The two gradient cartridge for water filters has a multicomponent structure: a polypropylene thread is wound around the core of a polypropylene fiber made by pneumatic extrusion.
The inner core of polypropylene fiber usually has a half-lower filtration rating and prevents particles from being washed away from the surface filter layer wound from polypropylene filament. The inner layer itself has a bi-gradient filtration rating of 10 to 5 microns. Therefore, this combined filter cartridge for water filters has a total filtration rating of 20/10/5 microns.
The retained particles of contaminants are evenly distributed from the outside inward through the thickness of the filter material, thereby providing an increased cartridge life for water.
Operating temperature – “+2 – +43 C;
The filtering material is polypropylene fiber, polypropylene thread;
Filtration rating – from 20 microns to 5 microns
