Filter Cloth
Filter Cloth from Aokai Environtec is the essential filtration material for industrial dust collector bags. It captures fine particulates efficiently while maintaining low pressure drop and stable system performance.
Aokai’s advanced needle-punching technology creates a dense, uniform structure that forms a stable dust cake quickly — delivering high filtration efficiency (>99.9%), excellent pulse-cleaning release, and 20–50% longer bag life.
Aramid(Nomex) Filter Cloth
Aramid filter cloth engineered for reliable high-temperature filtration with excellent thermal stability up to 240°C.
PTFE(Teflon) Filter Cloth
High temperature and chemical resistance up to 260°C. Ideal for waste incineration and chemical processing plants.
PPS Filter Cloth
Excellent resistance to acid, alkali, and moisture. Widely used in coal-fired boilers and thermal power stations.
Polymide (P84) Filter Cloth
Resistant to 280℃ high temperature with high filtration precision, it is specially designed for dust removal in waste incineration and cement kiln tail.
FiberGlass Filter Cloth
High-temperature Fiberglass Filter Cloth for industrial baghouse systems — stable filtration up to 260°C, low pressure drop, and long service life.
FMS Filter Cloth
FMS Filter Cloth handle 260°C+ with great abrasion and corrosion resistance—longer life, less hassle and cost in cement and steel plants.
Polyester Filter Cloth
Polyester Filter Cloth is a cost-effective and widely used filter media for standard temperature applications, with a continuous operating temperature up to 130°C(266°F) .
Acrylic Filter Cloth
Acrylic Filter Cloth is designed for industrial dust collection in humid and acidic environments, providing excellent hydrolysis resistance and stable long-term performance to reduce unexpected bag failure and downtime.
Anti-static Filter Cloth
Anti-static filter cloth safely dissipates static electricity, completely eliminating the risk of dust explosions and providing a more secure and stable dust removal solution for your industrial operations.
Water and oil repellent Filter Cloth
Water and oil repellent filter cloth is a high-efficiency filter material with excellent waterproof and oil-proof properties, effectively preventing paste and clogging.
PTFE+PPS Filter Cloth
PTFE+PPS Filter Cloth offers excellent chemical resistance and high-temperature durability for demanding dust collection
Needle Felt with PTFE Membrane
High-efficiency dust filter material with PTFE membrane laminated on needle felt, offering ultra-fine filtration, easy cleaning and long service life.
Polyester + Acrylic Blend Filter Cloth
This blend improves hydrolysis resistance compared to pure polyester, while maintaining cost efficiency.
Glass Fiber + Aramid Blend Filter Cloth
This blend improves hydrolysis resistance compared to pure polyester, while maintaining cost efficiency.
PPS + GlassFiber Blend Filter Cloth
Glass fiber improves tensile strength and dimensional stability, while PPS provides chemical resistance.
PTFE+PPS Filter Cloth
Expertly customized with various fiber ratios, perfectly adapts to diverse operating temperatures and filtration demands。
Flame-Retardant Filter Cloth
Flame-retardant filter cloth is a specialized fabric used in dust collection filter bags for high-risk environments (e.g., welding, metal grinding, chemical plants).
PTFE + P84 Needle Felt Filter Cloth
High-performance blended needle felt filter fabric with excellent heat resistance, acid-alkali resistance and high filtration efficiency.
Choose the Right Filter Media for Your Dust Collection System
Different industrial processes require different filter media depending on temperature, chemical exposure, and dust characteristics.
The comparison below shows the temperature limits and chemical resistance of the most commonly used filter materials to help you quickly identify the suitable option for your baghouse system.
