The main filter material of the corrugated candle filter element is made of stainless steel fiber sintered felt and stainless steel woven mesh. Stainless steel fiber sintered felt is a kind of porous deep filter material made of stainless steel fiber after high temperature sintering. The corrugated filter element made of it has the characteristics of high porosity, large filtration area, strong dirt holding capacity and strong reusability. , the stainless steel woven mesh is woven by stainless steel wire. The filter element has the characteristics of good strength, not easy to fall off, easy to clean, high temperature resistance, and economical use. It is mainly used for high molecular polymers and medicines, hydraulic oil, water treatment, high temperature gas Filtration of other media.
