As a dust filter cloth manufacturer, we provide fully customizable fabrics to meet specific application needs. Options include:
We Craft Every Filter Cloth with Care
Our filter cloth are designed based on actual site conditions, not generic catalog assumptions. We help you select the right media to balance filtration efficiency, pressure drop, and service life.
Needle-Punched Felt Filter Cloth
Needle Punched Felt Filter Media 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.
With customizable treatments (singed, calendered, PTFE membrane, antistatic, water/oil repellent, etc.), Aokai ensures low emissions, reduced energy use, equipment protection, and reliable compliance with strict regulations.
PTFE Filter Fabric
High temperature and chemical resistance up to 260°C. Ideal for waste incineration and chemical processing plants.
PPS Needle Felt
Excellent resistance to acid, alkali, and moisture. Widely used in coal-fired boilers and thermal power stations.
FiberGlass Filter Fabric
Fiberglass filter cloth, with its exceptional ultra-high temperature resistance (up to ) and lasting durability,
Nomex Fabric
The operating temperature limit for aramid is 204°C (400°F), Aramid filter bags offer good high-temperature resistance and wear resistance.
Aramid Needle Felt
It resists 240℃ high temperature and is flame-retardant, serving as an efficient filter material for dust removal in metallurgy and chemical industries.

Polymide (P84) Filter Fabric
Resistant to 280℃ high temperature with high filtration precision, it is specially designed for dust removal in waste incineration and cement kiln tail.
Polyester needle felt
Polyester filter cloth, Polyester has an operating temperature limit of 135°C (275°F) and comes in both needlefelt and woven media.
Acrylic non-woven filter cloth
Good resistance to hydrolysis and suitable for moist environments like municipal waste treatment.

Fiber Blend Series
Expertly customized with various fiber ratios, perfectly adapts to diverse operating temperatures and filtration demands。
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
Processed by special technology, water and oil repellent filter cloth has excellent water and oil repellent properties. It can effectively prevent dust adhesion and filter cloth clogging, adapt to dust removal scenarios of oily and humid flue gas, and improve both dust removal efficiency and service life.

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).
Applications
Aokai provide custom felt filter cloth solutions for abrasive, corrosive, high-temperature, and explosive dust filtration.
Related Products
We also provide various high-quality filter cages, filter bags, and other accessories to offer you a one-stop dust removal solution.
Our focus is not just supplying filter bags, but reducing your total filtration cost over time.
