Bag In Bag Out Filter is the Bag In Bag Out Filter, usually referred to as BIBO, also known as the duct type exhaust air filter device.
Since the filter has retained highly active or highly toxic harmful aerosols during the working process, it is necessary to ensure that the filter does not have any contact with the external environment during the replacement process, which can effectively prevent the harmful aerosols from spreading and avoid the production of organisms to the personnel and the environment. Hazard is a filter device used in a specific biological risk environment to remove harmful biological aerosols in the exhaust air.
At present, it is mainly used in high-level biosafety laboratories, hospital isolation rooms, pharmaceutical equipment, microelectronics environments, food processing areas, industrial processing exhaust systems, chemical processing equipment, air supply or exhaust air processing systems for animal disease research laboratories.
