Product Composition:

Designed in accordance with the requirements of GB19489-2008 "General Requirements for Laboratory Biosafety", JG/T 497-2016 "Exhaust High Efficiency Filter Device" and GB/T13354-2020 "High Efficiency Air Filter", it consists of upstream biosafety sealed valve, upstream variable diameter transition section, upstream aerosol uniformity system, high-efficiency filter clamping device, high-efficiency filter section, high-efficiency filter differential pressure detection system, bag in and bag out replacement system, in-situ scanning leak detection system, downstream variable diameter transition section, downstream biosafety sealed valve, circulating disinfection system, and disinfection verification port. 

Product Description: 

The unit type exhaust high-efficiency filtration device, also known as BIBO (Bag In Bag Out),uses a bag in bag out method to replace the high-efficiency filter. 

The bag in bag out (BIBO) pipeline exhaust and filtration device is mainly used in high-level biosafety laboratory exhaust and disposal systems. It is installed outside the laboratory protection area and connected to the laboratory through closed exhaust pipes. It can be used for in-situ disinfection and leak detection. This type of equipment can effectively prevent the leakage of pathogenic microorganisms into the external environment during use.
