Vertical Flow Clean Bench and Horizontal Flow Clean Bench are two kinds of workbenches aimed at different airflow directions, mainly used for supply high-cleanliness operation environment, widely applied in laboratories, pharmaceutical, micro-electronic production and so on. The main difference between them is the direction of air flow and the impact, as well as the take for use of different application cases.
The air is drawn from the top and blown downwards and the clean air at the side with the HEPA filter give a shower airflow to cover the working surface. Intended to generate nearly dust free downwash air curtain thus ruling out dust or any other particulate matter rising up.
Provides extremely high levels of cleanliness for operating environments that require a high degree of sterility or dust-free operation.
Offers outstanding shielding for functions like electronic component sorting and arrangement, cell culture included.
May capture particles produced by the operators below and transport them into the working area if the user is standing below.
Somewhat costly, due to higher power dense fans and more complex filters used to force the flow of water vertically up.
The airflow is from left to right across the HEPA filter, and across the top of the work bench. Ideal for longer worktop designs for more sample sizes or equipment to be incorporated.
They are generally cheaper than vertical flow benches, and therefore considered to be of high economic value.
Air flow direction favors larger flat surface operations such as chip inspection or printed circuit board assembly.
Ventilation openings across from the operator reduce the impact of airflow on the operator.
Accessibility of clean air at grassroots of the lab is vulnerable to interferences from the front of the bench in a case where the operator is operating directly in front of the airflow.
There may be vortices at the end of the airflow, which mean that some particles may be deposited to the work area.
Whether it is Vertical Flow Clean Bench or Horizontal Flow Clean Bench, they all have their unique advantages, there is no superiority or inferiority, the key is to match the most suitable application environment. The major point is in the combination with the appropriate application environment. Thus, regardless of the fact which Clean Bench has better usability, it all depends on the particular usage profile in addition to personal per disposition!
