How long is the cleaning and maintenance cycle of the DOP HEPA box?
How long is the cleaning and maintenance cycle of the DOP HEPA box?In recent years, the new version of GMP has significantly increased the requirements for air purification in the core areas of pharmaceutical production (such as Class A areas, A+B areas, etc.). At the same time, in the past few years, in liquid tank sealing technology, the development of new frame structures and the development and improvement of new liquid tank sealants (commonly known as jelly glue) have greatly increased the use of liquid tank high-efficiency air supply outlets. Gradually become the mainstream sealing method for high-grade clean environments.Cleaning and maintenance are inevitable during use. The cleaning and maintenance cycle of the liquid tank high-efficiency air supply outlet will be affected by many factors, such as the cleanliness of the use environment, the frequency of use of the air supply outlet, and the quality of the treated air. As a manufacturer of liquid tank high-efficiency air supply outlets, Guangzhou Baiyun recommends the following cleaning and maintenance cycles: 1. Replacement of high-efficiency filters The high-efficiency filter is the core component of the liquid tank high-efficiency air supply outlet, and its replacement cycle is usually 6-12 months. However, if the air supply area has extremely high requirements for air quality, or there is a lot of dust and particulate matter in the use environment, the replacement cycle may need to be shortened. When it is found that the resistance of the high-efficiency filter has increased significantly, or the cleanliness measured by the dust particle counter does not meet the requirements, the high-efficiency filter should be replaced in time. 2. Regular dust particle counting detection Every two months or so, it is recommended to use a dust particle counter to measure the cleanliness of the area after purification by the liquid tank's high-efficiency air supply outlet. This can timely detect changes in the purification effect. When the measured cleanliness does not meet the required cleanliness, the cause should be found. Possible reasons include filter leakage, high-efficiency filter failure, etc. If it is determined that the high-efficiency filter has failed, a new filter needs to be replaced immediately. 3. Daily appearance inspection In daily use, the appearance of the liquid tank high-efficiency air supply outlet should be checked frequently. Check whether the air supply outlet box is damaged, whether there are signs of leakage at the seal, etc. 4. Handling of special situations If the environment of the liquid tank high-efficiency air supply outlet is relatively harsh, such as more dust, corrosive gases, or high humidity, the frequency of cleaning and maintenance may need to be increased accordingly. For example, in a high-dust environment, the filter may accumulate dust faster and need to be checked and replaced more frequently. In addition, the following points should be noted during cleaning and maintenance: 1. Be especially careful when replacing the high-efficiency filter to avoid direct contact with the filter paper and causing damage. Ensure that the filter paper is intact during unpacking, transportation, installation, and use. 2. Before installing a new high-efficiency filter, face it to a bright place and observe with the naked eye whether it is damaged due to transportation or other reasons. If there are holes in the filter paper, it cannot be used. 3. When cleaning the liquid tank, appropriate cleaning tools and methods should be used to avoid damaging the sealing performance of the liquid tank. 4. Check the sealing performance of the liquid tank to ensure that it is well sealed and there is no leakage. 5. During maintenance, if other parts are found to be damaged or aged, they should be repaired or replaced in time. It should be noted that the above cleaning and maintenance cycles are only for reference and should be flexibly adjusted according to specific circumstances in actual operation. Reasonable cleaning and maintenance can ensure the stable performance of the liquid tank high-efficiency air outlet and effectively maintain the cleanliness of the air supply area. At the same time, it is recommended that professionals perform cleaning and maintenance operations to ensure the correctness and safety of the operation. If you have more detailed requirements for the cleaning and maintenance of the high-efficiency air outlet of the liquid tank under specific conditions, you can refer to the relevant equipment manual or consult a professional purification equipment supplier. |
