PTFE Laminated Polyester Filter Cartridge
Surface-filtration cartridge combining a polyester felt substrate with an expanded PTFE membrane for fine dust and easy cleaning.
Filter Cartridge Series
PTFE Laminated Polyester Filter Cartridge
PTFE laminated polyester filter cartridge uses high-density polyester needle felt as the substrate and a hot-pressed microporous expanded PTFE membrane as the filtration surface. Dust remains on the membrane instead of penetrating the fiber layer, reducing blockage and making pulse cleaning easier while the polyester base provides strength and toughness.
Base fabricHigh-density polyester needle felt
Surface membraneExpanded microporous PTFE membrane
Continuous working temperature≤160℃
Filtration rating0.1 μm
Filtration velocity0.6–1.2 m/min
Initial pressure drop250–500 Pa
