The clean bench is designed to adapt to modern industry, optoelectronics industry, biopharmaceuticals, and scientific and research experiment field, which has a requirement of the cleanliness of the work area. It would suck the air into the pre-filter through the fan, then the air enters into the high-efficiency filter via a static pressure box. The filtered air would be sent out in a state of vertical or horizontal airflow, so the working area can realize 100-level cleanliness, which is an ideal and reliable environment for production, experiment, pharmacy, and etc. CLS031 is the workbench that has its own filtered air supply. The clean bench’s main point is that it can effectively protect work from contamination. And it is equipped with the HEPA filter system that plays an important role in protecting the work area. It can remove particulates, generally called aerosols, such as micro-organisms, from the air. It is widely used in a variety of applications throughout medical research laboratories, hospitals, manufacturing facilities, and other research and production environments.
