It is fusing and intertwined of polypropylene resin without any chemical glues. The cartridges are glued at random to form 3D micro pore which will make the cartridge 3 layers with fine fibers in surface and coarse fibers and deep filtration. As the fiber and density form high filtration rating and pollutants holding capacity on diameter of filter cartridge, low pressure drop, gradual changing deep filtration structure with loose our side and close inner, strong pollutants holding capacity, it can remove contaminant effectively, such as suspended substance, particulate and rust, providing efficient filtration and long service life. Feature: 1.Three layers structure cartridge offers high dirt holding capacity,longer service life 2.Formed by thermal bond without using any binders and adhesives. 3.100% Pure Polypropylene will not cause any pollution to water 4.Wide Chemical compatibility 5.Groove design to extend the filtration surface area 6.All kinds of adapters are available. --Drinking water treatment --Electronic --Industrial water treatment --Plating --Chemicals,solvents Specifications: Outside Diameter: 63mm,115mm or up to customers' request IInside Diameter 28mm,30mm Length: 5'',10'',20'',30'',40'',50'',60'' Filter media and End Caps Polypropylene (PP) Core: Polypropylene (PP) Gaskets/O-ring : Silicone,EPDM,NBR,Viton Removal Rating: 1.3.5.10.25.50.75.100.150um Maximum Operating Temperature: 82Deg.
