Pharmaceutical production environments place extremely high requirements on air cleanliness and pollution control. During the production process of active pharmaceutical ingredients (API), vaccines, biological products and sterile pharmaceuticals, particulate matter, microorganisms and harmful pollutants in the air must be effectively controlled.
During the traditional air filter replacement process, the contaminated filter may be exposed to maintenance personnel and the surrounding environment, increasing the risk of contamination transmission.
Bag-in-bag-out filter box (Bag-In-Bag-Out, referred to as BIBO) is a safety filtration equipment specially used in high-risk environments. It uses a closed bag replacement method to achieve full isolation during filter removal and installation.
Why does the pharmaceutical industry need bag-in-bag-out filter boxes?
There are a large number of application scenarios that require strict pollution control in the pharmaceutical production process, including:
Sterile pharmaceutical production
Vaccine manufacturing
Biopharmaceutical laboratory
API production (API)
Highly active drug production
During long-term operation, HEPA filters will continuously capture particles, microorganisms and pollutants in the air. When the filter reaches the end of its service life and needs to be replaced, contaminated filter elements may become a potential source of risk.
BIBO filter box can effectively solve this problem:
Avoid personnel from direct contact with contaminated filters
Protect the safety of maintenance personnel
Reduce the risk of cross-contamination
Ensure the safety of the clean room maintenance process
Working principle of bag-in-bag-out filter box
The BIBO system adopts a continuous sealed bag structure to achieve safe replacement of filters.
The basic replacement process is as follows:
Enclose the contaminated filter in a special replacement bag;
Remove the old filter in a sealed state;
Install a new filter through the clean side;
Seal the waste filter bag and remove it safely.
The entire process avoids direct exposure of contaminants, so that the filter replacement process is always under control.
