Crystal-Clear Liquid Polishing in Horizontal Plate Pressure Filters

Skytech Ultrafab Sparkler Filter Pads are designed for use in horizontal plate (Sparkler-type) pressure filters for final polishing of pharmaceutical syrups, injectables, beverages, edible oils, wines, and chemical solutions. Available in cellulose, cellulose-diatomaceous earth, and synthetic composite constructions in standard grades from coarse to sterile-grade (0.45 µm), they provide exceptional clarity, high dirt-holding capacity, and FDA-compliant material safety.

What Are Sparkler Filter Pads?

Sparkler filters are horizontal plate pressure filter systems in which a stack of circular filter pads is assembled in a pressure vessel. Process liquid is pumped into the vessel and passes horizontally through each pad in sequence, depositing particulates on the pad surfaces and achieving progressive clarification. Sparkler pads combine a depth-filtration layer and a surface-filtration layer to deliver both particle capture and high liquid clarity in a single element.

Features and Benefits

• Multi-Grade Filtration in One Pass: The combination of depth and surface filtration layers captures a broad particle size range in a single pad — coarse particles in the depth layer, fine particles on the surface
• FDA-Compliant Materials: Cellulose and synthetic composite pads manufactured from FDA 21 CFR-compliant materials for direct contact with pharmaceutical liquids, beverages, and food products
• High Clarity Output: Sterile-grade (0.45 µm) pads achieve full bacterial retention — suitable for cold-sterile filtration of beverages and pharmaceutical parenteral products
• High Dirt-Holding Capacity: Thick depth-filtration layer provides high solids loading before pressure differential forces pad replacement — reducing batch interruptions
• All Standard Diameters: Available in 8 inch, 12 inch, 18 inch, and 24 inch diameters to fit all standard Sparkler-type horizontal plate filter systems
• Compatible with Filter Aid: Pads can be used with or without diatomaceous earth or perlite filter aid pre-coat — flexible filtration strategy for varying feed clarity requirements

Technical Specifications

Applications

• Pharmaceutical Syrups and Injectables: Final clarity polishing of oral liquid formulations and small-volume parenteral products — sterile-grade pads achieve bacterial retention for cold sterile filtration
• Beverages: Wine, beer, fruit juice, and soft drink polishing to achieve required turbidity NTU values and bottle-ready clarity without heat treatment
• Edible Oil Clarification: Removal of bleaching earth, soap stock, and fine wax crystals from refined edible oils — delivering water-white colour and brilliant clarity
• Pharmaceutical API Solutions: Clarification of API solution pools prior to crystallisation or spray drying — removes insoluble impurities that would contaminate the crystalline product
• Chemical Solutions: Polishing specialty chemical solutions — electrolytes, reagent chemicals, and pharmaceutical intermediates — to meet specification turbidity limits
