RF-SP Series — Sparkler Filter Cloths
Precision filter pads and cloths for horizontal plate (Sparkler-type) pressure filters. Engineered for polishing, clarification, and pre-coat filtration in food, pharma, and chemical applications.
Series Overview
Sparkler-type horizontal plate filters use stacked circular filter plates inside a closed pressure vessel. The RF-SP Series provides precision-cut filter cloths that cover these plates, delivering consistent particle retention and filtrate clarity. The horizontal plate design is particularly effective for polishing applications where pre-coat media (diatomaceous earth, perlite, activated carbon) are used.
Every RF-SP cloth is cut to your exact plate diameter and centre-hole dimension. We match material, weave, and pore size to your specific liquid and retention target.
Fine Retention
Down to 1 µm
Pre-Coat Support
DE, perlite, carbon
Precision Cut
Exact plate fit
Crystal Clear
Polishing-grade filtrate
Key Features
Uniform Pre-Coat Build-Up
Smooth monofilament surfaces provide a consistent base for pre-coat media deposition. Even cake thickness across the entire plate.
Consistent Retention
Controlled pore geometry delivers batch-to-batch reproducibility. No turbidity spikes, no bypass — even after multiple cleaning cycles.
Chemical Compatibility
Full range of polymer materials to match your process chemistry: PP for acids/alkalis, PET for general use, PA for specific applications.
Easy Cake Discharge
Clean discharge of spent filter aid during blow-down. Smooth surfaces prevent residue accumulation and enable fast plate turnaround.
Exact Plate Dimensions
Precision-cut to your plate diameter and centre-hole size. Clean edges, proper bolt-hole alignment, wrinkle-free fit.
Food & Pharma Grade
Materials compliant with FDA 21 CFR and EU (EC) 1935/2004 for food-contact and pharmaceutical polishing applications.
