In the construction of Class 10,000 clean workshops, the selection and design of the airflow pattern are crucial elements to ensure that the workshop meets strict cleanliness standards. As a professional constructor, Guangzhou Cleanroom Construction Co., Ltd. is well aware of the significant impacts of different airflow patterns on the cleanliness of the workshop, the uniformity of temperature and humidity, as well as energy consumption. The following will delve into the standard airflow patterns in Class 10,000 clean workshops and the professional considerations of Guangzhou Cleanroom Construction Co., Ltd. in practical applications. I. Overview of Class 10,000 Clean Workshops   A Class 10,000 clean workshop refers to a clean production environment where the number of dust particles with a particle size ≥ 0.5μm per cubic meter of air does not exceed 352,000, and the number of dust particles with a particle size ≥ 5μm does not exceed 2,930. It is widely used in industries with high requirements for the production environment, such as electronics, pharmaceuticals, food, and optics. In such workshops, even tiny dust particles and microorganisms can have a significant impact on product quality. Therefore, a reasonable airflow organization is essential for maintaining the cleanliness of the workshop. II. Common Airflow Patterns (I) Unidirectional Flow 1. Vertical Unidirectional Flow   Airflow Principle: Vertical unidirectional flow means that the air flows vertically downward from the top of the workshop at a uniform speed and in a single direction, and then is discharged from the ground. This airflow pattern is like an "air piston", quickly pushing out pollutants such as dust particles and microorganisms, thus maintaining a highly clean environment in the workshop. Application Scenarios: It is often used in areas with extremely high cleanliness requirements, such as the photolithography process workshop in electronic chip manufacturing. During the photolithography process, even the tiniest dust particles can cause short circuits in the chip circuits or a decrease in photolithography accuracy. Vertical unidirectional flow can minimize the contamination of dust particles on the chip and ensure the high-precision requirements of chip manufacturing. Design Highlights of Guangzhou Cleanroom Construction Co., Ltd.: When designing a vertical unidirectional flow system, Guangzhou Cleanroom Construction Co., Ltd. pays attention to the layout of the air supply outlets and air return outlets. The air supply outlets usually adopt the form of full coverage with high-efficiency filters to ensure that the supplied air has extremely high cleanliness. The air return outlets are evenly distributed on the ground to ensure the smooth discharge of the airflow. At the same time, the air supply volume and wind speed are accurately calculated. Generally, the wind speed is controlled at 0.3 - 0.5m/s to ensure that the air can effectively carry away the pollutants and will not generate excessive airflow disturbances. 2. Horizontal Unidirectional Flow   Airflow Principle: In horizontal unidirectional flow, the air flows horizontally from one side of the workshop to the other side at a uniform speed. Similar to vertical unidirectional flow, it carries away pollutants through the directional flow of air to maintain the cleanliness of the workshop. Application Scenarios: It is more common in some large electronic display manufacturing workshops. Since the display screen has a large area, horizontal unidirectional flow can provide uniform clean air in a large horizontal space, meeting the requirements of the clean environment during the production process of the display screen. Design Highlights of Guangzhou Cleanroom Construction Co., Ltd.: When designing horizontal unidirectional flow, Guangzhou Cleanroom Construction Co., Ltd. will reasonably arrange the air supply outlets and air return outlets according to the length and width of the workshop. The air supply outlets are generally set above the wall on one side of the workshop, and the air return outlets are set below the wall on the other side. At the same time, considering the attenuation of the air during the flow process, the wind speed of the air supply outlets will be reasonably adjusted to ensure that sufficient cleanliness can be maintained at the far end of the workshop. (II) Non-unidirectional Flow (Turbulent Flow)   Airflow Principle: The airflow movement direction of non-unidirectional flow is irregular, and there is a certain degree of turbulence. After the air is sent out from the air supply outlet, it forms a mixed and stirred airflow state in the workshop, diluting the dust particles and discharging them out of the workshop. Application Scenarios: It is suitable for areas in Class 10,000 clean workshops with relatively lower cleanliness requirements, such as the drug packaging workshops of some pharmaceutical enterprises and some process areas of food processing workshops. Although these areas have requirements for cleanliness, compared with processes such as chip manufacturing, a certain degree of dust particles is allowed to exist. Design Highlights of Guangzhou Cleanroom Construction Co., Ltd.: When designing a non-unidirectional flow system, Guangzhou Cleanroom Construction Co., Ltd. will reasonably select the type and quantity of air supply outlets according to the function and layout of the workshop. Diffusers or louver outlets are usually used as air supply outlets. By adjusting the angle and wind speed of the air supply outlets, a relatively uniform turbulent airflow state can be formed in the workshop. At the same time, the position and quantity of the air return outlets are reasonably set to ensure that the air containing pollutants can be effectively discharged. In addition, to improve the cleanliness, the air change rate is increased. Generally, the air change rate of a Class 10,000 non-unidirectional flow clean workshop is 15 - 25 times per hour. (III) Mixed Flow   Airflow Principle: Mixed flow combines the characteristics of unidirectional flow and non-unidirectional flow. Unidirectional flow is adopted in the key areas of the workshop to ensure high cleanliness requirements, while non-unidirectional flow is used in other areas to meet the air change needs of a larger space and reduce costs. Application Scenarios: It is widely used in some large comprehensive electronic factory clean workshops. For example, unidirectional flow is adopted in the core process areas of chip manufacturing to ensure the high cleanliness of the chip production environment; while non-unidirectional flow is used in areas such as material storage and personnel passages, which can not only meet certain cleanliness requirements but also reduce construction and operation costs. Design Highlights of Guangzhou Cleanroom Construction Co., Ltd.: When designing a mixed flow system, Guangzhou Cleanroom Construction Co., Ltd. will accurately divide the unidirectional flow and non-unidirectional flow areas. A transition area is set at the junction between the unidirectional flow and non-unidirectional flow areas. Through reasonable airflow organization design, the clean air in the unidirectional flow area can be prevented from being contaminated by the non-unidirectional flow area. At the same time, according to the functions and cleanliness requirements of different areas, the layout of the air supply outlets, air return outlets, as well as parameters such as the air supply volume and wind speed are adjusted respectively to ensure that the cleanliness of the entire workshop meets the Class 10,000 standard. III. Consideration Factors for Guangzhou Cleanroom Construction Co., Ltd. in Selecting Airflow Patterns (I) Production Process Requirements 1. Differences among Different Industries   The production processes of different industries have significantly different requirements for cleanliness and airflow patterns. The electronics industry is extremely sensitive to dust particles, especially in chip manufacturing, where unidirectional flow airflow patterns are often required to ensure the ultra-high cleanliness of the production environment. While the food industry also requires a clean environment, the control of microorganisms is more crucial. In some packaging processes, a non-unidirectional flow airflow pattern combined with good disinfection measures can meet the requirements. 2. Characteristics of Process Links   Even within the same industry, different process links have different requirements for airflow patterns. In the pharmaceutical industry, the filling process of sterile drugs has extremely high requirements for cleanliness, and unidirectional flow is usually adopted; while the outer packaging process of drugs has relatively lower requirements for cleanliness, and non-unidirectional flow can be used. Guangzhou Cleanroom Construction Co., Ltd. will deeply understand the production process of customers and select the most suitable airflow pattern according to the characteristics of different process links. (II) Space Layout and Cost 1. Space Factors   The space layout of the workshop has an important impact on the selection of the airflow pattern. For a long and narrow workshop, horizontal unidirectional flow may be more suitable, which can effectively transport clean air in a long space; while for a square or nearly square workshop, vertical unidirectional flow or non-unidirectional flow may be more likely to achieve a uniform airflow distribution. 2. Cost Considerations   The construction and operation costs of the unidirectional flow system are relatively high, requiring more high-efficiency filters, a higher air supply volume, and a more precise control system. The cost of the non-unidirectional flow system is relatively low. On the premise of meeting the cleanliness requirements of the production process, Guangzhou Cleanroom Construction Co., Ltd. will comprehensively consider the space layout of the workshop and the customer's budget, and select the airflow pattern with the highest cost performance to provide customers with an economical and reasonable solution. (III) Difficulty of Maintenance and Management 1. Maintenance Requirements   The unidirectional flow system has high requirements for equipment and filters, and the maintenance work is relatively complex, requiring regular replacement of high-efficiency filters and inspection of the performance of the fans. The maintenance of the non-unidirectional flow system is relatively simple, but it still requires regular inspection of whether the air supply outlets and air return outlets are blocked, as well as the operation status of the air conditioning system. Guangzhou Cleanroom Construction Co., Ltd. will explain in detail to customers the maintenance requirements and costs of different airflow patterns, and help customers select the airflow pattern that is easy to maintain and manage to ensure the long-term stable operation of the workshop. 2. Management Convenience   From the perspective of management, the mixed flow system has relatively high management difficulty due to the division of areas with different airflow patterns and parameter adjustment, and requires more professional personnel for operation and monitoring. While the single non-unidirectional flow system is relatively convenient to manage. Guangzhou Cleanroom Construction Co., Ltd. will provide appropriate suggestions on the airflow pattern according to the customer's management ability and personnel configuration to ensure that the airflow system of the workshop can be effectively managed and maintained.   The selection of the airflow pattern in a Class 10,000 clean workshop is a process that comprehensively considers various factors. With rich experience and a professional technical team, Guangzhou Cleanroom Construction Co., Ltd., on the basis of fully understanding the customer's needs, the characteristics of the production process, and the actual situation of the workshop, carefully designs the most suitable airflow pattern for customers to create a high-quality production environment that meets the Class 10,000 cleanliness standard.

I. The Relationship between the Cleanliness Grade of Clean Workshops and Filters   II. The Standard Requirements for Filters in Clean Workshops of Different Cleanliness Grades   Filter Type: High-efficiency particulate air (HEPA) filters must be used, which can achieve a filtration efficiency of over 99.97% for particles with a particle size ≥ 0.3μm. In some areas with extremely high cleanliness requirements, such as the photolithography workshop in electronic chip manufacturing, ultra-low penetration air (ULPA) filters may even be employed, which can achieve a filtration efficiency of over 99.999% for particles with a particle size ≥ 0.12μm. Quantity and Layout of Filters: Due to the extremely high cleanliness requirements of this grade of clean workshops, the filters need to be fully or nearly fully distributed on the ceiling. For instance, in an ISO 5 grade clean workshop with an area of 100 square meters, dozens or even hundreds of high-efficiency filters may be required to ensure that the air supplied to the workshop is almost free of dust particles. Medium-efficiency filters should also be installed at the air return outlets to prevent the filtered air from being re-contaminated during the circulation process.   Filter Type: The main filter is a high-efficiency particulate air filter, with a filtration efficiency of not less than 99.9% for particles with a particle size ≥ 0.3μm. Primary and medium-efficiency filters also need to be configured at the front end to form a three-stage filtration system. The primary-efficiency filter mainly filters large particles of dust, such as particles ≥ 5μm; the medium-efficiency filter further filters particles of medium particle size, such as particles ≥ 1μm. Quantity and Layout of Filters: The layout density of high-efficiency filters is relatively lower compared to that in ISO 5 grade clean workshops, but sufficient coverage still needs to be ensured. According to the area of the workshop and the design of the air flow organization, a high-efficiency filter may need to be installed for every 1 to 2 square meters. The primary-efficiency filters are generally installed at the fresh air inlet to initially filter the fresh air entering the workshop; the medium-efficiency filters are usually installed in the air conditioning unit to further purify the air that has passed through the primary-efficiency filtration.   Filter Type: A three-stage filtration system consisting of primary, medium, and high-efficiency filters is also adopted. The high-efficiency filter has a filtration efficiency of not less than 99.6% for particles with a particle size ≥ 0.3μm. Quantity and Layout of Filters: The installation quantity and density of high-efficiency filters are relatively lower than those in ISO 7 grade clean workshops. Depending on the actual situation of the workshop, a high-efficiency filter can be installed for every 2 to 3 square meters. The layout of the primary and medium-efficiency filters is similar to that in ISO 7 grade clean workshops, which are respectively responsible for the initial filtration of fresh air and the secondary filtration in the air conditioning unit. Workshop Area and Space Layout   Production Process and Pollution Sources   Air Flow Organization Form   IV. The Professional Advantages of Guangzhou Cleanroom Construction Co., Ltd. in the Configuration of Filters in Clean Workshops The team of Guangzhou Cleanroom Construction Co., Ltd. will have in-depth communication with customers at the initial stage of the project, and comprehensively understand key information such as the production process, the use function of the workshop, and the expected cleanliness grade. Through the comprehensive analysis of these factors, the configuration requirements of filters are accurately evaluated. For example, when undertaking the project of a sterile drug production workshop for a pharmaceutical enterprise, the company will accurately calculate the type, quantity, and layout of filters required for each area according to the specific production process of the drug, such as the cleanliness requirements of different links such as raw material processing, preparation preparation, and filling. Guangzhou Cleanroom Construction Co., Ltd. has established long-term cooperative relationships with many high-quality filter suppliers and strictly screens filter products that meet the standards. When selecting high-efficiency filters, not only the filtration efficiency is considered, but also performance indicators such as the resistance, dust holding capacity, and service life of the filters are examined. For key projects, filter products of well-known brands that have passed strict testing and certification will be selected to ensure the reliability of the quality and performance of the filters. The professional engineers of Guangzhou Cleanroom Construction Co., Ltd. conduct scientific layout design of filters according to the spatial structure, air flow organization form, and production process requirements of the workshop. Professional air flow simulation software is used to simulate and analyze different filter layout schemes, and optimize the installation position and quantity of filters to ensure that the air flow in the workshop is uniform and the cleanliness distribution is reasonable. For example, when designing the clean room for electronic chip packaging, the optimal installation angle and spacing of high-efficiency filters are determined through simulation analysis, so that the clean air can evenly cover the entire production area and effectively improve the cleanliness. After the completion of the clean workshop, Guangzhou Cleanroom Construction Co., Ltd. provides customers with comprehensive after-sales service, including the regular maintenance of filters and replacement guidance. A detailed filter maintenance plan is formulated, and customers are visited regularly to check the operation status of the filters, and potential problems are discovered and solved in a timely manner. At the same time, technical support and training for filter replacement are provided to customers to ensure that customers can correctly replace the filters and maintain the cleanliness of the workshop.

In the medical field, the pathology department, as the "gold standard" department for disease diagnosis, its work efficiency is directly related to the patient's diagnosis and treatment process. A scientific and reasonable layout of the department is like pressing the "fast - forward button" for the work efficiency of the pathology department. Guangzhou Cleanroom Construction Co., Ltd., as a professional manufacturer deeply engaged in the purification equipment field, deeply understands the importance of the layout of the pathology department. The following is a detailed analysis for you. I. The Close Connection between the Work Process and Layout of the Pathology Department The work of the pathology department covers multiple links such as specimen reception, fixation, sampling, slide preparation, staining, and diagnosis. A reasonable layout needs to be based on these processes to achieve seamless connection of each link. For example, the specimen reception area should be close to the entrance of the department for convenient and quick specimen collection; and the slide - making area and the staining area should be set adjacent to each other to reduce the back - and - forth 奔波 of materials and personnel. Such a layout can greatly shorten the working time and improve the overall efficiency. II. The Key Role of Purification Equipment in the Layout of the Pathology Department 1. Air Purification Equipment During the specimen processing in the pathology department, various harmful gases and microorganisms such as formaldehyde and xylene will be generated. The air purification equipment of our company adopts high - efficiency filtration technology, which can effectively remove these pollutants and ensure that the air quality inside the department meets the standards. When laying out, the purification equipment is reasonably placed in each work area, such as the sampling room and the sectioning room, to create a healthy working environment for the staff and also extend the service life of the equipment and instruments. 2. Ventilation System Good ventilation is an indispensable part of the layout of the pathology department. The ventilation system we provide can ensure the rapid circulation of indoor air and timely discharge harmful gases. The design of the position of the air vents is also very crucial. It needs to be planned according to the spatial structure of the department and the placement of equipment to avoid ventilation dead corners and ensure a uniform ventilation effect throughout the department. III. Layout Strategies for Maximizing Space Utilization The pathology department often faces the problem of limited space. How to achieve an efficient layout within a limited space is of great importance. We suggest adopting a modular layout design, integrating areas with similar functions together to form relatively independent yet interrelated modules. For example, small - sized equipment and instruments are placed on a movable workbench, which is convenient to adjust the position according to work needs. At the same time, make use of the space on the walls and ceilings to install wall - hung cabinets and hanging racks to increase storage space, making the department environment neater and more orderly, and further improving work efficiency.
