It has various porosity (28%-50%), pore diameter (4u-160u) and filtration precision (0.2um-100um). The pores are crisscrossed and resistant to high temperature and rapid cooling and heating. Anti-corrosion. Suitable for a variety of corrosive media such as acids and alkalis. The stainless steel filter element can withstand general acid, alkali and organic corrosion, and is especially suitable for filtration of sulfur-containing gases. It has high strength and good toughness. It is suitable for high-pressure environments. It can be welded. Easy to load and unload. Stable hole shape and even distribution ensure stable filtration performance. Good regeneration performance. After repeated cleaning and regeneration, the filtration performance recovers by more than 90%.
