FMS Filter Bag
Darko’s FMS filter bags combine PTFE fibers with ultra-fine fiberglass in a needle-punched composite structure, delivering both fiberglass’ heat resistance and PTFE’s chemical stability. Ideal for cement kilns, waste incinerators, and steel sintering plants, these bags operate continuously at 260°C (500°F) with peak resistance to 300°C (572°F).
- Superior Chemical Resistance
- Exceptional High-Temperature Performance
- 2X Longer Service Life
- Self-Cleaning Surface
- Cost-Effective Solution

Why Choose FMS Filter Bags? The Ultimate Balance of Performance & Value
For industrial operations demanding reliable filtration under extreme conditions, FMS filter bags deliver the perfect synergy of durability, efficiency, and cost-effectiveness. Here’s why global plants trust FMS technology:
✅ Unbeatable Composite Performance
• PTFE + Fiberglass Hybrid Matrix – Combines PTFE’s chemical resistance with fiberglass’ structural integrity, outperforming single-material bags in high-SOx/NOx flue gas
• 260°C Continuous / 300°C Peak – Handles cement kiln bypass and incinerator exhaust with ease
• 2X Longer Lifespan vs. standard fiberglass bags in corrosive, high-humidity environments
✅ Smart Cost Savings
• 30% Lower Upfront Cost than pure PTFE bags
• 15% Reduced Energy Use thanks to optimized airflow (15-20 CFM/ft²)
• Minimal Maintenance – Resists blinding and maintains stable pressure drop
✅ Certified for Critical Applications
✔ Waste Incineration – Complies with EU 2015/1189 for dioxin control
✔ Coal Power – Handles high-sulfur flue gas (SOx >2000ppm)
✔ Steel & Cement – Meets GB/T 6719 ultra-low emission limits
✅ Future-Proof Customization
• PTFE Membrane Lamination for PM0.3 capture
• Anti-Static Variants (ATEX-certified)
• FDA-Compliant options for food/pharma
FMS bags combine PTFE’s chemical resistance with fiberglass’ strength, delivering:
✔ 2X longer lifespan in high-SOx/NOx flue gas
✔ 30% lower pressure drop for energy savings
✔ pH 1-12 chemical resistance (vs. fiberglass’ pH 4-9 limit)
While P84 excels in continuous 260°C+ dry gases, FMS bags:
✔ Perform best at 200-260°C (ideal for cement kiln bypass)
✔ Outlast P84 in humid, acidic conditions (e.g., waste incineration)
✔ Cost 20-30% less than P84 for comparable applications
Yes! Their PTFE-fiberglass blend resists:
✔ SOx corrosion (coal combustion byproducts)
✔ Fly ash abrasion (500,000+ pulse cycles)
✔ Moisture (<0.5% water absorption)
For PM2.5 control, add PTFE membrane lamination.
Typical service life:
• 24-36 months in cement kilns
• 18-24 months in waste incinerators
Signs for replacement:
