The working principle is: through the fan will air into the pre-filter, through the static pressure box into the high-efficiency filter filtration, the filtered air to the vertical or horizontal airflow state to send out, so that the operating area to achieve a hundred cleanliness, to ensure that the production of environmental cleanliness requirements. Ultra-clean bench according to the direction of airflow is divided into vertical flow ultra-clean bench (Vertical Flow Clean Bench) and horizontal flow ultra-clean bench (Horizontal Flow Clean Bench), according to the operating structure is divided into one-sided operation and bilateral operation of two forms, according to its use can be divided into ordinary ultra-clean bench and biological (pharmaceutical) ultra-clean bench. The workbench can be divided into two forms according to the operation structure, one-side operation and two-side operation.
The principle of ultra-clean bench is in a specific space, the indoor air by the pre-filter primary filtration, by a small centrifugal fan pressed into the static pressure box, and then by the air high-efficiency filter secondary filtration, from the air out of the high-efficiency filter surface of the clean air flow with a certain and uniform cross-section of the wind speed, you can exclude the original air in the work area, dust particles and biological particles to take away, in order to form aseptic high-clean working environment. The working environment is highly clean and sterile.
