Efficient filtration for metalworking and grinding systems
In modern manufacturing, the purity of the coolant determines the quality of the final product. Our filter fleece (available as a roll ) is specifically designed for use in belt filter systems . Whether turning, milling, or grinding – the right belt filter fleece ensures that particles and chips are reliably removed from the coolant . This allows you to sustainably reduce your maintenance costs and increase the efficiency of your entire system.
Viscose filter fleece or PP filter fleece:
The right material for your process. Depending on the filtration performance requirements, we offer different material compositions:
- Viscose fleece roll (30g & 50g): Ideal for drilling and milling centers . The viscose filter fleece is perfectly suited for standard filtration of emulsions and cutting oils. Our 50g roll of viscose filter fleece is the all-rounder for collecting metal chips in classic belt filter systems .
- PP filter fleece (20g & 150g): Polypropylene (PP) is characterized by its high chemical resistance. While the lightweight 20g PP filter fleece roll is particularly strong when wet and tear-resistant for medium-sized particles, our heavyweight 150g PP filter fleece offers true 3D depth filtration .
Special solution: Filter fleece roll for grinding machines
Especially in grinding processes, fine filtration is crucial for surface quality . Our filter fleece for grinding machines (150g PP) is designed to bind even the smallest sludge particles deep within the material. This fine filtration prevents clogging of the grinding wheel and protects your pumps in the long term.

Frequently asked questions about filter fleece and belt filter systems
Here you will find answers to the most important questions about filter fleece rolls and belt filter systems. Benefit from our over 50 years of experience in cooling lubricant filtration. If your question isn't answered here – simply contact us directly!
The choice of the right belt filter fleece depends on the type of contamination and the coolant/lubricant used. For standard turning and milling applications, viscous filter fleece (30g or 50g) is usually used because of its high absorbency. For more aggressive media or when high tear resistance is required, PP filter fleece is recommended. For grinding machines , a heavy fleece (e.g., 150g PP) is the best choice for fine filtration .
Viscose fleece consists of natural fibers, is highly absorbent of emulsions, and offers good depth filtration of standard particles. PP filter fleece (polypropylene), on the other hand, is more chemically resistant, extremely wet-strength , and tear-resistant . While viscose is often the all-rounder, PP filter fleece excels in special applications such as 3D depth filtration or very fine grinding dust.
A high-quality filter fleece continuously removes chips, abrasion particles, and foreign oils from the circuit. This keeps the coolant clean, reduces bacterial contamination, and maintains consistent cooling performance. Effective filtration using the right belt filter fleece thus reduces the need for refills and significantly lowers your maintenance costs .
Grinding produces extremely fine particles (grinding sludge) that can quickly clog standard nonwoven fabric. A special filter fleece for grinding machines, such as our 150g PP fleece, enables 3D depth filtration . This means the particles are not only trapped on the surface but throughout the entire structure of the fleece roll . This guarantees a higher surface quality for the workpieces and protects the high-pressure pumps in your system.
Our nonwoven rolls for belt filter systems are available in various standard widths and lengths to fit all common system types. Whether narrow belts for mobile systems or wide rolls for central coolant cleaning systems – we supply the right configuration for your needs.
