Liquid Filter Bag BLD
The BLD series liquid filter bags adopt premium polypropylene, polyester, nylon and other filter materials, manufactured in accordance with specific working conditions and application requirements. The surface can be finished with singeing, calendering or membrane treatment to effectively prevent fiber sheddinga nd filtrate contamination. The fluffy and uniform three?dimensional filtering layer delivers excellent capture performance for solid particles and colloids. High?strength long fibers ensure stable filtration efficiencya nd a longer service life. Featuring high retention rate, strong dirt holding capacity, large flow rate and outstanding pressure resistance, they are widely applied for liquid impurity removal and filtration across various industries.
