20 g/m² PP Filter Fleece Roll – Belt Filter Media for Cost-Effective Filtration
Filter Media for High Flow Rates and Coarse Filtration
The WINKLER P20 filter fleece (20 g/m²) is an economical solution for industrial liquid filtration applications. This lightweight polypropylene filter fleece is specifically designed for belt filter systems operating with high flow rates and coarse to medium contamination levels.
Thanks to its low material weight, the filter fleece provides excellent permeability while maintaining strong mechanical stability. This makes the P20 filter media particularly suitable for applications where large volumes of liquid must be filtered reliably and efficiently.
The PP filter fleece is resistant to acids and alkalis, making it suitable for a wide range of applications in metalworking, surface treatment and industrial process filtration.
Typical Applications
The filter fleece is mainly used in belt filter systems requiring reliable filtration performance combined with high throughput capacity.
- Belt filter systems in metalworking industries
- Coolant and metalworking fluid filtration
- Wash water and industrial process water filtration
- Surface treatment and finishing applications
Its high permeability makes the filter fleece especially suitable for applications involving large particle quantities or high liquid flow rates.
As a cost-efficient belt filter fleece roll, this product is ideal for standard filtration applications within the metalworking and electronics manufacturing industry. It supports stable filtration processes across a wide variety of machining applications and materials.
How Belt Filter Fleece Works
The contaminated liquid flows across the filter fleece while solid particles are retained inside the media. The cleaned liquid can then be reused or returned to the production process.
Low-weight filter fleece media provide particularly high flow rates and help belt filter systems operate efficiently even under demanding throughput conditions.
The P20 filter fleece is especially suitable for applications where coarse contamination must be separated reliably and economically.
Your Advantages in Industrial Applications
The P20 filter fleece was developed for economical industrial operation and combines reliable filtration performance with low operating costs.
- High Permeability: Ideal for filtering large liquid volumes.
- Cost-Efficient: Low material costs for economical operation.
- Durable PP Material: Mechanically strong and tear-resistant.
- Chemically Resistant: Resistant to acids and alkalis.
- Versatile Applications: Suitable for many industrial belt filter systems.
Which Filter Fleece Is Right? Material Weight Comparison
Selecting the correct filter fleece mainly depends on particle size and filtration requirements. The following overview helps compare the available filter fleece variants:
| 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 | General coolant filtration in CNC machining systems. |
| V50 Viscose | 50 g/m² | Fine filtration | Fine metal particles and extended coolant service life. |
| P150 Polyester | 150 g/m² | Depth filtration | Highest purity requirements in grinding applications. |
If large liquid volumes need to be filtered and mainly coarse particles are present, the P20 filter fleece is typically the most economical solution.

FAQ – Filter fleece roll 20 g/m² PP (belt filter fleece P20)
Frequently asked questions about the 20 g/m² filter fleece for industry and metalworking
The 20 g/m² polypropylene filter fleece is an economical solution for filtering coarse particles in belt filter systems. Due to its low weight, this belt filter fleece is particularly suitable for applications with high throughput and low operating costs, such as in metalworking or surface finishing.
What is a filter fleece with a weight of 20 g/m² particularly suitable for?
Typical applications include belt filter systems in metalworking, the filtration of cooling lubricants, or simple pre-filtration in industrial processes.
Due to the low surface weight, the flow rate remains stable, even with larger quantities of liquid.
What advantages does polypropylene offer as a filter fleece material?
The PP filter fleece is resistant to many acids and alkalis and is therefore particularly suitable for industrial process fluids such as emulsions or cleaning media.
Furthermore, the material remains stable and tear-resistant even when wet.
When should you choose a lightweight filter fleece instead of a heavy one?
For finer particles or higher requirements on filtrate quality, heavier nonwovens with a higher basis weight are usually the better choice.
This allows the filter fleece to be optimally adapted to the respective filtration process.
For which belt filter systems is the filter fleece suitable?
The rolls are available in different widths and can therefore be adapted to different belt filters.
Custom widths are also available upon request.
How does the 20 g/m² filter fleece differ from other filter fleeces?
Compared to heavier nonwovens, it allows for higher flow rates and lower material costs, while heavier nonwovens are more focused on fine filtration and dirt absorption.
