Types of Filter Press Cloth and Selection Guide

In the filtration process of a filter press, the filter cloth is the key medium for achieving efficient solid-liquid separation. Choosing the right filter press cloth not only improves filtration efficiency but also extends the service life of the equipment. In this article, we will introduce the common types of filter press cloth from three dimensions: structure, material, and weave pattern.

Types of Filter Press Cloth

1. Classification by Installation Style

Barrel Neck Filter Cloth
The feeding port is reinforced by stitching, making it easy to install and replace. This type is suitable for most industrial filtration scenarios.

Recessed Filter Cloth
The cloth is tightly embedded in the filter plate, offering excellent sealing performance. Ideal for applications with strict leakage control requirements.

Drape-over Filter Cloth
Draped directly over the filter plate, it allows for quick installation and convenient replacement.

2. Classification by Material: Three Common Types

Polyester Filter Press Cloth (PET Filter Cloth)
Excellent acid resistance, abrasion resistance, and high-temperature tolerance.

Polypropylene Filter Press Cloth (PP Filter Cloth)
Low density, strong alkali resistance, and fast filtration speed. Common in chemical, metallurgy, and municipal applications.

Nylon Filter Press Cloth (PA Filter Cloth)

Known for its outstanding abrasion resistance and flexibility.

3. Classification by Weave Pattern

Satin Weave
Smooth surface with high filtration precision. Ideal for fine chemical and pharmaceutical applications.

Twill Weave
High mechanical strength and good air permeability. Suitable for working conditions requiring both strength and efficiency.

Plain Weave
Tightly woven and cost-effective. One of the most commonly used weave structures.

Nonwoven Filter Material
Made without traditional textile weaving, offering excellent particle retention.
