The different factory air quality requirements differences are not the same. Factory equipped with a fume hood and pollution control equipment need to add a lot of air, these factories where the ambient air is contaminated, it will complem ent the air distribution to the workplace before must be filtered. Demanding semiconductor manufacturing and pharmaceutical industries, the cleanliness of the air. In a typical working environment, containing 500,000 particles per cubic foot of air, while the latest requirements of the semiconductor production is only one particle per cubic foot of air. The workplace needs clean air filtered through HEPA filters constantly cleaning cycle. In order to maintain the cleanliness of the HEPA filter and lifetime, also need the paragraphs less efficient pre-filter used in combination.bag filter Industrial cleanroom requirements continuously and effectively remove the smaller particle size of the particles. HEPA filter once the highest efficiency of the filter, now UL PA filter is the highest efficiency of the filter, after a new generation of more efficient filter will also be able to develop applications. The fine glass fiber filter medium is the filter medium of the main choice, but the film and an electrostatically enhanced media have penetration of the field, and to obtain the part of the application. Factory emissions, the most stringent requirements are toxic. Certain heavy metals such as mercury, arsenic, chromium, beryllium is very toxic, very strict emission limits. Therefore, prior to the discharge of these gases have been a series of filtering processing. In terms of air toxicity, the United States and Germany have adopted a new and more stringent legislation. After the implementation of the new legislation, the the air toxicity limit from 20 mg / m 3 (standard) to reduce to 010 004 mg / m 3 (standard). To achieve this goal, the plant requires a more advanced filter to remove submicron particles. Some German company uses a conventional folding-type fine glass fiber HEPA filter for the filtration system, and to cooperate with the pulse clean air mechanism, and a corrugated filter media is more dense. A U.S. company through the design of tubular micro glass fiber HEPA filter Youxiang a step forward.House wrap
