Filter press cloths or filter panel cloths are specialized filter media used in filter press machines, which are widely employed across industries for solid-liquid separation. These cloths act as the primary barrier that captures solids while allowing clean filtrate to pass through, making them an essential component in industrial filtration systems.
Material | Micron Rating | Advantages | Limitations |
---|---|---|---|
Polypropylene (PP) | 1 – 200 µm | High chemical resistance, lightweight, economical, easy to clean | Limited temperature resistance (up to 90–110°C) |
Polyester (PET) | 1 – 100 µm | Good abrasion resistance, stronger than PP, handles higher temperature (up to 150°C) | Less chemical resistance than PP |
Polyamide (Nylon) | 10 – 100 µm | Excellent mechanical strength, flexible, good for fine particles | Lower resistance to acids and alkalis |
Cotton | 20 – 100 µm | Natural fiber, biodegradable, good for non-aggressive slurries | Low chemical and temperature resistance, short lifespan |
