Pleated cartridge filters are surface filters that prevent sediments from passing though the surface. The cartridge media is pleated, so that the surface area of the filter increases and holds a large amount of sediments. The pleated media is engineered to form layers that enable absolute filtration while also allowing it to capture particles of different sizes. Therefore – It aids fine filtration in both nominal and absolute filtration efficiency. The micron rating of pleated cartridge filters is more precise than string wound or melt blown variants – hence it is the popular choice for critical applications and production of high-purity and sterile water.
