Fiberglass air filter paper has become a cornerstone in modern air purification systems, offering exceptional performance in a wide range of environments. Manufactured from glass microfiber wool using a wet-forming method, this filter media is engineered to provide high dust-hold capacity, low resistance, and high strength. Its versatility and efficiency make it an ideal material for applications ranging from household air conditioners to high-grade cleanrooms in semiconductor manufacturing. This article delves into the technical specifications, applications, and advantages of fiberglass air filter paper, while also highlighting the company behind this innovative product, Hebei Fangyu Filters Material Technology Co., Ltd.
Understanding the Product: Fiberglass Air Filter Paper
Fiberglass air filter paper is a specialized material designed to capture airborne particles effectively. Its unique composition of glass microfiber wool ensures a uniform fiber distribution, which enhances its ability to trap dust and contaminants. The wet-forming production method contributes to its low resistance and high intensity, making it suitable for both low- and high-efficiency filtration systems. This product is categorized into three main series based on filter efficiency: ASHRAE, HEPA, and ULPA, each tailored for specific applications.

- Low Air Resistance: Optimized for energy efficiency, reducing the load on HVAC systems.
- High Strength: Ensures durability in demanding environments, such as industrial cleanrooms or high-volume air exhaust systems.
- Customizable Efficiency: Available in multiple grades to meet specific filtration needs, from standard air conditioning to ultra-high-efficiency applications.
Technical Specifications: A Comprehensive Overview
The technical data for fiberglass air filter paper is detailed below, covering classification, efficiency, basic weight, thickness, air resistance, tensile strength, and stiffness. This table provides a quick reference for users to select the appropriate grade for their application.
| Classification | Grade | Efficiency (%) | Basic Weight (g/m²) | Thickness (mm) @100kPa | Air Resistance (Pa) @5.3cm/s | Tensile Strength (N/m) MD | Stiffness (mg) MD |
|---|---|---|---|---|---|---|---|
| ASHRAE | FY-F9 | 95 | 70 | 0.34 | 55±10 | 1200 | 1200 |
| FY-F8 | 90 | 70 | 0.34 | 35±5 | 1200 | 1200 | |
| FY-F7 | 80 | 70 | 0.34 | 33±5 | 1200 | 1200 | |
| FY-F6 | 60 | 70 | 0.33 | 20±5 | 1200 | 1200 | |
| HEPA | FY-H14 | 99.995 | 70 | 0.34 | 340±20 | 1200 | 1000 |
| FY-H13 | 99.97 | 70 | 0.34 | 290±20 | 1200 | 1000 | |
| FY-H12 | 99.8 | 70 | 0.34 | 250±20 | 1200 | 1000 | |
| FY-H11 | 98 | 70 | 0.34 | 120±20 | 1200 | 1000 | |
| FY-H10 | 94 | 70 | 0.34 | 80±15 | 1200 | 1000 | |
| ULPA | FY-U17 | 99.9999 | 73 | 0.37 | 500±20 | 1200 | 1000 |
| FY-U16 | 99.9999 | 73 | 0.37 | 440±20 | 1200 | 1000 | |
| FY-U15 | 99.999 | 73 | 0.37 | 390±20 | 1200 | 1000 |
The table above highlights the varied performance characteristics of fiberglass air filter paper across different grades. For instance, ULPA filters (e.g., FY-U15, FY-U16, FY-U17) are designed for ultra-clean environments, such as semiconductor manufacturing and pharmaceutical cleanrooms, where particle removal efficiency exceeds 99.999%. In contrast, ASHRAE filters (e.g., FY-F6 to FY-F9) are suitable for general air conditioning systems, gas turbine intakes, and vacuum cleaners, offering a balance between cost and efficiency.
Applications: Where Fiberglass Air Filter Paper Shines
The versatility of fiberglass air filter paper makes it suitable for a wide array of applications, including:
- Home Air Conditioners: Provides efficient filtration for residential HVAC systems, improving indoor air quality.
- Room Air Purifiers: Ideal for capturing fine particles, allergens, and pollutants in homes and offices.
- HEPA and ULPA Filters: Used in high-grade cleanrooms, pharmaceutical processing, and microelectronic manufacturing to meet stringent air quality standards.
- Industrial Applications: Employed in paint spray booths, photographic film manufacturing, and nuclear air exhaust systems for reliable particle removal.
- Personal Protective Equipment: Integrated into high-efficiency masks and vacuum cleaners to protect users from hazardous particles.
