Common Problem
Short Filter Lifespan
Frequent filter cloth replacements drive up costs and downtime. Identifying the degradation mechanism is key to extending service life.
The Problem
A filter cloth that wears out prematurely represents a significant cost factor — not only in replacement material but also in unplanned downtime, labour, and lost production capacity.
Premature failure can manifest as holes, thinning, loss of tensile strength, or deformation. The root cause may be chemical, mechanical, thermal, or a combination of stresses acting on the fabric simultaneously.
Typical Causes
- Chemical attack from acids, alkalis, or oxidising agents in the slurry
- Abrasion from sharp or hard particles (e.g., mineral processing)
- Thermal degradation when operating above the fabric's temperature limit
- Hydrolysis in high-temperature, high-pH environments
- Mechanical stress from plate closure, high-pressure differentials, or improper handling
- UV exposure in outdoor installations without proper protection
R+F Solutions
We select materials and fabric constructions matched to your specific degradation profile — extending service life and reducing total cost of ownership.
Chemical-Resistant Materials
PP for acids, PA for mild alkalis, PEEK for extreme chemical and thermal environments. We match the polymer to your process chemistry.
Reinforced Construction
Reinforced edges, double-layer weaves, and heavy-duty seams extend cloth life in high-abrasion and high-pressure applications.
Temperature-Rated Fabrics
We offer fabrics rated for continuous operation from ambient up to 260°C (PEEK), ensuring thermal stability throughout the service life.
