Fabric Filter Bags

Fabric filter bags are dust collection elements in industrial air systems. In plants handling cement, metal products, pharmaceuticals or power generation, you will find these filter elements (usually cylindrical or pleated) based on textile processes.

What is their secret? Materials such as polyester fibers for everyday use, glass fibers for high temperatures (we're talking 260°C high) or PTFE coatings when chemicals are involved. That's where fabric filter bags come in - capturing everything from powdered medications to gritty coal dust without clogging.

Focuses on trapping particles, automated cleaning, and dust removal:

• Filtering: Dusty gas flows into the filter. Large particles get stuck on the outside of fabric filter bags. Clean air moves through the surface into a clean-air chamber.
• Cleaning: At set times, bursts of compressed air or shaking knocks the collected dust layer off the bags. The system keeps running without stopping.
• Disposal: The loosened dust drops into a hopper below. It's then moved (by air or manually) for disposal or reuse.

 

Key features

 

High-Efficiency Filtration

Capture submicron particles (≤1μm) with filtration efficiency up to 99.9%, ensuring compliance with strict international emission standards.

 

Diverse Material Options for Specific Conditions

Customizable fabrics: PTFE (chemical resistance, 260°C), Nomex (heat resistance, 200°C), PPS (acid/alkali resistance), and Polyester (cost-effective for moderate temperatures). Optional coatings (e.g., ePTFE membrane).

 

Robust Structural Design

Reinforced seams (e.g., triple-stitched or heat-sealed) to prevent bag failure under high-pressure pulse-jet cleaning.
Anti-static and abrasion-resistant treatments for hazardous environments.

 

Custom Engineering Support

Surface Treatments: Anti‑static, water/oil repellency, PTFE coating, silicone impregnation.
Accessory Integration: Support cages, flanges, gaskets, venturis, and quick‑disconnect fittings.

 

Applications

• Cement & Lime Plants: Raw mill, kiln, and clinker cooler dust control.
• Power Generation: Coal-fired boilers and biomass plants for fly ash removal.
• Metal Processing: Steel pickling, foundries, and smelting to capture metallic dust.
• Pharmaceuticals & Food: Non-toxic fine powders requiring high-purity air.
• Chemical & Plastics: Corrosive or thermally sensitive dust streams.
