The Highest-Capacity Depth Filtration with the 40 inch 5 Micron String Wound Filter
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
On a Large Line, Capacity Decides Everything
Problem
Frequent Downtime, Rising Cost
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 Longest Body, the Least Downtime
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
Wound, High-Capacity, Durable
The 40 inch 5 Micron String Wound Filter is the first filtration stage of an industrial line.
5 Micron Filtration
Holds back sand, rust, silt and limescale particles larger than 5 micron.
Graded Winding Structure
Yarn winding that tightens from outside in delivers depth filtration and high dirt-holding capacity.
The Highest Holding Capacity
A 40 inch body can accumulate far more sediment than shorter cartridges.
Supported Core
The core structure helps the cartridge hold its shape under pressure.
Multi-Cartridge Compatibility
Capacity can be increased by running several cartridges together in industrial housings.
Wide Application Range
Widely used for the pre-filtration of process liquids as well as water.

Product Details
| Feature | Value | What it does |
|---|---|---|
| Product Type | String Wound Sediment Filter | Which family the unit belongs to. Products in the same family can be used in place of one another. |
| Size | 40 inch (40") | 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. |

05How It Works
How Does the 40 inch 5 Micron String Wound Filter Work?
Fitted into the Housing
The cartridge is fitted into the single or multi-cartridge 40 inch housing at the first stage of the line.
Water Enters the Wound Layers
Water from the line travels inwards through the loose outer winding on the cartridge’s surface.
Captured in Depth
Coarse particles are held in the outer layers, fine particles in the progressively tighter inner windings.
Clear Water Continues On
Freed of sediment, the water is collected in the core cavity and passed to the next stage.
The Pressure Differential Is Watched
When the inlet–outlet pressure differential rises, the cartridge is saturated; that is when it is replaced.
06Making the Right Choice
40 inch or 30 inch?
When choosing the 40 inch 5 Micron String Wound Filter, consider the housing size, the flow rate and the number of cartridges together.
Housing Size
This cartridge is for 40 inch housings; shorter housings take 10, 20 or 30 inch cartridges.
Line Flow Rate
As flow rises, a longer cartridge or several cartridges together become necessary.
Construction Choice
String wound is strong at depth filtration; spun filters are generally more economical.
End Type
The cartridge end configuration (flat or with adaptor) must match how the housing seats it.
07Maintenance and Use
Replacement Notes
With regular monitoring, the 40 inch 5 Micron String Wound Filter keeps the line running without interruption.
- This cartridge is not washable; sediment penetrates the depth of the winding and cannot be flushed out.
- Watch the inlet–outlet pressure differential regularly; a marked rise signals that replacement is due.
- In multi-cartridge housings all cartridges should be replaced together; mixing old and new lowers efficiency.
- Before replacement, shut off the line, release the pressure in the housing and check the condition of the gasket.
08Frequently Asked Questions
Common Questions
What does the 40 inch 5 Micron String Wound Filter do?
It holds back suspended solids such as sand, rust, silt and limescale particles. Its industrial-length body and wound structure provide depth filtration on high-flow lines.
How does it differ from a 30 inch cartridge?
The difference is length. A 40 inch cartridge offers a larger winding surface and greater sediment-holding capacity, which means a longer replacement interval on high-flow lines.
How does it differ from a spun filter?
The difference is in how they are made. A spun filter is formed from melt-blown fibre in a single piece; a string wound filter is made from polypropylene yarn wound around a core. String wound is strong at depth filtration.
Can it be used in multi-cartridge housings?
Yes. In industrial housings several cartridges work together to raise system capacity. The number of cartridges is set by the flow requirement of the line.
When should it be replaced?
A rise in the inlet–outlet pressure differential and a fall in flow are the most reliable indicators. The interval depends on how dirty the water is and on the flow rate of the line, and it shortens where the sediment load is heavy.
