The bag-in-bag-out high-efficiency air filtration unit (hereinafter referred to as the high-efficiency unit) is mainly used in high-level biosafety laboratory exhaust treatment systems. According to GB19489-2008 "General Requirements for Laboratory Biosafety", it should be possible to control the exhaust air in situ. The high-efficiency filter is designed to meet the prescribed requirements for disinfection, sterilization and leak detection, and is composed of functional parts such as aerosol detection section, mixing section, upstream sampling section, and scanning section.
This equipment uses line scanning leak detection technology to detect leaks in high-efficiency filters in situ, and realizes separate disinfection and sterilization of HEPA filters. It uses eccentric compression to load and unload filters and bag-in-bag-out replacement, which is safe and It is convenient and can display the high-efficiency filter resistance in real time, meets the requirements of biosafety standards, is easy to operate and maintain, and meets the needs of the construction of high-level biosafety laboratories in my country.
Bag-in-bag-out high-efficiency air filters appeared in the 1950s and 1960s, and are now widely used in various fields with high risks or high isolation requirements, such as chemical and biological (CB) protection, chemical, biological and radiological (CBR) Protection against Nuclearization. Biological and chemical (NBC) protection, hospital isolation rooms, pharmaceutical equipment, microelectronic environment, food processing areas, biological research. Genetics and Biotechnology Laboratory,
Industrial processing emission systems, chemical processing equipment, animal disease research and charging laboratories, radioactive isotope element processing equipment, nuclear power plants, strategic nuclear facilities, D.O.E equipment, military bases, etc.
