150 g/m² Filter Fleece Roll – Belt Filter Media for Grinding Systems (P150)
Maximum Filtration Performance for Precision Manufacturing Processes
The WINKLER P150 filter fleece (150 g/m²) has been specifically developed for applications requiring exceptionally clean coolants and process fluids. Grinding operations generate extremely fine particles that standard filter media often cannot remove efficiently. The P150 belt filter fleece enables highly reliable filtration and supports stable manufacturing processes even under the most demanding quality requirements.
Thanks to its high material weight of 150 g/m², the filter fleece offers outstanding dirt holding capacity. Particles are retained not only on the surface but also deep inside the fleece structure. This enables significantly longer service life and reduced maintenance intervals.
The filter fleece was specifically designed for demanding applications in grinding systems and precision machining operations, but it can also be used in other belt filter systems whenever extremely fine filtration is required.
Typical Applications
The P150 filter fleece is primarily used in applications where maximum purity of process fluids is essential:
- Grinding systems and grinding centers
- Precision engineering and high-precision machining
- Machining of aluminum, steel and cast iron
- Filtration of coolants containing high concentrations of fine particles
The high filtration efficiency ensures that even microscopic particles are reliably separated while maintaining stable production processes.
This heavy-duty PP nonwoven material is a specialized solution within our range of filter fleece rolls for belt filter systems. It was developed for the extreme requirements of the metalworking and electronics industries, where it provides highly reliable depth filtration even with large chip volumes and demanding machining conditions.
How Belt Filter Fleece Works
The contaminated medium flows across the filter fleece where solid particles are retained. The cleaned liquid can then be recirculated back into the production process.
Filter fleece media with high material weights provide exceptional dirt holding capacity and are particularly suitable for applications involving fine particles or high purity requirements.
The voluminous nonwoven structure creates an effective 3D depth filtration effect, allowing particles to be trapped not only on the surface but throughout the material itself. This ensures stable filtration performance over extended operating periods.
Your Advantages in Industrial Applications
The P150 filter fleece has been engineered for demanding industrial environments and enables highly efficient cleaning of coolants and industrial process fluids.
- Maximum Filtration Efficiency: Ideal for separating extremely fine particles.
- High Dirt Holding Capacity: Enables extended operating times and fewer filter changes.
- Stable Production Processes: Cleaner media improve machining quality and surface finishes.
- Reduced Wear: Protects tools, pumps and machinery components.
- Optimized for Grinding Systems: Designed for highly demanding filtration applications.
Which Filter Fleece Is Right? Material Weight Comparison
The appropriate material weight depends on particle size, contamination levels and required flow rates. The following overview helps compare the different filter fleece options:
| Filter Media | Material Weight | Filtration Type | Typical Application |
| P20 PP | 20 g/m² | Coarse filtration | High flow rates and coarse particles in belt filter systems. |
| V30 Viscose | 30 g/m² | Standard filtration | Universal coolant filtration for CNC machining systems. |
| V50 Viscose | 50 g/m² | Fine filtration | Fine metal particles and extended coolant service life. |
| P150 Polyester | 150 g/m² | 3D depth filtration | Highest purity for grinding processes and precision applications. |
Whenever extremely fine particles must be separated or the highest purity standards apply to process liquids, the P150 filter fleece is typically the optimal solution.

FAQ – Filter fleece roll 150 g/m² for grinding machines
Frequently asked questions about the P150 filter fleece for belt filters and precision filtration
The 150 g/m² polyester filter fleece was specially developed for applications requiring the reliable separation of the finest particles while simultaneously demanding a high dirt-holding capacity. Particularly in grinding processes and precision machining, this belt filter fleece ensures stable filtration performance and significantly improved purity of cooling lubricants and process fluids.
What is a filter fleece with a weight of 150 g/m² used for?
Typical applications include grinding of steel, aluminum or cast iron, as well as machining processes with high surface quality requirements.
Due to its high grammage, the filter fleece is particularly suitable for heavily loaded filter systems.
What are the advantages of a heavy filter fleece like P150?
The voluminous structure enables depth filtration, in which particles are bound not only on the surface but throughout the entire nonwoven fabric.
This allows the filtration to remain stable for longer and the maintenance intervals to be reduced.
For which belt filter systems is the P150 filter fleece suitable?
It is particularly frequently used when cooling lubricants are heavily contaminated with fine particles or when very clean process fluids are required.
The filter fleece can be adapted to many systems thanks to different roll widths.
When should a filter fleece with a weight of 150 g/m² be chosen?
Especially in grinding processes or with high quantities of solids, the high basis weight ensures better filtration and longer service life.
In applications with low levels of dirt ingress, a lighter nonwoven fabric may be more economical.
How does the P150 filter fleece differ from lighter filter fleeces?
Compared to lighter nonwovens, it offers significantly higher dirt absorption and finer filtration.
This makes it particularly suitable for precision processes and systems with high particle loads.
