High temperature and chemical resistance up to 260°C. Ideal for waste incineration and chemical processing plants.
Stable performance under continuous high temperatures. Suitable for asphalt mixing, steel, and cement industries.
Fiberglass filter cloth, with its exceptional ultra-high temperature resistance (up to ) and lasting durability,
Excellent resistance to acid, alkali, and moisture. Widely used in coal-fired boilers and thermal power stations.
Stable performance under continuous high temperatures. Suitable for asphalt mixing, steel, and cement industries.
The operating temperature limit for aramid is 204°C (400°F), Aramid filter bags offer good high-temperature resistance and wear resistance.
Polyester filter cloth, Polyester has an operating temperature limit of 135°C (275°F) and comes in both needlefelt and woven media.
Good resistance to hydrolysis and suitable for moist environments like municipal waste treatment.
Expertly customized with various fiber ratios, perfectly adapts to diverse operating temperatures and filtration demands。
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, with its specialized surface treatment, effectively blocks moisture and oily dust, ensuring your dust collection system maintains continuous high efficiency and extended filter bag lifespan in challenging operating conditions.
Our Fiber Blend Series filter cloth, expertly customized with various fiber ratios, perfectly adapts to diverse operating temperatures and filtration demands, helping you achieve highly efficient and energy-saving dust removal goals.
Needle Punching Technology
High-density needle punching ensures uniform fiber distribution, enhancing mechanical strength and dimensional stability. This structure provides excellent air permeability while capturing fine dust efficiently.
Singeing Treatment
Singeing removes surface fuzz and loose fibers, preventing dust re-entrainment and improving cleaning efficiency. It creates a smooth surface ideal for pulse-jet cleaning systems.
Membrane Lamination
A PTFE or ePTFE microporous membrane is laminated onto the fabric surface to achieve ultra-fine filtration. It enables ≤5mg/m³ emission levels, reduces pressure drop, and significantly extends bag life.
Heat Setting
Stabilizes the fabric dimensions after processing, ensuring consistent fit, shrink resistance, and compatibility with bag cages.
Anti-static Finish
Conductive fibers or surface treatments prevent static charge buildup in explosive dust environments (e.g. flour, coal, aluminum powder).
Oil & Water Repellent Finish
Improves resistance to moisture and sticky particles, ideal for humid or oily dust applications like food, biomass, or carbon black.
