The microporous pleated filter Cartridge uses multi-layer polypropylene non-woven fabric, which leads to the gradient filtration effect. It has the features of high flux, high compatibility and high fouling resistance. It can intercept particulate matter for graded size, and effectively avoid the surface blockage to improve the service life of the filter cartridge. It is suitable for high suspended particles, colloidal substances, high viscosity liquid filtration, and has widely used in clarification and filtration of biomedicine.
