Fiberglass Filter bag

Product Overview

The fiberglass filter bag is a high-performance filtration solution designed to withstand high temperatures. It features excellent structure and efficiency, making it an ideal choice for various industrial applications. With high porosity and low filtration resistance to gas, this filter bag operates effectively at high speeds, providing superior filtration.

Key Benefits

High Tensile Strength: The fiberglass filter bag offers tremendous support in complex industrial processes, ensuring durability and reliability.

Temperature Resistance: Designed to handle operating temperatures between 200°C and 300°C, it can even tolerate up to 400°C while maintaining excellent filtration efficiency.

Corrosion Resistance: The fiberglass material exhibits strong chemical stability and resists damage from acids, alkalis, and organic solvents.

High Filtration Efficiency: Its fine fibers and small pore sizes ensure that even tiny particles are effectively filtered out.

Low Filtration Resistance: This filter bag allows for good airflow, ensuring efficient filtration without compromising ventilation.

What is Fiberglass?

Fiberglass is an inorganic fiber primarily composed of SiO2. It is produced by melting glass frit at temperatures between 1300°C and 1600°C, drawing filaments from the molten state, and rapidly quenching them. There are two main types of fiberglass filter materials:

C Glass: Medium-alkali glass or soda-lime silicate glass.

E Glass: Alkali-free glass or aluminoborosilicate glass.

Advantages of Fiberglass

High Temperature Resistance: Excellent performance under high temperatures.

Dimensional Stability: Maintains shape and strength over time.

High Tensile Strength: Capable of withstanding significant stress.

Chemical Resistance: Stable against most media, except hydrofluoric acid and strong alkalis.

Comparison: PTFE vs. Fiberglass Filter Bags

When choosing between PTFE and fiberglass filter bags, consider the following:

Filtration Efficiency

PTFE Filter Bags: Achieve over 99.99% effectiveness in filtering fine particulates and harmful gases.

Fiberglass Filter Bags: Generally achieve around 90% filtration efficiency.

Corrosion Resistance

PTFE Filter Bags: Offer excellent resistance in harsh environments.

Fiberglass Filter Bags: Less resistant to strong acids and bases.

Temperature Tolerance

PTFE Filter Bags: Function effectively from -196°C to 260°C.

Fiberglass Filter Bags: Operate within -60°C to 250°C.

Lifespan

PTFE Filter Bags: Last 3-5 years due to higher resistance.

Fiberglass Filter Bags: Typically last 1-2 years.

Price

PTFE Filter Bags: More expensive, costing 2-3 times more than fiberglass options.

Fiberglass Filter Bags: More affordable, making them suitable for cost-sensitive applications.

Conclusion

Both PTFE and fiberglass filter bags have unique strengths and weaknesses. Choose based on your specific needs. For high filtration efficiency, corrosion resistance, and temperature tolerance, PTFE filter bags are ideal. If cost is your primary concern, fiberglass filter bags offer a reliable alternative.
