applications such as Ice Machines, Film Processing, Beverage, Coffee, Analytical, Wineries, and many others.
Liquatec 4.5" diameter SDF filters have true multi-stage depth filtration integrated into their design. Utilizing technology to create
4 separate layers of micron filtration, outside-in flow allows the outer layer to trap the larger sized particles, resulting in a much lower pressure drop compared to conventional filters.
Trapping various
sized particles layer-by-layer, SDF filters provide a much higher dirt holding capacity than standard spun polypropylene and string wound cartridges.
