Every step in a high-level biosafety lab carries pathogen leakage risk. The Bag-in Bag-out (BIBO) containment system is the critical line of defense.   Mayair recently delivered a full-line Mayair BIBO containment system solution for a top-tier biosafety lab in Wuhan. Over 100 BIBO units were deployed, covering fresh air intake to exhaust treatment. Using a "constant supply, variable exhaust" control strategy, the system effectively traps pathogenic aerosols and ensures compliant emissions.   Three Unbeatable Advantages of Mayair BIBO   Modular Design for Any Space   Not a one-size-fits-all product. Our Bag-in Bag-out filter housing matrix adapts to vertical/horizontal installation and tight spaces without compromising filtration performance.     Laser Full Welding for Zero Leakage   Absolute sealing is non-negotiable for biosafety. All welds are formed in a single pass, eliminating micro-leaks. Paired with polymer-sealed replacement bags, operators never contact contaminants during HEPA filter changes.     Dual Detection with Full Traceability   100% factory airtightness testing before delivery. On-site PAO scanning verifies filter and frame seal integrity point by point. All test data is documented and fully traceable.       With 20+ years of expertise in high-grade air purification, Mayair provides reliable protection and full lifecycle support for biosafety facilities. We continue to advance sealing technology and testing standards to safeguard public health and cutting-edge research.
