Fiberglass Air Filter Paper is widely used across industries due to its versatility and high performance. Key applications include:
The Fiberglass Air Filter Paper is categorized into three main series based on filtration efficiency:
Designed for general-purpose applications, the ASHRAE series is commonly used in ordinary air-conditioning systems, gas turbine air intakes, and compressors. It offers moderate filtration efficiency, making it suitable for environments where basic air quality control is required.
The HEPA series provides high-efficiency filtration, capturing 99.97% to 99.995% of particles as small as 0.3 microns. This series is essential for 10,000 to 100,000 grade cleanrooms, nuclear facility exhaust systems, and high-end consumer air purifiers.
The ULPA series represents the pinnacle of filtration technology, achieving efficiencies of up to 99.9999%. It is used in 100, 10, or even 1-grade cleanrooms in industries like microelectronics, pharmaceuticals, and biotechnology, where contamination control is critical.
