Composite Fiberglass Filter Paper Suppliers and Factory in China
Composite Fiberglass Filter Paper is a high-performance filtration medium engineered from ultra-fine glass fibers using a sophisticated wet process. By integrating ultra-fine glass fiber paper with a durable non-woven fabric layer, this composite material provides superior protection for the core filtration medium, available in either single-sided or double-sided composite configurations to meet diverse industrial requirements.
Designed for the most demanding environments, this material is characterized by its exceptional dirt-holding capacity, low airflow resistance, and high mechanical strength. It delivers stable and reliable performance across critical applications, including air compressors, automotive engines, fuel turbines, nuclear filtration, and natural gas engineering, ensuring purity and system longevity in heavy industry, petroleum, aviation, and chemical sectors.

| Performance Metric | Standard Filter Paper | Composite Fiberglass |
|---|---|---|
| Filter Lifespan | Moderate | Extended (High Dirt Capacity) |
| Pressure Drop | High Resistance | Low Resistance (Energy Saving) |
| Mechanical Strength | Prone to Tearing | High Strength (Reinforced) |
| Efficiency Range | Limited | Ultra-wide (15% - 99.99%) |
| Maintenance Cost | Frequent Replacement | Reduced Downtime |
Single-sided composite features a non-woven layer on one side, whereas double-sided has it on both. Double-sided offers maximum protection for the glass fiber core, increasing overall durability and strength.
For ultra-high efficiency, types like ZSU1 are recommended, as they offer filtration efficiency up to 99.99% for 0.3μm particles, though they have higher resistance.
The wet process allows for a more uniform distribution of ultra-fine glass fibers, resulting in consistent pore sizes and more stable air permeability across the entire sheet.
Yes, it is specifically designed for automotive engines and fuel turbines due to its high strength and ability to handle oil and chemical environments effectively.
Generally, a smaller mean pore size (e.g., 20μm in ZSU1) leads to higher filtration efficiency but also increases air resistance (e.g., 400 Pa), while larger pores (e.g., 150μm in ZS30) lower the resistance.
Absolutely. The material is engineered for heavy industry, including petroleum and chemical plants, where high mechanical stability and chemical resistance are required.
