Filter cloths for filter press

Filter press fabrics are essential components in this type of device and play a key role in the filtration process. They are placed between the filter plates and have the function of retaining solid particles while allowing the liquid to pass through them.
Finsa JOB | Group offers a wide range of filter press fabrics, adapting them to the different types and sizes of both chamber and membrane filters.

Fabrics with different finishes

Fabric finishes are manufactured providing customized solutions, preferred by both industries and OEMs. They can be single, double or straddle depending on the specific filtration requirements for each application. Double or straddle filtration fabrics tend to be more efficient given the ease of installation when the type and dimensions of the equipment allow it. Otherwise, single filtration fabric is used as an alternative in these applications where the installation of the above fabrics is not feasible. On the other hand, below are the different finishing options that we can offer on our fabrics:

  • Fabrics with support fabric
  • Collars (standard, semi-reinforced and reinforced; made of fabric, PVC or rubber)
  • Metal eyelets
  • Velcro closures to attach to the plate
  • Reinforced frames
  • Glued frames
  • Reinforcements on the studs
  • Leaktite® solutions for CGR plates

Manufacturing process of our filter fabrics

Collars

Collar types vary depending on the product being filtered, temperature, pH, washing process and the materials the plates are made of. Collars are an important part of the filtration process, essential to ensure proper sealing and prevent leakage during filter press operation. Their main function is to ensure a tight and efficient connection between the filter press plates, ensuring that only liquid passes through the filtration system while retaining solid particles.
Selecting a suitable collar is crucial to ensure optimal solid-liquid separation performance. Options include:

  • Standard collar
  • Waterproof PVC collar
  • Semi-reinforced collar
  • Reinforced collar
  • Rubber collar (we have up to 50 moulds available in different sizes)
