String wound filter vs polypropylene These are thin, pleated filters that trap contaminants on their surface. . Feb 13, 2025 · In this blog post, we’ll delve into three common polypropylene filters used in industrial liquid filtration: nominal string wound filters, meltblown filters, and pleated absolute filters. Melt blown filters are ideal for applications requiring fine filtration and high efficiency, while string wound filters excel in durability and handling higher sediment loads. Construction: These filters consist of a core wrapped with layers of wound polypropylene string (yarn). Surface Filters. Jun 3, 2025 · String wound filter cartridge is just as they sound; material such as polypropylene in string form which is wound around a central core.
