Adding an ePTFE membrane to an aramid filter bag allows the membrane to act as the filter cake. Dust stays on the surface of the membrane and does not get entrained into the fibers of the filter bag, which lengthens the life of your filter bag. It also reduces wear and tear, lower maintenance costs, and energy costs due to easy dust cake release during the cleaning cycle.
PPS Filter Cloth
PPS filter cloth (Polyphenylene Sulfide filter fabric) is widely used in high-temperature industrial dust filtration systems. It offers excellent resistance to high temperature, acid gases, and chemical corrosion,Our PPS filter cloth provides stable filtration efficiency and long service life under harsh operating conditions.
- Excellent High Temperature Resistance：Continuous operating temperature up to 160°C, instant temperature up to 190°C.
- Outstanding Chemical Resistance：PPS fiber performs well under acidic gas environments, especially suitable for SO₂ / NOx containing flue gas.
- Excellent Hydrolysis Resistance：Compared with many high-temperature fibers, PPS shows strong resistance to hydrolysis and moisture environments.
- Long Service Life：With optimized fiber structure and finishing treatment, PPS filter cloth provides stable operation and longer replacement cycles.
