We Craft Every Filter Bag with Care
Our filter bags 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.
Engineered for Extreme Heat & Corrosive Environments
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.

Non-woven Fiberglass Filter Cloth


Woven Fiberglass Filter Cloth
| Item | Non-woven Fiberglass Filter Bags | Woven Fiberglass Filter Bags |
|---|---|---|
| Manufacturing process | Glass fibers are combined physically or chemically using non-woven processes such as needle punching. | Glass fiber yarn is woven into cloth. The yarn is arranged in a certain warp and weft to form a regular fabric structure. |
| High temperature resistance | Higher, slightly lower than woven type. | Extremely high, can withstand high temperature environment, suitable for use under high temperature conditions. |
| Mechanical strength | Low, but better softness and adaptability. | Strong, wear-resistant, suitable for harsh working environment. |
| Filtration efficiency | High, good air permeability, suitable for capturing fine particles. | High, but relatively poor air permeability. |
| Applicable environment | Medium temperature, low corrosion and fine dust particles environment. | High temperature, high corrosion and high wear environment. |

Fiberglass Woven Fabric Filter Bags


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.
