Our 4.5" diameter SDF filters have true multi-stage depth filtration integrated into their design. Utilizing our technology to create 4 separate layers of micron filtration, our outside-in flow allows the outer layer to trap the larger sized particles, resulting in a much lower pressure drop compared to conventional filters.
SDF SERIES SEDIMENT DEPTH FILTERS

Our 4.5" diameter SDF filters have true multi-stage depth filtration integrated into their design. Utilizing our technology to create 4 separate layers of micron filtration, our 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, our SDF filters provide a much higher dirt holding capacity than standard spun polypropylene and string wound cartridges. They are also used in applications such as Ice Machines, Film Processing, Beverage, Coffee, Analytical, Wineries, and many others.
