Bag-in-Bag-out Filter Boxes in Hospitals

In specific applications such as industrial production or laboratories, infectious wards, etc., there is a need to treat the emission of exhaust gases, which can be quite dangerous, and these bag-in bag-out filters(BIBO) are used when dealing with the collection of hazardous exhaust gases. Bag-in-bag-out filter boxes are unconventional air purification devices that are often connected to the exhaust system to prevent the leakage of, and exposure to, contaminants in the ward, thus protecting the operator's safety and the outdoor environment.

Principle:

BIBO itself can't treat the exhaust gas, it can only collect the hazardous exhaust gas through the filter, and this collection process will not produce leakage, and the staff who maintains and replaces the filter will not come into direct contact with the exhaust gas, and the installation and replacement of the filter will be isolated by the bag, the filter that is replaced will be handed over to the specialised treatment department for disposal.

Bag-in-bag-out filter boxes are commonly used in the pharmaceutical engineering industry, biosafety laboratories and hospitals. They are mainly used in the exhaust section of ventilation systems to treat contaminated air and prevent it from leaking out and causing harm to the environment.

As society continues to develop and hospital facilities and configurations continue to improve, bag-in bag-out filter boxes for the exhaust section of the ventilation system are beginning to appear more often in the project list. Bag-in-bag-out filter box is a special exhaust equipment, usually used in negative pressure isolation wards or other special wards of the exhaust section. The change of bag-in-bag-out filters not only protects the operator from contaminated air, but also protects the outdoor environment from contamination.

The bag-in-bag-out filter box of the hospital is usually installed in the top floor of the building or in the interlayer of the ventilation duct, in which more cases are installed in the top floor. The main reason is that the top floor has enough space, which is conducive to reducing the noise in the hospital, and there is more space for installation and maintenance, which is convenient for the construction personnel to operate. It is recommended that bag-in bag-out filter cases installed on the top floor be equipped with rain shelters, so as to slow down the deterioration of the instruments and the sealing plastics.
