How to choose a stainless steel clean bench

Clarify the cleanliness requirements of the working environment, and determine the required cleanliness level according to industry standards or your production process requirements.
Different industries and application scenarios have different standards for cleanliness. For example, pharmaceutical production, electronic manufacturing, food processing, and other fields have high requirements for air cleanliness. When choosing a stainless steel clean bench, it is necessary to determine the required cleanliness level, such as ISO Class 5, Class 6, etc., according to industry standards or the needs of your production process, and ensure that the selected workbench can meet or exceed this standard.
Consider the material and structure of stainless steel, select the appropriate stainless steel material according to the type and concentration of corrosive substances in the working environment and the budget, and pay attention to whether the structural design of the workbench is easy to disassemble, clean, and maintain.
Stainless steel has become the main material choice for clean workbenches due to its excellent corrosion resistance and easy cleaning. However, there are many types of stainless steel, such as 304, 316, etc., and each material has differences in corrosion resistance, mechanical properties, and cost. Therefore, it is necessary to select the appropriate stainless steel material according to the type and concentration of corrosive substances in the working environment and the budget. At the same time, the structural design of the workbench is also crucial. Consider whether it is easy to disassemble, clean, and maintain and whether it can effectively prevent the accumulation of dust and microorganisms.
Pay attention to the filtration system, determine the required filtration level according to the cleanliness requirements, pay attention to the replacement cycle and maintenance cost of the filter, and some clean workbenches are also equipped with molecular filters.
The filtration system is one of the core components of the clean workbench and directly affects the air quality of the working area. At present, the common filtration systems on the market include primary filters, medium-efficiency filters, and high-efficiency filters (HEPA), among which HEPA filters can filter out particles larger than 0.3 microns in the air to achieve higher cleanliness. When choosing, it is necessary to determine the required filtration level according to the cleanliness requirements and pay attention to the replacement cycle and maintenance cost of the filter. In addition, some clean workbenches are also equipped with molecular filters, which can further remove harmful gases and volatile organic compounds (VOCs) in the air.
Consider the airflow pattern. Common airflow patterns include vertical laminar flow, horizontal laminar flow, and vortex airflow. Choose the appropriate airflow pattern according to different application scenarios.
The airflow pattern is one of the key factors affecting the performance of the clean workbench. Common airflow patterns include vertical laminar flow, horizontal laminar flow, and vortex airflow. The vertical laminar flow mode is suitable for occasions with high requirements for air cleanliness, such as microbiology laboratories; the horizontal laminar flow mode is more suitable for scenarios with high requirements for operator protection, such as chemical workbenches; the vortex airflow mode uses a special airflow design to reduce the disturbance of the airflow inside the workbench and improve the cleanliness.
