More Cleanroom Technology has developed to protect the work from contamination and the clean bench is one important one. In recent years, the use of the clean bench, laminar flow cabinet or laminar flow hood has spread from research and manufacturing to other fields such as aerospace, bioscience, pharmaceutical production and food processing. Now let's get to know the answer of what is clean bench. Today, with the development of science and technology, the clean benches are used in a variety of applications throughout medical research laboratories, hospitals, manufacturing facilities and other research and production environments.
What is clean bench? Firstly, you should know its function. The clean bench provides product protection by ensuring that the work in the bench is exposed only to HEPA-filtered air. The clean bench is recommended for work with non-hazardous materials where clean, particle-free air quality is required. Moreover, it does not provide protection to personnel or to the ambient environment and it is not designed to contain aerosols generated by the procedure; the user is exposed to these aerosols.
What is clean bench? A common component in any clean bench is the HEPA filter. The HEPA filter removes particulates, generally called aerosols, such as micro-organisms, from the air. HEPA filters are made of boron silicate microfibers formed into a flat sheet by a process similar to making paper. Flat filter sheets are pleated to increase the overall surface area. Pleats are separated by aluminum baffles which direct the airflow through the filter. Depending on its quality, a HEPA air filter can trap from 9,997 to 9,999 of every 10,000 particulates of a diameter greater than and less than 0.3 micron. For most industrial uses, the 99.97% performance is acceptable. Pharmacy and laboratory applications, however, require a 99.99% filtration performance level.
What is clean bench? Another common attribute in Clean Bench technology is laminar airflow. Generally defined, laminar airflow is airflow in which the entire body of air within a confined area moves in a unidirectional velocity along parallel flow lines. Technically defined, laminar airflow is the fluid flow in which air velocities are free of macroscopic fluctuations which occur when the Reynolds Number is less than 2000. After learning the information above, you may know what Clean Bench is. Various types of clean benches are available that can serve as a more economical means to achieving specific cleanroom class areas within a critical environment.
