Recessed Bottom-Feed Non-Gasketed Filter Press Cloth

Skytech Ultrafab RBN Filter Press Cloth is engineered for Recessed-chamber, Bottom-feed, Non-gasketed filter presses used in chemical, pigment, dye, and mineral processing applications where slurry is introduced through a bottom or corner feed port rather than a centre hole. Each RBN cloth is precision-fabricated with the feed neck at the correct bottom or corner position, reinforced ear sections, and open-face construction that promotes rapid filtrate drainage and clean cake release at every filter press cycle.

What Is RBN Filter Press Cloth?

RBN stands for Recessed-chamber, Bottom-feed (or corner-feed), Non-gasketed — describing the three defining construction features of this filter press cloth variant. The bottom-feed design routes slurry into the filter chamber from the bottom or corner of the plate rather than through a centre hole — beneficial for thick, viscous, or fast-settling slurries where a centre feed would cause uneven chamber filling. Non-gasketed construction means the cloth relies on the plate face clamping force alone for sealing, without a separate gasket component.

Features and Benefits

• Bottom or Corner Feed Neck: Feed neck positioned at the bottom or corner of the cloth at the exact location of the plate feed port — ensures correct slurry entry point for uniform chamber filling in bottom-feed press configurations
• Non-Gasketed Open Face: Cloth edge finished without integrated gasket — relies on plate face clamping load for sealing, simplifying cloth installation and reducing per-cloth cost versus gasketed alternatives
• Recessed Chamber Fit: Cloth surface geometry matched to the specific recess dimensions of the plate — correct drape and surface area ensures full utilisation of the filter chamber volume
• Full Material Range: Available in PP, PES, nylon, and cotton woven fabrics covering acidic, alkaline, and neutral process fluid chemistry from ambient to 135°C
• Reinforced High-Stress Points: Ear sections, feed neck, and corner drain holes double-stitched and reinforced to withstand the repetitive mechanical loading of filter press open-close cycles
• Custom Neck Position: Feed neck fabricated at any position on the cloth perimeter or within the cloth body — accommodates all bottom-feed, side-feed, and corner-feed plate configurations

Technical Specifications

Applications

• Chemical Industry: Pigment, dye, and specialty chemical slurry dewatering in bottom-feed recessed-chamber filter presses — bottom-feed design handles thick and fast-settling chemical slurries
• Mineral Processing: Mining slurry and industrial mineral dewatering where bottom-feed press configuration provides better chamber filling with dense, heavy mineral concentrate
• Wastewater Sludge: Industrial and municipal sludge dewatering in bottom-feed recessed presses — bottom entry promotes even sludge distribution for uniform cake thickness
• Sugar and Starch: Sugar juice clarification and corn starch slurry pressing in filter presses equipped with bottom-feed plate configurations
• Ceramics and Clay: Ceramic slip and kaolin clay dewatering in filter presses — bottom feed handles the thick, sticky nature of ceramic slurries that would block centre-feed arrangements

Why Choose Skytech Ultrafab for RBN Filter Press Cloth?

• Any Feed Position: Bottom, corner, or side feed neck positions all fabricated from the same specification capability — no standard position limitation when the plate requires a non-centre feed location
• Simplified Installation: Non-gasketed construction reduces installation steps versus gasketed cloths — faster press reloading during cloth change campaigns reduces filter press downtime
• OEM Plate Matching: RBN cloths fabricated to the exact dimensions of all major filter press OEM recessed plates in bottom and corner-feed configurations — guaranteed fit from the first installation
• Full Material Range: PP, PES, nylon, and cotton cover all process chemistry requirements for bottom-feed RBN applications — same specification flexibility as centre-feed cloths
• Fast Fabrication: Standard plate size RBN cloths produced in 7–10 working days; non-standard positions and dimensions in 10–14 working days from plate drawing confirmation
