Sparkler Filter Pads
Overview
Sparkler filter pads are specialized depth filtration media used in horizontal plate filters, particularly in Sparkler®-type filter presses. These pads are essential for polishing, clarifying, and removing fine suspended particles from liquids in pharmaceutical, food, cosmetic, chemical, and beverage industries.
At Filtech Textiles, we produce high-performance filter pads compatible with all sparkler filter systems, engineered for high dirt-holding capacity, precise filtration, and long service life.

Types of Filter Media Used in Sparkler Filter Pads
| Material | Media Type | Micron Rating | Advantages | Limitations |
|---|---|---|---|---|
| Cellulose Fiber | Non-Woven (Depth) | 1 – 50 µm | Excellent depth filtration, biodegradable, cost-effective | Not suitable for strong solvents |
| Polypropylene | Woven / Non-Woven | 1 – 200 µm | Chemically inert, good solvent & acid resistance | Limited temp resistance (~90°C) |
| Polyester (PET) | Woven / Non-Woven | 1 – 10 µm | Durable, abrasion-resistant, withstands high temps (~150°C) | Moderate acid resistance |
| Nylon Monofilament | Woven (Surface) | 10 – 150 µm | Smooth surface, easily washable, good mechanical strength | Limited chemical compatibility |
| Glass Fiber | Non-Woven (Depth) | 1 – 5 µm | High-temp stable, fine particulate retention | Brittle, limited reusability |
