The Bag-in Bag-out (BIBO) system is mainly used for chemical and biological (CB) protection, P3/P4 laboratories, and the pharmaceutical industry. It is a safety protection filtration system connected to exhaust systems, which allows for the installation, replacement, and testing of air or chemical filters in hazardous environments within a secure protective bag (PVC bag or high-temperature bag). This method not only protects the operators from contamination by harmful substances but also prevents the filters from coming into contact with the external air, ensuring the safety and convenience of the replacement process. The protective bags are also equipped with gloves, allowing the staff to easily carry out replacement operations.

We are the first company in China that has recognized the importance of upstream concentration uniformity in BIBO systems, and the very first to pass this stringent test.
