Pleated filter can be divided into candle filter and cartridge filter. There are mainly two kinds of materials for the pleated filter: stainless steel woven wire mesh and stainless steel sintered fiber felt which is made of stainless steel fiber by sintered in high temperature. Apart from the pleated filter, there is a type of filter protected by square perforated metal mesh or fastened by wire mesh in the surface, which is more strength and an ideal alternative to filter gas or liquid. Due to its pleated structure and raw material, pleated filter has the advantages of large filter area, smooth surface, firm structure, high porosity and good particle holding capacity, etc.
