Yuanchen makes PPS filter bags for dust collection from hot flue gases
Yuanchen of Hefei makes PPS filter bags for baghouses running at 160 to 190 °C with chemically aggressive flue gases, for example in power plants, cement works, waste incineration and the steel industry.
Filter bags for hot and aggressive flue gases
Anhui Yuanchen Environmental Protection Science & Technology was founded in 2005 and is based in Hefei, Anhui province. The company makes filter fabrics, dust filter bags, stainless steel bag cages and SCR honeycomb catalysts for industrial flue gas cleaning. In May 2026 it was on the exhibitor list of IFAT in Munich, Germany.
PPS filter bags
For baghouses that operate at high temperatures and with chemically aggressive exhaust gases, Yuanchen offers filter bags made of polyphenylene sulfide (PPS). According to the manufacturer they are designed for continuous operation between 160 and 190 °C and can withstand higher temperatures for short periods. PPS fibres resist many acids, alkalis and corrosive gases, so they are used where polyester or acrylic filter media are no longer suitable. The company names power plants and coal fired boilers, cement kilns and clinker coolers, municipal and hazardous waste incineration as well as metallurgy and the steel industry as fields of use. The design is adapted to the operating temperature and the flue gas composition.
Further filter media
Besides PPS, Yuanchen supplies filter bags and filter cloth made of PTFE, polyester, acrylic, Nomex, P84 polyamide and fiberglass with PTFE membrane, plus flame retardant polyester bags and PPS/PTFE composite bags. The website states an annual capacity of 1.26 million filter bags and is also available in German.
