WHY CAMFIL
For more than half a century, Camfil has helped people breathe cleaner air. As a leading manufacturer of premium clean air solutions, we provide commercial and industrial systems for air filtration and air pollution control that improve worker and equipment productivity, minimize energy use, and benefit human health and the environment. The best solutions for our customers are best for our planet, too.
The Bag in Bag out (BIBO) is filter housing is fully welded contsruction designed for critical air applications. A ribbed collar privides for PVC bag attachment with each unit’s door so easy access to servicing flters can be made without coming in contact with contaminated ones. A varirty of options can be provided for each units applications depending on the requirement of end user. Each section can be provided with a locking door for HEPA/ Adsorber section so no access can be made during operation of the system. These locked access doors can be opened to servicing HEPA or carbon adsorber section.
Bag in Bag Out housing are fully welded construction and all BIBO housings are factory pressure decay tested in accordance with ANSI/ASME-N510 1995, Pressure Vessel Code IX,. The units are tested at around +/- 10″WG to ensure there are no leakages or pressure loss through the housing structure. Bag in Bag Out housings normally accomodates HEPA or High efficient filters both at upstream and downstream locations to capture the particulates that encompasses the air stream.
Camfil FB Housing (fluid seal)
Camfil FB housings provide sealing integrity in a side access bag-in/bag-out housing for fluid seal Absolute® filters. FB housings are designed for applications in chemical manufacturing facilities, food processing, generic research and biotechnology facilities, hospital isolation suites, industrial process exhaust, microelectronic and semiconductor facilities, nuclear power plants, pharmaceutical facilities and more. The housings offer complete capture of airborne contaminants.

- Bag-In/Bag-Out (BIBO) HEGA-HEPA Filtration
Bag-in/Bag-out (BIBO) Filter Systems are specialty side-access filter housings that permit removal of the used air filters into a disposal bag. These heavy-duty disposal bags are mounted on collars underneath the filter access doors. When it’s time for filter change-out the filter access doors are removed, exposing these seam-welded bags that are secured onto the door collars. An elaborate procedure is followed to remove the used filters and then replace the filters, all completed without exposing the contaminants within the filter housing, when it is done properly. The housings themselves are constructed of Type 304SS or 316SS, to ASME N509 Nuclear Standard. The standard describes the construction, welding procedures and materials allowed on these specialty housings.
BIBO filter systems, by their nature, are used on critical applications where exposure to the dust, fumes or gases could be harmful (or possibly fatal) to service technicians. For that reason, these housings usually employ extremely high efficiency filters, such as HEPA (High-Efficiency Particulate Air), ULPA (Ultra-Low Penetration Air) or HEGA (High-Efficiency Gas-Phase Air) filter elements. Most BIBO filter systems are designed as multi-stage systems: Prefilter Stage(s), followed by HEPA/ULPA stage(s) and possibly HEGA filters (if there is a gaseous compound or radio-isotopes potentially in the gas-stream).
The BIBO system filter selections are dependent on the contaminants present and their concentration. Regardless of the contaminants, all filters are changed through the specialty bags, and all high-efficiency filters are sealed into the housing with heavy-duty clamping-mechanisms, to ensure there is no contaminants bypass around the filters. Often, these housings are provided with test apparatus to allow for challenge of the various high-efficiency filters in the housing, all completed without any exposure to potential contaminants within the air stream. It is also very common to see bubble-tight dampers installed on the opposed flanges of the housing to permit isolation of the filter housing/module when filter change-out is completed.
There are many applications for Bag-in/Bag-out (BIBO) filter systems, including, but not limited to:
- HVAC Systems in Nuclear Power Generating Stations
- Fume Hoods and Extraction Fans removing toxic fumes (Heavy metals, etc.)
- Pharmaceutical applications such as Cytotoxic drugs, high-potency or active ingredient manufacturing & packaging, etc.
- Hospital Air Isolation Rooms (AIR’s), and other negative pressure procedural suites such as Brachytherapy, Endoscopy are performed, but the air cannot be exhausted without possible re-entrainment.
- Cyclotrons require specialty BIBO filter systems with HEGA filters
