Fiberglass Filter Media for High-Temperature Filtration

Premium Fiberglass Filter Media Rolls & Filter Bag Solutions

Product Overview

Fiberglass filter media is a proven solution for high-temperature industrial dust filtration, especially in continuous operating conditions above 240 °C.
KABORY supplies premium fiberglass filter media engineered for stable filtration efficiency, low pressure drop, and long service life in demanding industrial environments.

Manufactured from alkali-free E-glass yarns with a consistent 6-micron filament diameter in both warp and weft directions, our fiberglass filter media delivers excellent thermal resistance, structural rigidity, and dimensional stability.
It is widely used in cement kilns, steel plants, carbon black production, incineration systems, and other high-temperature filtration applications.

For processes requiring enhanced dust release and ultra-low emissions, PTFE laminated fiberglass filter media is also available as a high-performance upgrade.

Key Features of Fiberglass Filter Media

High Temperature Resistance (Up to 260 °C Continuous)

Designed for continuous operation at temperatures up to 260 °C, fiberglass filter media remains stable where polymer-based filter media may soften or degrade.

Chemical & Acid Resistance for Aggressive Flue Gases

Naturally resistant to acids, alkalis, and corrosive flue gases, making it suitable for aggressive industrial environments.

Low Airflow Resistance for Energy-Efficient Baghouse Operation

Optimized fabric structure reduces pressure drop, improving baghouse fan efficiency and lowering energy consumption.

High Tensile and Flexural Strength

The woven fiberglass structure provides strong dimensional stability and resistance to vibration and mechanical stress.

Superior Dust Release Properties

Smooth surface finishes and optional PTFE treatments enable efficient dust cake release and extended filter bag life.

Compatibility with Multiple Surface Treatments

Available with a wide range of finishing options to match different dust characteristics and operating conditions.

Why Choose Fiberglass Filter Media for High-Temperature Filtration

Fiberglass filter media is widely used for high-temperature filtration applications where PPS or aramid filter media may not be suitable, particularly under continuous temperatures above 240 °C.

• Higher continuous temperature resistance

• Non-combustible material structure

• Excellent dimensional stability under thermal load

• Reliable performance in oxidizing environments

For cement kilns, steel furnaces, carbon black reactors, and incineration systems, fiberglass filter media remains a widely adopted industry standard.

PTFE Laminated Fiberglass Filter Media

 

PTFE laminated fiberglass filter media is designed for applications with strict emission limits, sticky dust, or demanding cleaning conditions.

PTFE Laminated Fiberglass Filter Media Performance：

• Ultra-low particle emissions

• Excellent dust cake release

• Reduced filter bag blinding

• Lower and more stable pressure drop over time

PTFE laminated fiberglass filter media is especially suitable for modern baghouse systems where environmental compliance and long-term operational stability are critical.

After-Treatment & Finishing Options

To meet diverse industrial dust collection requirements, our fiberglass filter media can be customized with the following finishing processes:

• Singeing & Calendering – Improves surface smoothness and fabric uniformity

• PTFE Coating – Enhances water repellency, chemical resistance, and anti-adhesion

  

• PTFE Lamination – Enables ultra-low emissions and superior dust release

• Acid-Resistance Treatment – Protects against corrosive flue gases

• Corrosion-Resistance Treatment – Ensures long-term media stability in aggressive environments

• Anti-Adhesion Finish – Minimizes dust retention and facilitates cleaning

These finishing options allow fiberglass filter media to be optimized for different dust characteristics, operating temperatures, and cleaning systems.

Quality Control from Raw Material to Finished Media

Our quality control starts at the raw material level, using high-consistency, alkali-free E-glass yarns specifically selected for high-temperature fiberglass filter media applications.
All warp yarns undergo strict warping control before weaving, followed by a tower-type finishing process to enhance dimensional stability, surface uniformity, and batch-to-batch consistency under high-temperature operating conditions.

Note: Final media selection should consider temperature profile, dust characteristics, and cleaning intensity.

To achieve long service life in high-temperature baghouse filtration, proper system design and operating conditions are essential.

While fiberglass filter media provides excellent high-temperature performance, proper system design and operation are essential to maximize service life:

• Fiberglass fibers have limited flex resistance compared with needle-punched felts

• Excessive pulse-jet cleaning intensity should be avoided

• Proper filter cage design and bag support are critical

• PTFE coating or lamination is strongly recommended for demanding applications

When correctly selected and operated, fiberglass filter media delivers stable, long-term filtration performance even under extreme thermal conditions.
