Filter Cloth for Filter Press 20 µm – F-TEX Brillant sun (6L) for Precision Pressure Filtration
A Fine Filter Cloth for Stable Filtration Cycles and Clear Filtrate
The WINKLER F-TEX Brillant sun (6L) Filter Cloth is a fine filter cloth for filter presses, developed specifically for applications that need very good filtrate clarity alongside cost-effective filtration cycles. With a 20 µm micron rating, this fabric delivers precise solids retention combined with stable permeability.
The combination of monofilament and multifilament yarn creates a balanced mix of particle retention, throughput and mechanical stability, making the F-TEX Brillant sun particularly well suited to industrial pressure filtration under consistent process conditions.
When Does a 20 µm Filter Cloth Make Sense?
The F-TEX Brillant sun (6L) is ideal when filtrate quality and stable filtration cycles are equally important:
- Reliably retaining fine solids without unnecessarily long cycle times.
- High filtrate quality for industrial suspensions.
- Stable pressure filtration with reproducible results.
- Low tendency to clog under varying loads.
This yellow filter cloth was developed for precision filtration tasks. Within our range of premium filter cloths, it's a specialised solution for demanding separation processes in the chemicals & raw materials sector.
Precise Fabric Construction for Controlled Filtration
The F-TEX Brillant sun stands out for its especially high fabric density. With 110 warp threads per centimetre, it creates an even pore structure that enables precise, reproducible filtration.
This defined structure delivers stable filtration properties across the full service life of the filter cloth and reduces variation in filtrate quality.
Calendered Surface for Optimised Cake Release
In many applications, cake release largely determines the filter press cycle time. The F-TEX Brillant sun features a calendered surface that creates an especially smooth fabric structure.
- Improved cake release: The filter cake separates evenly from the cloth.
- Shorter cycle times: Faster emptying of the filter chambers.
- Less cleaning effort: Fewer manual interventions.
- Stable filtration: Even permeability over a long period.
Mechanical Stability and Long Service Life
With a fabric weight of 490 g/m², the F-TEX Brillant sun offers high mechanical strength for industrial pressure filtration. The fabric stays dimensionally stable even across repeated press cycles, ensuring reliable sealing of the filter chambers.
Its robust construction supports long service life and reduces unplanned cloth changes.

FAQ – Filter Cloth for Filter Press 20 µm (F-TEX Brillant sun 6L)
Common Questions About Fine Filter Cloths for Stable Pressure Filtration Filter cloths with a 20 µm micron rating are often used when high filtrate quality needs to be combined with cost-effective filtration cycles. In the filter press, the filter cloth retains solids while liquid is pressed through the fabric under pressure and exits as filtrate.
