Material:

Glass fiber filter cloth is made of the fiberglass yarn with special treatment like graphite, silicon, PTFE dipping, Acid repellent treatment and other chemical treatments. It is an ideal high temperature resist filter cloth. The fiberglass filter bags are widely used in industrial dust clean area, bag houses, air pollution and valuable dust recycling applications etc.

Performance:

1. Good heat resistance, suitable for long-term use under a temperature below 280 deg.

2. Good dust peeling performance, low power consumption for ash removal.

3. The size of the fiberglass filter bags is much more stable, no fiber shrinkage under the high temperature.

4. Good chemical resistance: In hydrolysis, strong acid and strong alkaline environment it is more stable than other filter medium.

5. The fiberglass filter fabric does not absorb moisture in humid conditions.

6. The filtering efficiency of the fiberglass filter bag can be over 99.5% . It can catch the dust particles and contaminants below the PM2.5. It can reach air release of 20mg and more.

7. High strength of the fiberglass filter cloth which is around 3000N/5*20cm.

Specifications

1. Main products: two categories of medium alkaline and alkaline free glass fiber filter cloth(bag).

2. various types:heat treatment,silicone oil, graphite.

3. various thickness:0.3-0.5mm

4. various diameters

Application

The cement industry

Cement kiln character;

Cement raw material in the decomposition oven is not completely decomposed into caco3 dust.

Together with caco3 dust during the decomposition of the CaO is produced.

For burning pulverized coal produced in the combustion process so2 nox co co2 and other gases.

Kiln temperature exhaust gas from the cyclone out of more than 320 degrees drying gas.

Dust concentration of dust particle size less than 10um accounted for more than 90%.

Sometimes co-content according to each of the combustion fluctuate

FAQ

Q
What is woven glass fiber dust collection fabric? What are its main characteristics?
A
Woven glass fiber dust collection fabric is a filtration material made from glass fiber yarns through weaving techniques such as plain weave, twill weave, or satin weave. Its core characteristics include exceptional high-temperature resistance (continuous operating temperature up to 260°C, withstanding instantaneous temperatures up to 280°C), excellent dimensional stability (no shrinkage within standard temperature ranges), good chemical corrosion resistance, and high filtration efficiency (achieving over 99.5%).
Q
How does woven glass fiber filter fabric differ from nonwoven (needle-punched felt) filter materials?
A
The primary distinction lies in structure and filtration mechanism. Woven fabric features a two-dimensional structure formed by interlaced yarns, relying on interstitial pores for filtration—closer to surface filtration. It offers dimensional stability, relatively lower dust-holding capacity, but facilitates easy cleaning. Nonwoven needle-punched felt, however, exhibits a three-dimensional structure with interlocked fibers, primarily employing depth filtration and offering high dust-holding capacity.
Q
What is the grammage (GSM) range for your products? How do I select the appropriate GSM?
A
Our woven glass fiber filter media covers a GSM range from 450 to 800, with common specifications including 500 GSM, 550 GSM, and 750 GSM. Generally, higher GSM indicates thicker media with enhanced mechanical strength and abrasion resistance. Our technical team can recommend the most suitable GSM based on your specific requirements (e.g., filtration precision, durability).
Q
What is the specific temperature resistance of woven glass fiber filter media?
A
This filter media can withstand continuous operating temperatures up to 260°C (516°F) and momentary temperatures up to 280°C (536°F). Some products even tolerate momentary temperatures as high as 295°C (567°F). This makes it suitable for handling high-temperature flue gases from most industrial furnaces.
Q
What types of chemical dust or fumes is it suitable for handling?
A
Woven glass fiber filter media exhibits excellent chemical corrosion resistance. It remains stable against most chemical media, except for hydrofluoric acid, strong acids, and strong alkalis. Consequently, it is widely used in industries with complex chemical environments, such as cement production, steelmaking, coking, chemical processing, and non-ferrous metal smelting.
