CBC - Flexible-Film Containment Units for Hazardous Materials

Class Biologically Clean (CBC) specializes in manufacturing flexible-film containment units designed for negative pressure environments to safely handle highly pathogenic organisms and potent compounds. These units are not designed with laminar airflow, instead, they offer a fully enclosed space that ensures the protection of workers and the surrounding environment. Incorporating heavy-duty 20 mil. polyurethane material, CBC units are highly resistant to punctures and tears, reducing the risk of contamination. The units come with HEPA and optional ULPA filters to ensure purified air handling. Customization options include various configurations to fit existing BSL 3 labs or accommodate specific equipment needs, such as storage, weighing, or milling hazardous materials. CBC provides diverse transfer port options made from stainless steel, acrylic, or polypropylene, with designs that meet high-risk containment standards. These containment units serve industries such as pharmaceuticals and research facilities requiring robust isolation and contamination control measures.

You Should Consider the Cost Saving Advantages of Flexible Film (Softwall) Containment Units for the Containment of Highly Pathogenic Organisms or Potent Compounds

CBC will design a flexible film (softwall) containment unit or bio-isolator system that will meet your requirements.

Our softwall, restricted access barrier containment units are designed to protect workers and prevent the release of highly pathogenic organisms or highly potent compounds into the surrounding environment.

For researchers, CBC has manufactured flexible film containment units for containment of pathogens such as the H5N1 (the avian influenza), H1N1 (the swine influenza) and Bacillus anthracis (anthrax); and for necropsy tables to prevent the potential spread of organisms during a necropsy.

For the pharmaceutical industries, CBC has designed units for potent compound storage, weighing, milling and exhaust collection.

CBC can design a flexible film unit to fit inside your current BSL 3 lab or around an existing piece of equipment.

Some of the features of the CBC softwall (flexible film) containment units include:

System is run under negative pressure.
A totally contained chamber, the system does not use the laminar airflow design (the chamber is completely enclosed).
HEPA inlet and outlet filtration system.
Large removable doors for moving caging or supplies in and out of the unit.
Portable.
Air handing system will automatically turn off the inlet supply when the door is opened or the pressure increases to almost the ambient room pressure, thus maintaining the negative or inward airflow.
Durable 20 mil. polyurethane for sidewalls and ceiling.
Strong 30 mil. polyurethane flooring (can stand up to heavy caging systems).
Lap Seam construction.
Resealable snap loops for easy assembly and disassembly.
1 1/2" annodized aluminum tubing used for frame.
Provides a restricted access barrier.

Optional equipment:

Water and electrical supply lines.
Environmental monitoring, 24/7 monitoring of items like air pressure, airflow, temperature, and humidity.
LED read outs.
Wheels for mobility.
Air handing system that will automatically turn off the inlet supply when the door is opened or the pressure increases to almost the ambient room pressure; thus, maintaining the negative or inward airflow.
Airtight divider panels.
Shower-in and/or Shower-out antechambers.

Filter and Transfer Port Options:

Each flexible, barrier isolator system comes with a HEPA filter on the inlet and exhaust. An attachment can be added to the exhaust filter housing to allow for exhausting into the building's exhaust system. Alternatively, a second HEPA filter can be added to the exhaust system to allow venting back into the room. ULPA filters are also available.

The transfer port systems come in stainless steel, acrylic, or polypropylene. The design can be the conventional system with two (2) removable vinyl caps or a rapid transfer port system.
