What is the difference between a vertical flow clean bench and a horizontal flow clean bench

The clean workbench is divided into vertical flow clean workbench and horizontal flow clean workbench according to the direction of air flow, vertical flow work station fan at the top, noise is larger, wind vertical blowing is mostly used in medical engineering, vertical flow wind to ensure people's health; The horizontal flow workbench is less noisy, the wind is outward, and it is mostly used in the electronics industry
.
1, horizontal laminar flow clean workbench: is a kind of local clean workbench with strong versatility, it is widely used in electronics, national defense, precision instruments, instruments, pharmaceutical industry, etc
.
2.
Vertical laminar flow cleaning table: Vertical one-way flow cleaning table is widely used in areas
that need local cleaning.
Laboratory, biopharmaceutical, optoelectronic industry, microelectronics, hard disk manufacturing and other fields
.
Both the horizontal air supply and vertical air supply workbenches can meet the experimental needs, and the air flow type to be considered is the air flow type (according to the experiment, which form of air supply has little impact on the experiment).

Generally vertical; Vertical air supply is vertical downward blowing, vertical manifold, quasi-closed tabletop, can effectively prevent the external confluence penetration and operation of odor on the human body stimulation
.
If the microscope is placed in the workbench, the vertical air supply air flow will be blocked by the microscope, in which case the horizontal wind should be selected; But the general experiment is vertical, and the glass door is generally moved up and down
.
In general, there is no obvious difference between horizontal and vertical air supply, and the appropriate type
is selected according to the experimental requirements.
