Key Advantages
- ✓Excellent High Temperature Resistance: Perfect choice for continuous high-temperature flue gas filtration systems.
- ✓High Mechanical Strength: Superior abrasion and flex resistance compared to conventional fiberglass felt.
- ✓Good Chemical Resistance: Highly stable even under acidic and alkaline gas conditions.
- ✓High Filtration Efficiency: Reaches up to 99.99% efficiency for fine particulate filtration.
- ✓Low Operating Resistance: Advanced surface filtration structure improves airflow and dust release performance.
- ✓Excellent Dust Cleaning: Premium PTFE treatment effectively reduces dust adhesion and pressure buildup.
- ✓Extended Service Life: Offers a typical operating life of 2–5 years under complex working conditions.
⚠️ Technical Application Notes & Limitations
- • Sensitive to strong oxidizing conditions (High O₂ and NO₂ concentrations may accelerate fiber aging).
- • Higher initial investment cost compared to standard fiberglass filter media.
- • Performance heavily relies on surface treatment quality (PTFE membrane/coating integrity).
- • Material evaluation is highly required under extreme Hydrofluoric Acid or strong alkaline steam.
Typical Industrial Applications
FMS needle felt is widely engineered for industrial bag filters, standing as an extremely effective solution to capture fine particles in harsh, demanding environments. Capable of handling high filtration face velocity, it yields substantial economic benefits by significantly lowering system resistance. The service life of FMS filter bags can reliably extend to more than 2 years, drastically cutting down down-time and maintenance costs in the following fields:
01. Steel Industry: Blast furnace gas, electric furnace, converter, sintering workshop.
02. Metallurgy: Smelting facilities for copper, zinc, and aluminum.
03. Carbon Black: Production and manufacturing filtration processes.
04. Cement Plants: Kilns, mills, vertical windows, and packaging workshops.
05. Ferroalloy: Smelting and production dust collection.
06. Carbide Stoves: High-temperature gas filtration.
07. Power Plants: Coal-fired boiler emission systems.
08. Waste Incinerators: Clean waste, industrial waste, and medical waste facilities.
09. Asphalt Mixing: Industrial asphalt production workshops.
10. Other Applications: Pesticides, dyes, lime kilns, titanium dioxide, and asbestos.
