String Wound · Industrial Length
The 40 inch 5 Micron String Wound Filter is a depth-type sediment filter made from polypropylene yarn wound in graded layers around a porous core. As the longest of the standard cartridge sizes, it captures sand, rust, silt and limescale particles throughout its depth on high-flow industrial lines.
01Problem & Solution
Problem
On high-flow process lines, short cartridges clog before long. Frequent replacement halts production, the pressure differential grows, and the sediment load starts passing to the stages that follow.
Solution
The 40 inch 5 Micron String Wound Filter combines its long body with a graded winding structure. Particles are captured across different layers, capacity rises and the replacement interval lengthens markedly.
02Key Features
The 40 inch 5 Micron String Wound Filter is the first filtration stage of an industrial line.
Holds back sand, rust, silt and limescale particles larger than 5 micron.
Yarn winding that tightens from outside in delivers depth filtration and high dirt-holding capacity.
A 40 inch body can accumulate far more sediment than shorter cartridges.
The core structure helps the cartridge hold its shape under pressure.
Capacity can be increased by running several cartridges together in industrial housings.
Widely used for the pre-filtration of process liquids as well as water.
03Technical Specifications
| Feature | Value | What it does |
|---|---|---|
| Product Type | String Wound Sediment Filter | The product family it belongs to. When buying a spare, the family alone is not enough; the size and model must match too. |
| Size | 40 inch | The physical size. If a spare does not match this, it will not go into the housing. |
| Micron Rating | 5 Micron | The smallest particle the filter holds back. The lower the figure, the finer the sediment it catches. |
| Material | Polypropylene Yarn | What it is made of. A metal body is preferred on a pressurised line, plastic on a chemical one. |
| Filtration Type | Depth Filtration | How the filter holds material back. |
| Compatibility | 40" Filter Housings | Which units and housings it works with. Compare it with yours before ordering. |
04Applications
The 40 inch 5 Micron String Wound Filter is used on industrial-scale filtration lines.
05How It Works
The cartridge is fitted into the single or multi-cartridge 40 inch housing at the first stage of the line.
Water from the line travels inwards through the loose outer winding on the cartridge’s surface.
Coarse particles are held in the outer layers, fine particles in the progressively tighter inner windings.
Freed of sediment, the water is collected in the core cavity and passed to the next stage.
When the inlet–outlet pressure differential rises, the cartridge is saturated; that is when it is replaced.
06Making the Right Choice
When choosing the 40 inch 5 Micron String Wound Filter, consider the housing size, the flow rate and the number of cartridges together.
This cartridge is for 40 inch housings; shorter housings take 10, 20 or 30 inch cartridges.
As flow rises, a longer cartridge or several cartridges together become necessary.
String wound is strong at depth filtration; spun filters are generally more economical.
The cartridge end configuration (flat or with adaptor) must match how the housing seats it.
07Maintenance and Use
With regular monitoring, the 40 inch 5 Micron String Wound Filter keeps the line running without interruption.
