What factors should I consider when choosing a horizontal or vertical flow cabinet?
What factors should I consider when choosing a horizontal or vertical flow cabinet?When choosing a horizontal flow cabinet or a vertical flow cabinet, you need to consider the following factors:1. Application scenarios and operation contents Type of experiment or production If it is the electronics industry, such as electronic component assembly, circuit board welding, and precision instrument debugging, a horizontal flow cabinet is a more suitable choice. Because these operations often require the handling of small, precise components, horizontal flow provides a stable, clean environment, and its open countertops facilitate the placement and operation of various electronic devices and tools. For the biopharmaceutical field, such as cell culture, microbial experiments, and drug preparation, a vertical flow cabinet is more suitable. The top-down airflow mode can effectively prevent external pollutants from entering the work area, protect the experimental samples from interference of external microorganisms, dust, etc., and ensure the accuracy of the experimental results and the quality of drugs. Manipulate the size and shape of the object. When the operating object is a large item, such as the assembly of a large electronic equipment shell, the preliminary processing of mechanical parts, etc., the open table of the horizontal flow cabinet has obvious advantages. It can easily accommodate these large items, will not be limited by space, easy for operators to operate around the full range of items. If the operation is small, environmentally demanding items, such as cell culture dishes, trace drug reagent bottles, etc., the vertical flow cabinet's quasi-closed table can provide better protection to prevent small dust particles and microorganisms from entering the work area from the side. 2. Working environment factors Space limitation The horizontal flow cabinet is usually more open in the horizontal space and is suitable for use in the laboratory or workshop with more spacious space. If the workspace is limited, especially the height space is limited, the vertical flow cabinet may be a better choice, because it mainly uses vertical space, and the horizontal space requirements are relatively small. Noise requirement The fan in the horizontal flow cabinet is usually located at the rear and produces relatively little noise when working. If the work environment is sensitive to noise, such as a small laboratory near the office or a place that needs a quiet working atmosphere, the horizontal flow cabinet will be a good choice. The fan with the vertical flow cabinet is located at the top and may produce a larger noise. In some environments where noise restrictions are not very strict, such as large industrial plants or laboratories with soundproofing facilities, the noise problem of vertical flow tables may not have much impact. Maintenance and cost factors Maintenance difficulty The structure of the horizontal flow cabinet is relatively simple, and the fan and filter are placed behind, which is convenient for maintenance and replacement of parts. Operators have relatively easy access to fans and filters for cleaning, servicing, or replacement. Vertical flow cabinet fans and filters are located on top, which can make maintenance more difficult. For example, when inspecting a faulty fan or replacing a filter, it may be necessary to use climbing equipment, and the structure of the top may limit the operating space of the maintenance personnel. Purchase cost and operating cost In terms of purchase cost, the price of horizontal flow cabinet and vertical flow cabinet will vary depending on the brand, specifications, features, and other factors. In general, in the case of similar functions, the price of a vertical flow cabinet may be slightly higher due to its better protection performance and relatively complex structure. In terms of operating costs, the main consideration is the energy consumption of the fan and the replacement frequency of the filter. The fan energy consumption of the two types of cabinets varies depending on the power and time of use, but if the fan power of the vertical flow cabinet is larger, it may consume more electrical energy. At the same time, the replacement frequency of the filter depends on the cleanliness of the working environment and the frequency of use, but the vertical flow cabinet may need to replace the filter more frequently due to high environmental protection requirements, thereby increasing the operating cost. |
