Needle felt steel ring liquid filter bag is an important part of the filtration system, relying on the filtration system fluid pressure, filtering the liquid through the filter bag.

Operated by the principle of deep filtration, the needle felt filter bag can effectively remove solid and soft particles. The liquid filter bag is specially designed to be freely installed in various incompatible filter weights with a maximum particle retention rate of 99. %, it has many characteristics of high dirt holding capacity, strong corrosion resistance, good temperature resistance, large flow, convenient operation, long service life, no fiber shedding, etc., which brings great convenience to users. It is a liquid filter bag with relatively advanced domestic technology and high comprehensive cost performance. Available in polypropylene, polyester, polyaramid and other materials and different filter bags.
Needle felt filter bags are economical and widely used in pre-filtration, amine night filtration, electrophoresis filtration, and syrup filtration.
