Filter Cloth for Filter Press 25 µm – F-TEX Brillant black (15L) for High-Permeability Pressure Filtration

A High-Permeability Filter Cloth for Short Cycle Times and Stable Filtration

The WINKLER F-TEX Brillant black (15L) Filter Cloth is a high-permeability filter cloth for filter presses, developed for applications where short filtration cycles and reliable dewatering are the priority. With a 25 µm micron rating, this fabric combines secure particle retention with high permeability for cost-effective pressure filtration.

The special combination of monofilament and multifilament yarn creates a robust fabric structure with stable permeability, making the F-TEX Brillant black particularly well suited to industrial filtration processes with varying solids loads or higher throughput needs.

When Does a High-Permeability Filter Cloth Make Sense?

The F-TEX Brillant black (15L) is particularly well suited to filtration processes where fast dewatering of the filter cake is critical:

• Short filtration cycles thanks to high permeability.
• Fast dewatering of the filter cake.
• Suspensions with medium particle sizes.
• Processes with fluctuating solids loads.

For processes with large volume flows, we offer this cloth within our plant filter cloth range. It's ideally suited to the requirements of the chemical industry, where fast dewatering results under high mechanical load are required.

Hybrid Fabric Construction for Stable Filtration

The filter cloth is built on a hybrid construction of monofilament and multifilament yarn. The monofilament threads provide a stable fabric structure and good release properties, while multifilament yarns support reliable particle retention.

This combination enables even filtration even under varying process conditions and reduces the fabric's tendency to clog.

Calendered Surface for Reduced Cake Adhesion

The calendered surface creates a smooth fabric structure, so the filter cake releases more easily from the filter cloth. This significantly improves chamber emptying, particularly with sticky or pasty suspensions.

• Low cake adhesion: Even release after the pressing cycle.
• Shorter downtime: Faster emptying of the chambers.
• Stable filtration: Even permeability over long service life.
• Less cleaning: Reduced manual effort.

Optimised for Cost-Effective Pressure Filtration

With a fabric weight of 320 g/m², the F-TEX Brillant black offers a balanced combination of stability and permeability. The fabric stays dimensionally stable even across repeated press cycles and supports even dewatering.

Its high permeability reduces filtration resistance and enables stable filtration cycles even with larger sludge volumes.
