Filter Cloth for Filter Press 25 µm – F-TEX Classic (7L) for Cost-Effective Pressure Filtration
A Proven Standard Filter Cloth for Reliable Solid-Liquid Separation
The WINKLER F-TEX Classic (7L) Filter Cloth is a proven filter cloth for filter presses, built for reliable, cost-effective solid-liquid separation. With a 25 µm micron rating, it delivers a balanced combination of secure particle retention, stable permeability and long service life.
As a versatile standard solution, the F-TEX Classic is particularly well suited to industrial wastewater and suspensions with medium particle sizes. The robust multifilament polypropylene fabric ensures stable filtration cycles and even dewatering of the filter cake.
When Is a 25 µm Standard Filter Cloth the Right Choice?
The F-TEX Classic (7L) is particularly well suited to applications where cost-effective, reliable filtration is the priority:
- Standard wastewater filtration in industry and production.
- Stable dewatering for suspensions with medium particle sizes.
- Predictable service life and low operating costs.
- Robust pressure filtration with regular press cycles.
As a robust standard cloth, this model is a key part of our range of filter cloths for chamber filter presses. It's a preferred choice for filtering process waters and sludges in the chemicals & raw materials industry, where reliability and durability are critical.
Multifilament Fabric for Even Filtration
The F-TEX Classic is built on a multifilament fabric construction that ensures an even pore structure and high mechanical stability. The fine individual fibres deliver reliable particle retention and consistent filtrate quality.
This fabric structure enables controlled solid-liquid separation with good permeability, resulting in cost-effective filtration cycles.
Calendered Surface for Stable Filtration Cycles
The calendered surface creates an even fabric structure and improves filter cake release after the pressing cycle. This keeps filtration properties stable even over long service periods.
- Even cake release: The filter cake separates cleanly from the fabric.
- Consistent permeability: Even filtration over long service life.
- Reduced maintenance: Less cleaning effort during operation.
- Stable press cycles: Reproducible filtration results.
Cost-Efficiency and Long Service Life
With a fabric weight of 280 g/m², the F-TEX Classic strikes a good balance between mechanical stability and permeability. This makes the filter cloth particularly well suited to continuous operation with predictable filtration cycles.
The combination of robust material and even fabric structure enables long service life and reduces the overall cost per filtration cycle.
