FMS filter bags are developed for processes where heat, abrasion, and corrosive gas chemistry converge—conditions that rapidly destroy conventional felts. By combining glass fiber with high-temperature resistant felts such as P84, FMS media forms a reinforced structure capable of withstanding:
- continuous heat around 200–260 °C
- peak temperatures approaching 280–300 °C
- abrasive dust from kilns, smelters, and furnaces
- corrosive vapors such as acids, alkalis, and industrial solvents
Compared with basic glass-fiber felt, FMS offers superior abrasion resistance, better pulse-cleaning performance, and significantly longer lifetime in fluctuating operating conditions. It is particularly effective in high dust-loading applications and environments where temperature, chemistry, and particulate characteristics change unpredictably throughout the day.
Typical operating advantages include:
- excellent thermal stability under repeated cycling
- strong chemical tolerance
- stable permeability and airflow
- reliable structure under high A/C ratio filters
- prolonged service life in cement, steel, waste-to-energy, and smelting sectors
