Composite Fiberglass Filter Paper China Factory and Leading Suppliers
Composite Fiberglass Filter Paper is a high-performance filtration medium engineered from ultra-fine glass fibers using a precision wet-process manufacturing technique. By integrating ultra-fine glass fiber paper with specialized non-woven fabrics on one or both sides, this composite material provides a robust protective layer that shields the core glass fiber structure, ensuring exceptional structural integrity and longevity in the most demanding environments.
Designed for mission-critical applications, this material is characterized by its superior dirt-holding capacity, low flow resistance, and high mechanical strength. It delivers stable performance across various industrial sectors, making it an ideal choice for air compressors, automotive engines, fuel turbines, nuclear filtration, and natural gas engineering where precision and reliability are paramount.

The primary benefit is the addition of a non-woven fabric layer which protects the fragile glass fiber core, significantly increasing the material's strength and dirt-holding capacity while maintaining low flow resistance.
For maximum efficiency (up to 99.99% for 0.3U particles), the ZSU1 grade is recommended, although it has the highest resistance (400 Pa).
Yes, Composite Fiberglass Filter Paper is specifically designed for high-stability environments including nuclear filtration, aviation, and petroleum engineering.
Both-composite means non-woven fabric is applied to both sides of the glass fiber paper (thickness 0.5mm), whereas each-side composite is applied to only one side (thickness 0.4mm), offering different levels of structural support.
Air permeability increases as you move from ZSU1 (20 l/m².sec) to ZS30 (420 l/m².sec), allowing you to balance the needs of filtration efficiency against flow resistance.
Yes, all grades listed maintain a consistent tensile strength of 2 KN/m, ensuring mechanical reliability regardless of the filtration grade selected.
