Cleanrooms are special facilities with extremely strict environmental requirements. The final acceptance work for cleanrooms is of utmost importance. It directly affects whether the workshop can be put into normal use and the quality and safety of subsequent production activities. As a professional manufacturer of purification equipment, Guangzhou Cleanroom Construction Co., Ltd. has rich experience in the construction of cleanrooms. Today, we will deeply analyze the key items for the final acceptance of cleanrooms. I. Acceptance of the Air Purification System (I) Filter Performance Testing Filtration Efficiency：High - Efficiency Particulate Air (HEPA) filters and Ultra - Low - Penetration Air (ULPA) filters are the core components of air purification in cleanrooms. During the acceptance process, professional testing equipment such as particle counters should be used to test the filtration efficiency of the filters. For example, for HEPA filters, it is necessary to ensure that the filtration efficiency for particles with a particle size of 0.3 microns reaches over 99.97%. If the filtration efficiency does not meet the standard, there will be too many dust particles in the workshop, affecting product quality. Integrity Testing：Methods such as scanning tests are used to check whether there are any breakages or leaks in the filters. Even a tiny hole may allow unfiltered air to enter the workshop and damage the clean environment. Once a problem with the filter is detected, it must be replaced in a timely manner to ensure the normal operation of the air purification system. (II) Air Volume and Air Velocity Testing Air Supply Volume：An appropriate air supply volume is the basis for maintaining the cleanliness of the workshop. During the acceptance, measure the air volume of each air supply outlet to ensure that the total air supply volume meets the design requirements. Insufficient air supply volume cannot effectively dilute the pollutants in the workshop; excessive air supply volume may cause energy waste and air flow turbulence in the workshop. Air Velocity：Test the air velocity in key areas of the room, such as the working area and near the air return vents. Different levels of cleanrooms have different requirements for air velocity. For example, the air velocity in general clean areas should be maintained at 0.25 - 0.35 m/s. Uneven air velocity or air velocity not in line with the standard will affect the air circulation and the discharge effect of pollutants. (III) Pressure Difference Testing There needs to be a certain pressure difference between different areas in the cleanroom to prevent the diffusion of pollutants. During the acceptance, test the pressure difference between the clean area and the non - clean area, as well as between different clean - level areas. Usually, the clean area should maintain a positive pressure of not less than 10 Pa relative to the non - clean area; the pressure difference between adjacent different clean - level areas should be not less than 5 Pa. Through reasonable pressure - difference settings, a trend of air flow from high - clean - level areas to low - clean - level areas is formed to avoid cross - contamination. II. Acceptance of Temperature and Humidity Control (I) Temperature Testing According to the production process requirements of the workshop, conduct multi - point temperature testing in the workshop during the acceptance. For example, in the cleanroom for electronic chip manufacturing, the temperature generally needs to be controlled at 22±2°C. Too high or too low a temperature may affect the performance and production efficiency of the products. Through temperature sensors installed in the workshop, real - time temperature data is monitored and compared with the design requirements to ensure that the temperature is controlled within a reasonable range. (II) Humidity Testing Humidity is also crucial for the production of some products. For example, in a pharmaceutical production workshop, the humidity is usually controlled between 45% - 65%RH. Excessive humidity is likely to breed microorganisms and affect the quality of drugs; too low humidity may generate static electricity and cause damage to electronic products. Use high - precision humidity testing instruments to test the humidity at different positions in the workshop to ensure that the humidity meets the production requirements. III. Microbial Testing (I) Floating Bacteria Testing Use a floating bacteria sampler to sample at different heights and in different areas of the workshop. After sampling, cultivate the collected samples and calculate the number of floating bacteria per unit volume of air. Different clean - level workshops have clear regulations on the allowable limits of floating bacteria. For example, the number of floating bacteria in a Class 100 cleanroom shall not exceed 5 CFU/m³. If the number of floating bacteria exceeds the standard, it indicates a high risk of microbial contamination in the workshop, which may affect the sterility and quality of products. (II) Settling Bacteria Testing Place petri dishes in the workshop to allow microorganisms in the air to naturally settle on the culture medium. After a certain period of cultivation, count the number of colonies on the petri dishes. Settling bacteria testing can reflect the settlement of microorganisms in the workshop and also needs to meet the corresponding clean - level standards. For example, the number of settling bacteria in a Class 10,000 cleanroom shall not exceed 10 CFU/dish (30 minutes). IV. Acceptance of Lighting and Electrostatic Protection (I) Lighting Testing Illuminance Testing：Use an illuminance meter to measure the illuminance of each working area in the workshop. Appropriate illuminance can ensure that operators can clearly carry out production operations, improving work efficiency and quality. Generally, the illuminance requirements for cleanrooms are between 300 - 500 lx, and the specific value depends on the production process and operation requirements. Lighting Uniformity：In addition to the illuminance value, also pay attention to the lighting uniformity. Avoid situations where some areas are too bright or too dark, and ensure that the light is evenly distributed throughout the workshop to reduce visual fatigue. (II) Electrostatic Protection Testing Grounding Resistance Testing：Equipment, workbenches, floors, etc. in the cleanroom all need to be well - grounded to prevent the accumulation of static electricity. During the acceptance, test the grounding resistance to ensure that it meets relevant standards. Generally, the grounding resistance is required to be no greater than 4Ω. Effect Testing of Electrostatic Eliminators：For workshops equipped with electrostatic eliminators, test the effect of static electricity elimination. Use equipment such as electrostatic testers to measure the electrostatic voltage on the surface of objects and check whether the electrostatic elimination equipment can effectively reduce the electrostatic level and protect products from electrostatic damage.

During the drug production process, ensuring the quality and safety of drugs is of utmost importance. As a crucial place for drug production, preventing cross - contamination of drugs in pharmaceutical cleanrooms is one of the core tasks to guarantee drug quality. As a professional manufacturer of purification equipment, Guangzhou Cleanroom Construction Co., Ltd. has rich experience in the construction and maintenance of pharmaceutical cleanrooms. Today, we will discuss in detail how to effectively prevent cross - contamination of drugs in pharmaceutical cleanrooms. I. Rational Workshop Layout Planning (I) Clear Functional Area Division Pharmaceutical cleanrooms should clearly divide different functional areas according to the production process, such as raw material storage areas, production areas, intermediate product storage areas, packaging areas, etc. Each area should be relatively independent. By setting up physical isolation facilities such as walls and buffer rooms, the random flow of air, materials, and personnel between different areas can be prevented, thus reducing the risk of cross - contamination. For example, processes with high dust generation, such as pulverization and granulation, should be set up in separate rooms and equipped with effective dust - removal devices to avoid dust diffusion and contamination of drugs in other areas. (II) Separation of People and Material Flow Passages Strictly distinguish between the access passages for personnel and materials to avoid cross - flow during the movement of personnel and materials. The personnel passage should be equipped with changing rooms, hand - washing and disinfection rooms, etc., to ensure that personnel are fully purified and disinfected before entering the workshop. The material passage should be equipped with material transfer windows, buffer rooms, and other facilities to clean and disinfect the materials entering the workshop, preventing pollutants carried by the materials from entering the production area. II. Stringent Personnel Management (I) Personnel Training Regularly train workshop staff, and the training content includes Good Manufacturing Practice (GMP) for drug production, hygiene knowledge, operating procedures, etc. Enable employees to fully understand the hazards of cross - contamination and how to avoid cross - contamination in their work. For example, teach employees the correct hand - washing methods, the norms for wearing work clothes, and how to avoid contact between different drugs during operations. (II) Health Management Establish employee health files and conduct regular health checks on employees. Personnel suffering from infectious diseases, skin diseases, or other diseases that may affect drug quality are strictly prohibited from entering the workshop. At the same time, employees are required to report promptly and take corresponding measures if they feel unwell during work to prevent drug contamination due to employee health problems. III. Standardized Material Management (I) Receiving and Storage of Materials When receiving materials, strictly check whether the packaging of the materials is intact and whether the labels are clear and accurate. After the materials are inspected and accepted as qualified, store them according to the specified storage conditions. Different varieties and specifications of materials should be stored separately and clearly labeled. For volatile and easily contaminated materials, measures such as sealed storage should be taken to prevent them from contaminating other materials. (II) Transfer and Use of Materials The transfer of materials in the workshop should follow the specified routes and procedures to avoid contamination of materials during the transfer process. When using materials, strictly follow the operating procedures, use materials specifically for their intended purposes, and avoid mixing materials of different drugs. For example, during the batching process, ensure the cleanliness and accuracy of weighing instruments to prevent residual materials from contaminating subsequent batches. IV. Equipment Cleaning and Maintenance (I) Equipment Cleaning Formulate strict equipment cleaning procedures, clarify the methods, frequencies, and selection of cleaning agents for equipment cleaning. After each production is completed, clean the equipment in a timely manner to ensure that there is no material residue on the equipment surface. For difficult - to - clean parts, use special cleaning tools and methods for treatment. At the same time, inspect and verify the cleaned equipment to ensure that the equipment cleaning effect meets the requirements. (II) Equipment Maintenance Regularly maintain and service the equipment to ensure its normal operation. During equipment maintenance, pay attention to preventing maintenance tools, spare parts, etc. from contaminating the equipment and drugs. For example, when replacing equipment parts, clean and disinfect the new parts to avoid introducing contaminants. V. Effective Air Purification and Disinfection (I) Air Purification System Install an efficient air purification system, such as a combination of primary - effect, medium - effect, and high - efficiency filters, to filter the air entering the workshop and remove dust particles, microorganisms, and other pollutants in the air. At the same time, regularly detect and maintain the air purification system to ensure its filtration efficiency and operating effect. (II) Environmental Disinfection Regularly disinfect the workshop environment, which can be achieved by means of ultraviolet irradiation, chemical disinfectant spraying, etc. During the disinfection process, pay attention to the selection and use methods of disinfectants to ensure the disinfection effect while avoiding drug contamination caused by disinfectant residues.

In the construction and operation of cleanrooms, the control of positive and negative pressures in the airflow is a crucial factor. It has a vital impact on the cleanliness of the workshop, product quality, and the safety of personnel and the environment. As a professional manufacturer of purification equipment, Guangzhou Cleanroom Construction Co., Ltd. will discuss in detail the role and difference of positive and negative pressures in cleanroom airflow with you today. I. The Role of Positive Pressure (I) Preventing External Contaminants from Entering Maintaining a positive pressure in the cleanroom means that the air pressure inside the workshop is higher than that of the external environment. In this way, at the openings such as doors and windows of the workshop, the air will flow from the inside to the outside. It's like an invisible "air barrier" formed around the workshop, effectively preventing external dust, bacteria, harmful gases and other contaminants from entering the workshop. For example, in the cleanrooms for electronic chip manufacturing, positive pressure can prevent tiny particles in the air from adhering to the chips, affecting the performance and quality of the chips. (II) Maintaining a Clean Environment Inside the Workshop Positive pressure helps to maintain the orderly flow of air inside the workshop, continuously refreshing the air in the workshop. When a small amount of contaminants are generated inside the workshop, the airflow in the positive - pressure environment will promptly carry these contaminants away from key areas. After being filtered by the air purification system, the air is discharged from the workshop, ensuring that the entire workshop is always in a good clean state. II. The Role of Negative Pressure (I) Controlling the Diffusion of Harmful Substances In some workshops that generate harmful gases, dust, or bio - aerosols, such as chemical laboratories and some areas of biopharmaceutical workshops, a negative - pressure design is adopted. Negative pressure makes the air pressure inside the workshop lower than that of the external environment, and the air will flow from the outside to the inside of the workshop. In this way, it can ensure that the harmful substances generated inside the workshop will not leak to the outside but are confined within the workshop. They are then discharged after being treated by a special exhaust system, avoiding harm to the surrounding environment and personnel. (II) Ensuring Personnel Safety For some cleanrooms involving high - risk operations, such as infectious disease research laboratories, the negative - pressure environment can effectively protect the safety of personnel outside the laboratory. Even if an accident occurs during the operation, such as the rupture of a container resulting in the leakage of harmful substances, the negative pressure can prevent the harmful substances from escaping from the workshop, reducing the risk of personnel exposure to dangerous environments. III. The Differences between Positive and Negative Pressures (I) Airflow Direction The airflow direction in a positive - pressure workshop is from the inside to the outside of the workshop, while the airflow direction in a negative - pressure workshop is from the outside to the inside of the workshop. This difference in airflow direction directly determines their different functions in preventing contaminants from entering and controlling the diffusion of harmful substances. (II) Applicable Scenarios Positive pressure is suitable for places that need to strictly protect the internal environment from external pollution, such as cleanrooms in the food processing and precision electronics manufacturing industries. Negative pressure is mainly applied to scenarios where harmful substances are generated and need to be prevented from leaking to the outside, such as chemical production and biosafety laboratories. (III) Equipment Configuration To achieve positive pressure, a cleanroom needs to be equipped with a suitable fresh - air system and air - supply equipment to ensure that the amount of air supplied to the workshop is greater than the amount of air discharged. A negative - pressure workshop, on the other hand, requires a more powerful exhaust system to ensure that the air in the workshop can be discharged in a timely manner. At the same time, the amount of fresh air entering needs to be strictly controlled to maintain a negative - pressure state. (IV) Pressure Control Accuracy The requirement for pressure control accuracy in a positive - pressure workshop is relatively low. Generally, it only needs to ensure that the pressure inside the workshop is slightly higher than that outside. In order to effectively control the diffusion of harmful substances, a negative - pressure workshop has a high requirement for pressure control accuracy. It is necessary to precisely adjust the air supply and exhaust volumes to ensure that the negative - pressure value remains stable within an appropriate range. Guangzhou Cleanroom Construction Co., Ltd. has rich experience and a professional technical team. We can provide you with accurate solutions for positive and negative pressures in cleanrooms according to the different needs of customers. Whether it is the configuration of purification equipment for positive - pressure workshops or the system design, installation, and commissioning of negative - pressure workshops, we can provide you with one - stop services.
