Filter Press Filter Cloth: Filtration Forms & Opening Methods By Shanghai Junyi Filter Equipment Co., Ltd.
Filter presses achieve solid-liquid separation using filter media -- filter cloth, filter paper, and filter aids. Among these, filter cloth is the most widely used and critical component. At Shanghai Junyi Filter Equipment Co., Ltd., we can provide high-quality filter cloth solutions tailored to all types of filter presses. This guide breaks down the main filter cloth structures and their opening methods to help you choose the right product for your process.
- Chamber Filter Cloth (Sleeve Type Filter Cloth)
Also known as sleeve-style filter cloth, this is the most common type for chamber filter presses. A full sheet of filter cloth is cut into two identical pieces and processed into one piece .
Feed Port Configurations: Central feed, top feed, corner feed, side feed, and eccentric feed to match different process flow designs.
Filtrate Discharge Options: Open flow (visible liquid discharge) and closed flow (piped liquid discharge) for different environmental and hygiene requirements.
Washing Capabilities: Available in washable and non-washable versions to support cake washing processes in applications like chemical, food, and pharmaceutical industries.
Our chamber filter cloths are precision-manufactured to perfectly fit standard and custom chamber filter press models, ensuring consistent filtration performance and long service life.
- Plate and Frame Filter Cloth
Designed specifically for plate and frame filter presses, this type uses a single continuous piece of filter cloth, eliminating the need for sewn sleeves.
Key Feature: Holes are heat-sealed according to the exact feed port position of the filter press, ensuring perfect alignment.
Unfolded Size Calculation: (Filter plate side length + 60mm + plate thickness) × 2
Advantages: Simple processing, cost-effective, and compatible with most standard plate and frame filter press models.
Ideal for general-purpose filtration applications where straightforward, reliable performance is required.
- Sealed Filter Cloth (Leak-Proof Filter Cloth)
This advanced filter cloth design features a sewn sealing strip around its perimeter, which fits snugly into the inner edge of the filter chamber.
Zero Leakage Performance: The embedded design completely avoids washing and filtrate ports, with no exposed filter cloth, achieving a "water-tight" seal for critical applications.
Single Opening Design: No separate filtrate or washing holes are required—only the feed port is opened, simplifying installation and reducing potential leak points.
Perfect for High-Purity Applications: Ensures all solid-liquid separation occurs within fully sealed chambers, making it ideal for industries requiring strict hygiene and zero cross-contamination, such as chemical processing and wastewater treatment.
