Surface Treatments
To optimize filtration performance and extend service life, FMS fiberglass filter bags are available with specialized surface treatments:
PTFE Coating: Enables surface filtration, reduces cleaning frequency, and prevents dust penetration into fiber interior
Silicone Oil Impregnation: Enhances flexibility and reduces fiber brittleness and breakage risk
Applications
Ideal for high-temperature flue gas purification systems across multiple industries including:
Metallurgy
Cement Production
Chemical Processing
Waste Incineration
Installation & Usage Notes
These filter bags are designed for use with rigid filter cages and are best suited for applications with stable gas flow conditions. Their classic design has established them as a preferred choice in industrial high-temperature dust removal systems.
Note: Due to moderate flexibility and wear resistance characteristics, these filter bags are not recommended for high-velocity airflow or strong gas flow erosion conditions.
