HFSW2 Double Seal
HFSW2 Double Seal high flow filter cartridge is a replacement cartridge for the depth filtration and other 2-1/2″ diameter cartridges for the high flow applications, such as reverse osmosis pre-filtration and similar applications that nominal efficiency can meet corresponding requirements. The flow rate of 60″ filter cartridge is as high as 60 m3/h, which significantly reduce the number of filter cartridges and housing dimensions.
The treatment capacity of a HFSW2 Double Seal filter cartridge is equivalent to that of 10 pcs filter cartridges with an outer diameter of 2-1/2″ and a length of 40″.
