The bag in bag out filter box is a commonly used exhaust device in the pharmaceutical industry and biosafety laboratories. The fully enclosed bag in and bag out design can effectively isolate the pollution of radioactive gases, pathogens and chemicals. It effectively prevents secondary air pollution and ensures the safety of operators.
Applications
Bag in and bag out filter box(BIBO) is a filtration system for safety protection, which is generally connected to the exhaust system to prevent the leakage of harmful substances and pollutants. It is applied to the replacement of air filters or chemical filters in hazardous environments, which provides a safe and reliable replacement method. The replacement of the filter is carried out in the protective bag, which can avoid the contact between the gas in the box and the outside world, so as to protect the safety of the operator and the environment. The protective bag is equipped with gloves to facilitate the staff to do the replacement operation. The main application areas are as follows:
- Pharmaceutical engineering ( Vaccine production workshop exhaust, vaccine workshop animal room exhaust, hormone, cytotoxin drug production workshop exhaust, high activity chemical production workshop exhaust, anticancer preparation production workshop exhaust, isolation equipment exhaust );
-
Pharmaceutical laboratory;
-
Biomedical research and genetic engineering facilities;
-
Toxic waste from animal disease isolation room isolation plant;
-
Nuclear power plants and fuel treatment facilities;
-
Biosafety laboratory ventilation, hospital isolation area ventilation, industrial chemical gas emissions;
Composition and construction:
The composition of BIBO filter is similar to combined air-conditioning unit, which is to combine different functional units into the bag in/bag out Housing (BIBO Housing) according to the demand of use. Common functional units include: Pre-filter, High Efficiency Particle Filter (HEPA), High Efficiency Gas Adsorption Filter (HEGA), Precision Scan test Sections, etc.
Under normal circumstances, BIBO filter consists of two parts, filter unit and detection unit. The most simple filtration unit contains only high efficient particle filter, if the air is not filtered before entering BIBO filter, pre-filters must be used to protect the high efficient particle filter. If the filter gas need adsorption filtration, then high efficiency air adsorption filter is needed; Detection unit refers to an automatic (or manual) precision scan test sections.
In addition to the above main components, there are some supporting equipment on BIBO Housing, such as pressure gauge, pressure hole, quick connection port, etc.. Micro high efficiency particle filters are used between these components and the BIBO housing, to ensure good isolation effect from the outside. BIBO filter and the bubble tight isolation dampers constitute a complete air filtration and isolation system, which is called "Containment Systems" in North America.
BIBO adopts the design of single or multiple filtration system: single filtration system only has a high efficiency filter; the multiple filtration system can increase the primary and middle efficiency filtration section, chemical filtration section, activated carbon filtration section and double high efficiency filtration section.
Product advantages:
- The most important feature of BIBO is that the installation, replacement and detection of the filter are all carried out under the protection of a PVC bag (or high temperature bag). The filter unit does not contact with the outside air completely, so as to ensure the safety of personnel and the environment and make the replacement process convenient and fast.
-
The standard installation method of BIBO box is horizontal.Vertical installation or other installation methods can be customized;
-
Optional filter, choosing large air volume or PTFE high strength filter, which is impact-resistant and can prevent filter damage. The air volume of box filter can be up to 4000CMH, and PTFE efficiency up to U16(EN1822);
| Air volume |
up to 4000CMH |
| PTFE efficiency |
up to U16(EN1822) |
-
The filter replacement is simple and reliable, which adopts rapid compression to press the filter and reduce some steps such as tightening bolts. It is convenient for operation in the bag and ensures the reliability of pressing. Equipped with auxiliary mobile device, it is easy to replace the filter ;
-
The box is fixed and has strong compression resistance. The box adopts 304 stainless steel or good cold rolled steel (electrostatic spraying), and the resistance pressure is 2500 Pa positive pressure and 3000 Pa negative pressure.
-
Modular design, compact structure, convenient transportation, the use of building blocks superimposed installation design to meet the requirements of large volume air filtration, which can be superimposed on three layers to effectively save the installation space;
