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.

Salient Features of Wound Catridge

Filtration rating from 1 to 100 Micron

High strength & pressure resistance

Full range of sizes from 10” to 40” Length

Excellent flow with low pressure drop

High dirt holding capacity

Compatible with a wide range of fluids

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.
