Providing high-efficiency filtration solutions for multiple industries.
P84 needled felt filter bags
P84 (polyimide) filter bags offer a continuous 240°C with superior dust capture thanks to the unique trilobal fiber shape — a smart middle ground between PPS and PTFE, best suited for dry, high-temperature flue gas; avoid high-humidity applications where hydrolysis becomes a risk.Explore our complete range of industrial filtration products, including PPS, PTFE, fiberglass and aramid filter bags.
