In the realm of cleanroom technology and biosafety, maintaining pristine air quality is crucial. This is where YOUTH's innovative Bag-In-Bag-Out (BIBO) systems come into play, revolutionizing the way we handle contaminated filters, especially High-Efficiency Particulate Air (HEPA) filters.

What is a BIBO System?

A BIBO system is designed to safely replace contaminated hazardous filters without exposing personnel or the environment to the captured contaminants. Here’s a breakdown of its key components and features:

Key Components of a BIBO System

Filter Housing

The filter housing is a protective casing that holds the HEPA filter, allowing for safe replacement without exposure to contaminants.

Bag-in-Bag-Out Port

This feature connects the containment bag to the filter housing, ensuring airtight and safe handling of hazardous materials.

Differential Pressure Gauge

Equipped to monitor the pressure of the filter, ensuring optimal performance and safety. The gauge pipeline is made of stainless steel SUS 304 and includes an airtight isolating valve and highly efficient filters for sterilization.

PVC Bags

Specialized containment bags made of high-strength PVC, designed to prevent replacement and maintenance personnel from coming into contact with the filter. These bags are sealed with a patented special design-shaped rubber ring for a good locking effect.

On-site Disinfection Area

The system includes gas sterilization interfaces for on-site disinfection, ensuring the filter and surrounding areas are sterilized before and after replacement.

Leak Detector

HEPA filters undergo rigorous leak detection and filtration efficiency tests before use. The system may include manual or automatic leak detection capabilities to ensure filter integrity.

How Does a BIBO System Work?

The process is meticulous and designed for maximum safety:

Step-by-Step Procedure

1. Switch Off the Filtration System: Ensure the filtration system is off or the airflow is redirected to minimize exposure risk.
2. Equalize Pressure: Check that the internal pressure has equalized with the external pressure. Close isolation shutoff dampers if available.
3. Decontamination (if required): Perform decontamination procedures if the filter is in a bio-safety environment.
4. Remove the Old Filter: Place the contaminated filter into a specialized containment bag while still within the filter housing. Seal the bag to prevent particle escape.
5. Install the New Filter: Place the new filter into the safety bag, ensuring proper positioning and sealing. Check airflow and perform a DOP leak test after replacement.

Variations in BIBO Procedures

YOUTH's BIBO systems offer various levels of containment to suit different needs:

Single Bag BIBO

For less stringent containment requirements, a single bag is used to enclose and remove the contaminated filter.

Double Bag BIBO

A safer method involving a second containment layer, providing an extra level of protection against potential exposure.

Multiple Bag BIBO

For environments dealing with extremely hazardous materials, multiple bags can be used to ensure the highest levels of containment.

Safety Cabinet BIBO

Includes a safety cabinet or safe-change housing to further minimize the risk of exposure.

Portable BIBO Units

Designed to be portable, allowing them to be moved to the filter location, ideal for environments where filters are not centrally located.

Safety and Efficiency Features

Pressure Tolerance

BIBO systems can withstand various pressure differentials, often up to ±2500pa or higher, depending on the design specifications.

Leak Detection

Many BIBO systems include manual or automatic leak detection capabilities to ensure filter integrity and prevent potential leaks.

Filtration Efficiency

HEPA filters in BIBO systems have a filtration efficiency of 99.995%@MPPS for H14 filters, ensuring high air quality standards.

Applications and Benefits

Environmental Protection

Prevents the release of contaminants into the environment, safeguarding both personnel and the surrounding area.

Operator Safety

Ensures that maintenance workers are not exposed to hazardous particles during filter replacement.

Air Quality Maintenance

Critical for maintaining high air quality standards, especially in industries where clean air is paramount.
