Product Series and Applications
The Fiberglass Air Filter Paper is categorized into three primary series based on filter efficiency: ASHRAE, HEPA, and ULPA. Each series is tailored for specific applications, ensuring optimal performance in varied environments.
1. ASHRAE Series (F5–F9)
Designed for general air conditioning systems, the ASHRAE series is ideal for applications such as gas turbine air intakes, air compressors, and industrial ventilation. These filters offer moderate efficiency, balancing cost and performance for everyday use.
2. HEPA Series (H10–H14)
The HEPA (High-Efficiency Particulate Air) series is engineered for high-grade air purification. With efficiency rates of 99.97% to 99.995%, these filters are critical in cleanrooms, pharmaceutical manufacturing, and high-end HVAC systems. They are also used in nuclear air exhaust equipment and advanced vacuum cleaners.
3. ULPA Series (U15–U17)
The ULPA (Ultra-Low Penetration Air) series represents the pinnacle of filtration technology, achieving 99.999% to 99.9999% efficiency. These filters are essential in semiconductor manufacturing, biotechnology labs, and cleanrooms requiring 100-grade or higher air purity.
