Different filters are used in water treatment, high flow filter cartridge is one of frequently-used fitlers.
it has a 6 inch/152mm large diameter, and is coreless, single open-ended with an inside to outside flow pattern.The large diameter with big filter area insures to reduce the number of filter cartridges and the dimention of housing required..The long service life and high flowrate result in low investment and less manpower  in many applications
Gradient pore structure
Up to 110M3/H flowrate per filter cartridge for water filtration.
Maximum 50% reduction of filter system
20.69 inch /525mm,40.69inch/1033mm and 60.69 inch/1541mm lengths are available
All contaminants can be removed within the cartridge because of the flow direction.
