PRODUCT INTRODUCTION
Wire‑wound filter elements are depth‑type filters for low‑viscosity, low‑impurity fluid filtration. Textile fiber yarns (polypropylene, degreased cotton, etc.) are precisely wound onto porous polypropylene or stainless‑steel skeletons, forming a honeycomb structure loose outside and dense inside to trap suspended solids, particles, rust and other contaminants. Proper winding controls yarn thickness and tension to achieve an outer‑loose‑inner‑dense gradient, boosting filtration efficiency and contaminant holding capacity via depth‑filtration performance.
Its filtration accuracy depends on yarn thickness and winding density. Finer yarn or tighter winding delivers smaller pores and higher precision. Meanwhile, the filter medium shall retain stable structure and pore size throughout operation for consistent filtration performance.
PRODUCT FEATURES
High accuracy, large flow, low ΔP, high dirt‑holding, pressure‑resistant, non‑toxic, pollution‑free.
High accuracy, low pressure drop, large flow, high dirt‑holding capacity, long service life.
Inner‑small outer‑large pores for excellent depth filtration.
Various element materials for optimal performance with different liquids.
Product Principle
Wound filter cartridges are formed by winding fiber yarn around a perforated support core in a specific pattern. By controlling the winding density during production, cartridges with different filtration ratings can be manufactured. The filter pores are designed to be larger on the outside and smaller on the inside, providing excellent depth filtration performance. Wound cartridges effectively remove suspended solids and particulates from liquids, offering high flow rates, low pressure drop, high dirt-holding capacity, and long service life. They can withstand relatively high filtration pressure. Depending on the properties of the liquid being filtered, a variety of yarn materials are available to ensure good compatibility between the cartridge and the filtrate.
