What is the HEPA filter material?
HEPA high-efficiency filters are often divided into five filter materials: PP filter paper, glass fiber, composite PPPET filter paper, melt-blown polyester non-woven fabric and melt-blown glass fiber. Features: Large wind resistance, large dust holding capacity, high filtration accuracy, H14 hepa Filter Material manufacturer, can be processed into various sizes and shapes according to customer needs, suitable for different models.
HEPA is an acronym for High Efficiency Particulate Air Filter. HEPA filters are often called high efficiency air filters in China. The filtration efficiency of the HEPA filter is particularly high, air can pass through, but small particles cannot.
For a diameter of 0.3 microns (1/200 of the diameter of a hair), the particle removal efficiency of HEPA filters exceeds 99.7%. It is the most effective smoke, dust and bacteria filter media on the market. (smoking smoke particle diameter of 0.5 microns) is also considered to be the most efficient filter material internationally. It is widely used in high clean places such as operating room, animal laboratory, crystal experiment and aviation.
HEPA Filter History:
The original HEPA filters were designed in the 1940s for the Manhattan Project to prevent the spread of radioactive pollutants in the air. It was commercialized and became a registered trademark in the 1950s, and its collective name is a particularly effective filter. Over the past decade, filters have continued to evolve to meet the higher and higher air quality demands of various high-tech industries such as aerospace, pharmaceutical processing, hospitals, healthcare, nuclear fuel, nuclear power, and electronic microcircuits (computer chips).
Rating DOE regulated application of HMCA filters. Products marked as “HEPA type”, “HEPA” or “99% HEPA” may not meet these requirements in independent laboratories and may not be tested. HEPA high efficiency filter, it is widely used in optical electronics, LCD liquid crystal manufacturing, Biomedicine, precision instruments, film and optical fiber equipment, PCB printing and other industries in the dust-free purification workshop of the air-conditioning end of the air supply.
HEPA High Efficiency Filter Production Features:
1.) Because of the unique seamless sealing technology, the sealing effect is better than ordinary filters, which is more durable and not easy to leak.
2.) The safety is very high, and the filter material has a metal mesh on both sides.
3.) Available in 46mm, 50mm, 69mm, 80mm, 90mm and other thicknesses.
4.) Laser scanning and counting MPPS efficiency: 95%-99.999995% (EN1882).
5.) There are many levels of filtering: H11-H14, U15, U16 (EN1882).
Performance Characteristics and Applications of HEPA High Efficiency Filters:
The filtration efficiency of >0.3um particles is above 99.97%.
Because it is a computer-controlled automatic folding machine system for glue spray folding, the folding height can be adjusted stepless between 22 and 96 mm. Its filter material is made of special glass fiber filter paper. Each filter is strictly inspected and adopts international standard size specifications.
