Classification of clean benches
The clean bench is divided into vertical flow clean bench (vertical flow clean bench) and horizontal flow clean bench (horizontal flow clean bench) according to the direction of the airflow. The vertical flow bench is noisy because the fan is on the top, but the wind blows vertically and is mostly used in medical engineering. In this way, people's health is guaranteed; the horizontal flow workbench has relatively low noise and winds outwards, so it is mostly used in the electronics industry and has little effect on health. According to the operation structure, it can be divided into two forms: unilateral operation and bilateral operation. According to its purpose, it can be divided into ordinary dust-free workbench and biological (medical) dust-free workbench.
From the number of operators, it is divided into single clean benches and double clean benches; from the structure, it is divided into two types: bottom suction and top suction; from the air supply, it is divided into horizontal air supply and vertical air supply.
