Centre-Feed Gasketed Recessed Filter Press Cloth for Precise Sealing

Skytech Ultrafab CGR Filter Press Cloth is engineered for Centre-feed, Gasketed, Recessed-chamber filter presses — the most common filter press configuration in chemical, pharmaceutical, mineral, and wastewater dewatering applications globally. Each CGR cloth is precision-fabricated with a centre feed neck at the exact position of the plate centre hole, a gasketed perimeter that seals against the plate face, and cloth dimensions matched to the specific recessed plate used in the customer filter press.

What Is CGR Filter Press Cloth?

CGR stands for Centre-feed, Gasketed, Recessed — describing the three key construction features of this filter press cloth type. Centre-feed means the slurry inlet neck is at the centre of the cloth, aligned with the centre feed hole of a recessed plate. Gasketed means the cloth has a built-in or attached gasket material around its perimeter that seals against the plate face to prevent filtrate bypass. Recessed means the cloth is designed for a recessed-chamber plate where the recess on each plate face forms one half of the filter cake chamber.

Features and Benefits

• Precise Centre Neck Position: Feed neck cut and reinforced at the exact centre-of-cloth position to align with the plate feed hole — off-centre necks cause uneven slurry distribution and non-uniform cake thickness across the chamber
• Integrated Gasket Seal: Gasket material sewn, bonded, or moulded directly into the cloth perimeter — eliminates separate gasket installation step and ensures consistent sealing force at every plate position
• Recessed Chamber Geometry: Cloth surface area and drape geometry matched to the specific recess depth and plate face dimensions — correct fit is essential for uniform cake formation and complete chamber utilisation
• Wide Material Range: Available in PP, PES, nylon, and PTFE woven fabrics — matching chemical and temperature resistance to the specific process fluid in each CGR filter press application
• Reinforced Ears and Drain Holes: Load-bearing ear sections and corner drain holes reinforced to withstand the repeated mechanical stress of filter press closing, pressing, and opening over thousands of cycles
• OEM Plate Database: CGR cloth fabricated to match all standard recessed plate dimensions from Metso, Andritz, JWI, Evoqua, Jingjin, and all other major filter press OEM brands

Technical Specifications

Applications

• Chemical Manufacturing: Pigment, dye, titanium dioxide, and specialty chemical dewatering in CGR recessed-plate presses — the most common filter press type in the chemical industry
• Pharmaceutical: API crystallisation mother-liquor separation and wet cake dewatering in cGMP-compatible CGR filter press systems in pharmaceutical manufacturing
• Mineral Processing: Mining concentrate, calcium carbonate, kaolin, and silica dewatering in CGR presses at mineral processing and beneficiation plants
• Wastewater Treatment: Municipal and industrial sludge dewatering in CGR filter presses — centre-feed design ensures uniform sludge distribution across the full plate face
