Its target market is 4G to 8G LCD processing, and can be used to similar applications. The large diameter creates a large surface filter area that reduces the number of filter cartridges required with a long service life and high flow rate result in low investment and less manpower costs. The cartridge has three end configurations: 83mm diameter 222 double O-ring, 83mm diameter 226 double O-ring, 131mm diameter 334 single O-ring to make it applicable for many fields. There are five types of filter media: Polypropylene Pleated, Polypropylene Melt Blown, PES membrane, PTFE membrane.
