Zswf-powder felt metal film is made of porous metal film with asymmetric structure, which is composed of micrometer metal powder and high strength metal mesh supporting body by calendered process.

ZSWL- metal powder felt film asymmetric structure is a precision filter layer, a transition layer and a support body, the special structure to achieve high precision, high permeability filtration performance, to achieve high efficiency and low resistance filtration performance, filter wind speed up to 0.8-1.2m/min, filtration accuracy of 0.1μm, meet 99.999% dust removal efficiency. The high-strength wire mesh support body realizes the high tensile strength and flexibility of the metal powder felt film, and the tensile strength can reach 1400N/(50*200mm), which can meet the working life of more than 5 years.
