-
Modular Configuration for Flexible Assembly Based on Airflow and Installation SpaceThe BIBO system consists of multiple filter unit modules, assembled according to airflow requirements. Each module features a standardized size and structure. Core components include pre-filters, HEPA filters, service doors, change-out bags, scanning detection devices, and biosafety shut-off valves. Auxiliary elements such as pressure gauges, PAO aerosol dispersion units, and quick-connect ports ensure complete system functionality. These modules can be arranged flexibly to accommodate site constraints.
-
Versatile Biosafety Shut-off Valve OptionsThe BIBO system connects to the exhaust duct via biosafety shut-off valves, available in both rectangular and circular configurations to match customer ductwork requirements.
-
Precision Welding for Structural ReliabilityEach BIBO module is fabricated with CNC cutting, CNC lathe processing, and full-seam welding. Specially designed clamping mechanisms secure the filters in place, ensuring optimal sealing performance and structural strength.
The BIBO system is widely used in high-containment or hazardous exhaust scenarios, including:
- Chemical and biological (CB) protection
- Chemical, biological, and radiological (CBR) defense
- Nuclear, biological, and chemical (NBC) containment
- Hospital isolation rooms and pharmaceutical equipment
- Microelectronics production and food processing facilities
- Biological research and genetic engineering laboratories
- Industrial emission control and chemical processing systems
- Animal disease research labs and radioactive isotope handling
- Nuclear power plants, D.O.E. facilities, and military bases
The BIBO containment system ensures pollutants are not released during operation. All filter installations, replacements, and testing are conducted within a sealed change-out bag, fully isolating the filter unit from personnel and the surrounding environment, protecting both workers and public health.
In accordance with JG/T497-2016, GB19489-2008, and GB50346-2011 standards, every MayAir BIBO system undergoes comprehensive factory testing to ensure compliance with required safety protection levels. These tests include pressure resistance, enclosure leak tests, PAO scanning, and more. Each unit is delivered with accompanying BIBO and filter test reports.
Optional features such as manual or automatic PAO scanning, biosafety-sealed valves, and fumigation ports enable on-site leak detection and ventilation system decontamination based on customer requirements. MayAir BIBO systems have successfully passed P3/P4 biosafety compliance, performance testing, and disinfection validation, with inspection reports certified by accredited third-party institutions.
