Water Filter Cartridges  - Wound Cartridge

Wound cartridges are designed to meet the most demanding filtration duties. They offer an economic, compact, easily installed and maintained filtration system for removal of particulates from liquid. Wound cartridges are manufactured from a variety of carefully selected raw materials. After carding & spinning into roving they are wound into cartridges with carefully controlled micron rating. From raw materials to finished products we are in control of the quality and filtration characteristics. String wound cartridge filter is a kind of deep filter cartridge, which is made of the textile fabric string (polypropylene, absorbent cotton and so on) preciously winding onto the multihole axies according to the specific technology. The typical honeycomb structure of the filter body gives it a considerable capacity for accumulating impurities present in the fluid being filtered. The larger foreign particles are filtered out on the surface, while smaller particles are blocked later in the inner filtering substance.

Operation of Wound Catridge

Unfiltered fluid passes through depth filter matrix, which enables the progressive retention of finer particles, providing high efficiency, high dirt retention & long filter life. Fluid flows from outside to inside through filter media. Particulates are held securely in the filter matrix and clean fluid flows to the downstream side of cartridge.
