String wound filter cartridge is just as they sound; material such as polypropylene in string form which is wound around a central core. filtration of various wines, mineral water and purified water in food and beverages. Look, string wound filters are better than no filters and they are inexpensive, but a pleated filter has more surface area, traps more sediment, sand, silt and grit than any string-wound filter and are cleanable and reusable. which is accurately wound on the porous skeleton (polypropylene or stainless steel) according to a specific process. Filson melt blown filter cartridges do not require a core because the fiber is very firm itself. Except for common string wound filter cartridges with both open ends, in some cases, the string wound filter cartridges also need to have adaptors such as 222, fin, 226 end caps. The process fluids travel through the medium in a straight path and may encounter up to eight impingements on the way. All filters were challenged under identical conditions. Flexible structures, such as those found in meltblown and string-wound filters, tend to compress and change porosity with increased pressure, while rigid structures do not (Photo 1). All filters were challenged under identical conditions. The end cap welding machines SIIC-M025-SWCCEW from Shanghai INDRO Industry Co., Ltd is ideal choice for welding 222, fin, 226 end caps for string wound filter cartridges. Each of these types of filter design have their pros and cons. Saltwater Disposal. Flexible structures, such as those found in typical meltblown and string-wound filters, tend to compress and change porosity with increased pressure, while rigid structures do not (Photo 1). They offer excellent filtration and good thermal stability. Some of the . Fixed pore structure means that when the filter faces differential fluids, the polypropylene fibers do not sperate - if they sperate the trapped contaminant particles might flow into the filtrate. JMB Series Melt Blown Filter Elements String wound filters use multiple layers, wound tightly over a support core in diamond/ v-shaped patterns. They have more flexible and can be customized for special applications and environments. the highest quality in cartridge filtration. Home > Products > Filter Cartridges > PP Melt-Blown & String Wound Filter Cartridges. The melt blown cartridge filters are sturdy with a fixed pore structure. This enhanced filtration comes at the cost of surface area, meaning that depth filters usually need to be cleaned/changed quicker than pleated filters. It is made of textile fiber thread (polypropylene thread, degreasing cotton thread, etc.) Conventionally if we talk about string wound and melt blown filter cartridges, melt blown variant gets a plus one as it has a fixed pore structure. NSF/ANSI 42 Standard for Component. For instance Polypropylene is a much more sturdy construction so it will usually last longer than pleated filters.
