PP melt-blown filter is also called melt-blown filter. Is the use of non-toxic and tasteless polypropylene particles, melt-blown filter core is made of a variety of tubular deep filter core after melting, spraying, traction, receiving. PP melt-blown filter core structure is the outer fiber thick, inner fiber fine, outer loose, inner tight gradual diameter gradually compact structure. Unique gradient deep filtration forms the effect of three-dimensional filter slag, with high porosity, high interception rate, large amount of pollution, large flow, low pressure drop characteristics. It is not only used in large quantities for water purification, but also has outstanding chemical compatibility. Suitable for strong acid, strong alkali and organic solvent filtration. It has strong fouling capacity, long service life and low cost. Filter length: 10", 20", 30", 40". Filtering accuracy: 1μm, 3μm, 5μm, 10μm, 20μm, 30μm, 60μm.
