Fiberglass Filter Bags
Aokai manufactures woven and needle felt fiberglass filter bags for industrial baghouses operating under high-temperature conditions. Select from fiberglass needle felt, woven fiberglass fabric, and fiberglass composite solutions based on gas temperature, dust properties, chemical conditions, cleaning system, and required service life.
Glassfiber Filter Bags can be constructed using either woven or nonwoven fiberglass fabrics. In addition, fiberglassfilter media can be treated with various options so that they become best suited for various operating conditions,applications, and industries.
- High Temperature Resistance
Can withstand temperatures up to 260 ° C or higher,depending on the specific treatment and construction. - Chemical Resistance
Excellent resistance to acids, alkalis and other corrosivesubstances. - Mechanical Strength
Durable and wear-resistant, extending the service life ofthe filter bag. - Low elongation, dimensional stability
- High Filtration Efficiency
Capable of capturing fine particles and providing effi-cient filtration performance.

Woven Fiberglass Filter Cloth
| Item | Non-woven Fiberglass Filter Bags | Woven Fiberglass Filter Bags |
|---|---|---|
| Material Structure | Fiberglass fibers are mechanically needled into a felt structure, usually with a supporting scrim. | Fiberglass yarns are interlaced in warp and weft to form a stable woven fabric. |
| Typical Temperature Capability | Typically up to 180–240°C, depending on fiber construction and finishing. | Up to 260°C continuous operation in selected constructions. |
| Filtration Performance | Three-dimensional felt structure provides good fine dust capture and dust-holding capacity. | Filtration performance depends on weave density and surface treatment; often selected for stable high-temperature operation. |
| Dimensional Stability | More flexible, with good adaptability to different baghouse designs. | High tensile strength, low elongation, and excellent dimensional stability. |
| Best-Fit Applications | Fine dust collection, pulse-jet baghouses, and medium-to-high-temperature filtration. | High-temperature baghouses requiring low stretch and stable bag dimensions. |

Surface Treatments Available
PTFE Coating
PTFE coating allows dust to remain on the surface of the film and not enter the fibers of the filter material, thereby extending the service life of the filter material.
PTFE Impregnation
The filter material is impregnated in a PTFE solution and then dried to improve the filter material’s resistance to temperature and chemical corrosion.
Graphite coating
Improve the high temperature resistance and oxidation resistance of the filter bag, while enhancing acid and alkali resistance.
Calendering
Calendering makes the filter material surface smooth and uniform in thickness, making it denser, smoother, and easier to clean. It can also reduce the pore size, making it difficult for dust to enter the deep layer of the filter material, thereby increasing the service life of the filter material.
