Chemical raw material weighing room

Negative pressure weighing chamber is a kind of local purification equipment with important application value in the fields of pharmaceutical, microbiological research and scientific experiment. In this article, we will analyze the working principle of negative pressure weighing room to help you better understand and apply this equipment. Negative pressure weighing room working principle equipment using vertical unidirectional flow of airflow form, the return air first through the primary filter for pre-filtration, the airflow of large particles of dust particles to deal with. After pre-treatment of the air, then through the intermediate filter for secondary filtration, in order to play a role in fully protecting the high-efficiency filter. Under the pressure provided by the centrifugal fan, it passes through the high-efficiency filter to meet the clean requirements. The operation area and the external environment form a relative negative pressure, thus ensuring that the dust in this area will not spread to the outdoors, and play a role in protecting the external environment.
