Fiberglass filter cloth

Filmedia® fiberglass filter cloth is widely used for industrial dust collection because of its high covering capacity , good air permeability and high filtration efficiency. Woven fiberglass is great fabric for RABH filter bag, heat-resistance.
Capacity:2000 m² per day.
FAW: 200-850 gsm and other customized weight.
Weave: plain, twill, satin.

Optional Choice: Pleated Filter Bag (Star Bag)

The main advantages and features:

1. To increase system filtration capacity by 50-150% as needed without major changes to the dust collectors ;

2. System cleaning efficiency markedly increased with the effective increase of bag to bag distance;

3. Bag life extended due to significant reduction of fatigue damage to the bags due to bag to cage impact.

Fiberglass filter cloth has high covering capacity and good air permeability,thus providing higher filtration efficiency,lower filtration resistance.


Widely used in industry of carbon black, steel and non-ferrous metal processing, cement industry, chemical plant, power plant, etc, for dust collection, air filtration.


According to the weaving method:
1. Flat Fiberglass Filter Cloth
2.Textured Fiberglass Filter Cloth

According to the yarn type:
1. Continuous yarn fiberglass filter cloth
2. Bulk yarns fiberglass filter cloth

Flat Fiberglass Filter Cloth compared with Textured Fiberglass Filter Cloth

Flat fiberglass’s wearability, fastness is higher than the textured. While its elasticity, tenderness, glossiness is lower than the textured. Despite the differences, they share the same price. 平纹和斜纹对比图

Continuous yarn filter cloth compared with bulk yarn fiberglass filter cloth

Bulk yarn fiberglass filter cloth is weaved by fluffy yarn, which is more permeable than the continuous yarn. Besides, it improves the de-dust efficiency which can up to more than 99.5% and the filtration speed can up to 0.6-0.8m/min. The price of bulk yarn fiberglass is higher than continuous yarn fiberglass filter cloth.
