Fiberglass air filter paper is a critical component in modern air purification systems, offering exceptional performance in capturing airborne particles while maintaining low air resistance. Manufactured using advanced glass microfiber wool technology, this product is designed to meet the stringent demands of various industries, from residential HVAC systems to high-precision manufacturing environments. This article explores the features, technical specifications, applications, and the company behind this innovative filtration solution.
Fiberglass air filter paper is produced through a wet-forming method, ensuring a uniform distribution of fibers. This process results in a material with high dust-hold capacity, low resistance, and exceptional strength. The product is categorized into three main series based on filtration efficiency: ASHRAE, HEPA, and ULPA. Each series is tailored for specific applications, ranging from general air conditioning systems to ultra-clean environments in semiconductor manufacturing.
The fiberglass air filter paper is engineered to capture particles as small as 0.3 microns, making it ideal for environments requiring high air purity. The ASHRAE series (F5–F9) is suitable for general air conditioning systems, while the HEPA (H10–H14) and ULPA (U15–U17) series are designed for specialized applications such as pharmaceutical processing and semiconductor manufacturing.
With a basic weight of 70–73 g/m², the filter paper can retain a significant amount of particulate matter without compromising airflow. This feature reduces the frequency of filter replacements, offering cost-effective long-term performance.
The wet-forming process ensures a balanced structure that minimizes air resistance. For example, the ASHRAE F9 grade has an air resistance of 55 Pa at 5.3 cm/s, while the ULPA U17 grade maintains a resistance of 500 Pa, demonstrating its ability to handle high-efficiency filtration without excessive energy consumption.
The tensile strength of the material ranges from 1200 N/m, ensuring it can withstand the mechanical stresses of industrial and commercial applications. Its stiffness (≥1200 mg) further enhances its structural integrity, making it suitable for use in vacuum exhaust filters and air purifiers.
| Classification | Grade | Efficiency (%) | Basic Weight (g/m²) | Thickness (mm) @100kPa | Air Resistance (Pa) @5.3cm/s | Tensile Strength (N/m) | Stiffness (mg) MD |
|---|---|---|---|---|---|---|---|
| ASHRAE | FY-F9 | 95 | 70 | 0.34 | 55±10 | 1200 | 1200 |
| ASHRAE | FY-F8 | 90 | 70 | 0.34 | 35±5 | 1200 | 1200 |
| HEPA | FY-H14 | 99.995 | 70 | 0.34 | 340±20 | 1200 | 1000 |
| ULPA | FY-U17 | 99.9999 | 73 | 0.37 | 500±20 | 1200 | 1000 |
